>gnl|CDD|143346 cd07841, STKc_CDK7, Catalytic domain of the Serine/Threonine
Kinase, Cyclin-Dependent protein Kinase 7.
Serine/Threonine Kinases (STKs), Cyclin-Dependent
protein Kinase 7 (CDK7) subfamily, catalytic (c) domain.
STKs catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine residues on protein
substrates. The CDK7 subfamily is part of a larger
superfamily that includes the catalytic domains of other
protein STKs, protein tyrosine kinases, RIO kinases,
aminoglycoside phosphotransferase, choline kinase, and
phosphoinositide 3-kinase. CDKs belong to a large family
of STKs that are regulated by their cognate cyclins.
Together, they are involved in the control of cell-cycle
progression, transcription, and neuronal function. CDK7
plays essential roles in the cell cycle and in
transcription. It associates with cyclin H and MAT1 and
acts as a CDK-Activating Kinase (CAK) by phosphorylating
and activating cell cycle CDKs (CDK1/2/4/6). In the
brain, it activates CDK5. CDK7 is also a component of
the general transcription factor TFIIH, which
phosphorylates the C-terminal domain (CTD) of RNA
polymerase II when it is bound with unphosphorylated
DNA, as present in the pre-initiation complex. Following
phosphorylation, the CTD dissociates from the DNA which
allows transcription initiation.

>gnl|CDD|173733 cd07829, STKc_CDK_like, Catalytic domain of Cyclin-Dependent
protein Kinase-like Serine/Threonine Kinases.
Serine/Threonine Kinases (STKs), Cyclin-Dependent
protein Kinase (CDK)-like subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The CDK-like subfamily
is part of a larger superfamily that includes the
catalytic domains of other protein STKs, protein
tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. CDKs belong to a large family of STKs that are
regulated by their cognate cyclins. Together, they are
involved in the control of cell-cycle progression,
transcription, and neuronal function. CDKs are partly
regulated by their subcellular localization, which
defines substrate phosphorylation and the resulting
specific function. CDK1, CDK2, CDK4, and CDK6 have
well-defined functions in the cell cycle, such as the
regulation of the early G1 phase by CDK4 or CDK6, the
G1/S phase transition by CDK2, or the entry of mitosis
by CDK1. They also exhibit overlapping cyclin
specificity and functions in certain conditions.
Knockout mice with a single CDK deleted remain viable
with specific phenotypes, showing that some CDKs can
compensate for each other. For example, CDK4 can
compensate for the loss of CDK6, however, double
knockout mice with both CDK4 and CDK6 deleted die in
utero. CDK8 and CDK9 are mainly involved in
transcription while CDK5 is implicated in neuronal
function. CDK7 plays essential roles in both the cell
cycle as a CDK-Activating Kinase (CAK) and in
transcription as a component of the general
transcription factor TFIIH.

CCRK subfamily is part of a larger superfamily that
includes the catalytic domains of other protein STKs,
protein tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. CCRK was previously called p42. It is a
Cyclin-Dependent Kinase (CDK)-Activating Kinase (CAK)
which is essential for the activation of CDK2. It is
indispensable for cell growth and has been implicated in
the progression of glioblastoma multiforme. In the
heart, a splice variant of CCRK with a different
C-terminal half is expressed, this variant promotes
cardiac cell growth and survival and is significantly
down-regulated during the development of heart failure.

Kinases (STKs), Cell Division Cycle 2-like 1 (CDC2L1)
subfamily, catalytic (c) domain. STKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
serine/threonine residues on protein substrates. The
CDC2L1 subfamily is part of a larger superfamily that
includes the catalytic domains of other protein STKs,
protein tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. CDKs belong to a large family of STKs that are
regulated by their cognate cyclins. Together, they are
involved in the control of cell-cycle progression,
transcription, and neuronal function. CDC2L1, also
called PITSLRE, exists in different isoforms which are
named using the alias CDK11(p). The CDC2L1 gene produces
two protein products, CDK11(p110) and CDK11(p58). CDC2L1
is also represented by the caspase-processed CDK11(p46).
CDK11(p110), the major isoform, associates with cyclin L
and is expressed throughout the cell cycle. It is
involved in RNA processing and the regulation of
transcription. CDK11(p58) associates with cyclin D3 and
is expressed during the G2/M phase of the cell cycle. It
plays roles in spindle morphogenesis, centrosome
maturation, sister chromatid cohesion, and the
completion of mitosis. CDK11(p46) is formed from the
larger isoforms by caspases during TNFalpha- and
Fas-induced apoptosis. It functions as a downstream
effector kinase in apoptotic signaling pathways and
interacts with eukaryotic initiation factor 3f (eIF3f),
p21-activated kinase (PAK1), and Ran-binding protein
(RanBPM).

involved in the control of cell-cycle progression,
transcription, and neuronal function. This subfamily is
composed of CDK9 and CDK12 from higher eukaryotes, yeast
BUR1, C-type plant CDKs (CdkC), and similar proteins.
CDK9, BUR1, and CdkC are functionally equivalent. They
act as a kinase for the C-terminal domain of RNA
polymerase II and participate in regulating mutliple
steps of gene expression including transcription
elongation and RNA processing. CDK9 and CdkC associate
with T-type cyclins while BUR1 associates with the
cyclin BUR2. CDK12 is a unique CDK that contains an
arginine/serine-rich (RS) domain, which is predominantly
found in splicing factors. CDK12 interacts with cyclins
L1 and L2, and participates in regulating transcription
and alternative splicing.

Serine/Threonine Kinases (STKs), Cyclin-Dependent
protein Kinase 1 (CDK1)-like subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The CDK1 subfamily is
part of a larger superfamily that includes the catalytic
domains of other protein STKs, protein tyrosine kinases,
RIO kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. CDKs belong to a
large family of STKs that are regulated by their cognate
cyclins. Together, they are involved in the control of
cell-cycle progression, transcription, and neuronal
function. This subfamily is composed of CDK1 from higher
eukaryotes, plants, and yeasts, as well as CDK2 and
CDK3. CDK1 is also called Cell division control protein
2 (Cdc2) or p34 protein kinase, and is regulated by
cyclins A, B, and E. The CDK1/cyclin A complex controls
G2 phase entry and progression while the CDK1/cyclin B
complex is critical for G2 to M phase transition. CDK2
is regulated by cyclin E or cyclin A. Upon activation by
cyclin E, it phosphorylates the retinoblastoma (pRb)
protein which activates E2F mediated transcription and
allows cells to move into S phase. The CDK2/cyclin A
complex plays a role in regulating DNA replication.
Studies in knockout mice revealed that CDK1 can
compensate for the loss of the cdk2 gene as it can also
bind cyclin E and drive G1 to S phase transition. CDK3
is regulated by cyclin C and it phosphorylates pRB
specifically during the G0/G1 transition. This
phosphorylation is required for cells to exit G0
efficiently and enter the G1 phase.

activating nuclear enzymes that regulate chromatin
condensation, nuclear membrane degradation,
mitosis-specific microtubule and cytoskeletal
reorganization. CDK1 also associates with cyclin E and
plays a role in the entry into S phase. CDK1
transcription is stable throughout the cell cycle but is
modulated in some pathological conditions. It may play a
role in regulating apoptosis under these conditions. In
breast cancer cells, HER2 can mediate apoptosis by

also regulates embryonic cell proliferation. Despite
these important roles, mice deleted for the cdk2 gene
are viable and normal except for being sterile. This may
be due to compensation provided by CDK1 (also called
Cdc2), which can also bind cyclin E and drive the G1 to

which transmits the signal either directly to a MAP3K to
start the triple kinase core cascade or indirectly
through a mediator kinase, a MAP4K. There are three main
typical MAPK subfamilies: Extracellular signal-Regulated
Kinase (ERK), c-Jun N-terminal Kinase (JNK), and p38.
Some MAPKs are atypical in that they are not regulated
by MAP2Ks. These include MAPK4, MAPK6, NLK, and ERK7.

Serine/Threonine Kinases (STKs), Male germ
cell-Associated Kinase (MAK)-like subfamily, catalytic
(c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The MAK-like subfamily
is part of a larger superfamily that includes the
catalytic domains of other protein STKs, protein
tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. This subfamily is composed of human MAK and
MAK-related kinase (MRK), Saccharomyces cerevisiae
Ime2p, Schizosaccharomyces pombe Mei4-dependent protein
3 (Mde3) and Pit1, Caenorhabditis elegans dyf-5,
Arabidopsis thaliana MHK, and similar proteins. These
proteins play important roles during meiosis. MAK is
highly expressed in testicular cells specifically in the
meiotic phase, but is not essential for spermatogenesis
and fertility. It functions as a coactivator of the
androgen receptor in prostate cells. MRK, also called
Intestinal Cell Kinase (ICK), is expressed ubiquitously,
with highest expression in the ovary and uterus. A
missense mutation in MRK causes
endocrine-cerebro-osteodysplasia (ECO), suggesting that
this protein plays an important role in the development
of many organs. MAK and MRK may be involved in
regulating cell cycle and cell fate. Ime2p is a
meiosis-specific kinase that is important during meiotic
initiation and during the later stages of meiosis. Mde3
functions downstream of the transcription factor Mei-4
which is essential for meiotic prophase I.

protein. They are also regulated by the INK4 family of
inhibitors which associate with either the CDK alone or
the CDK/cyclin complex. CDK4 and CDK6 show differences
in subcellular localization, sensitivity to some
inhibitors, timing in activation, tumor selectivity, and
possibly substrate profiles. Although CDK4 and CDK6 seem
to show some redundancy, they also have discrete,
nonoverlapping functions. CDK6 plays an important role
in cell differentiation.

important mediators of cellular responses to
extracellular signals. ERK5, also called Big MAPK1
(BMK1) or MAPK7, has a unique C-terminal extension,
making it approximately twice as big as other MAPKs.
This extension contains transcriptional activation
capability which is inhibited by the N-terminal half.
ERK5 is activated in response to growth factors and
stress by a cascade that leads to its phosphorylation by
the MAP2K MEK5, which in turn is regulated by the MAP3Ks
MEKK2 and MEKK3. Activated ERK5 phosphorylates its
targets including myocyte enhancer factor 2 (MEF2),
Sap1a, c-Myc, and RSK. It plays a role in EGF-induced
cell proliferation during the G1/S phase transition.
Studies on knockout mice revealed that ERK5 is essential
for cardiovascular development and plays an important
role in angiogenesis. It is also critical for neural
differentiation and survival. The ERK5 pathway has been
implicated in the pathogenesis of many diseases
including cancer, cardiac hypertrophy, and
atherosclerosis.

of plant MAPKs based on the conserved phosphorylation
motif present in the activation loop, TEY and TDY. This
subfamily represents the TEY subtype and is further
subdivided into three groups (A, B, and C). Group A is
represented by AtMPK3, AtMPK6, Nicotiana tabacum BTF4

cell division and environmental stress response. AtMPK4
also participates in regulating innate immunity. Group C
is represented by AtMPK1, AtMPK2, NtNTF3, Oryza sativa

in stress responses. AtMPK1 and AtMPK2 are activated
following mechanical injury and in the presence of

STKs catalyze the transfer of the gamma-phosphoryl group

substrates. The NLK subfamily is part of a larger
superfamily that includes the catalytic domains of other
protein STKs, protein tyrosine kinases, RIO kinases,

phosphoinositide 3-kinase. Mitogen-activated protein
kinases (MAPKs) are important mediators of cellular
responses to extracellular signals. NLK is an atypical
MAPK that is not regulated by a MAPK kinase. It
functions downstream of the MAPK kinase kinase Tak1,
which also plays a role in activating the JNK and p38
MAPKs. The Tak1/NLK pathways are regulated by Wnts, a
family of secreted proteins that is critical in the
control of asymmetric division and cell polarity. NLK
can phosphorylate transcription factors from the TCF/LEF
family, inhibiting their ability to activate the
transcription of target genes. In prostate cancer cells,
NLK is involved in regulating androgen receptor-mediated
transcription and its expression is altered during
cancer progression.

mediators of cellular responses to extracellular
signals. Sty1 and Hog1 are stress-activated MAPKs that
partipate in transcriptional regulation in response to
stress. Sty1 is activated in response to oxidative
stress, osmotic stress, and UV radiation. Sty1 is
regulated by the MAP2K Wis1, which is activated by the
MAP3Ks Wis4 and Win1, which receive signals of the
stress condition from membrane-spanning histidine
kinases Mak1-3. Activated Sty1 stabilizes the Atf1
transcription factor and induces transcription of
Atf1-dependent genes of the core environmetal stress
response (CESR). Hog1 is the key element in the high
osmolarity glycerol (HOG) pathway and is activated upon
hyperosmotic stress. Activated Hog1 accumulates in the
nucleus and regulates stress-induced transcription. The
HOG pathway is mediated by two transmembrane
osmosensors, Sln1 and Sho1.

of the gamma-phosphoryl group from ATP to

substrates. The PK family is part of a larger
superfamily that includes the catalytic domains of RIO
kinases, aminoglycoside phosphotransferase, choline
kinase, phosphoinositide 3-kinase (PI3K), and
actin-fragmin kinase. PKs make up a large family of
serine/threonine kinases, protein tyrosine kinases
(PTKs), and dual-specificity PKs that phosphorylate both
serine/threonine and tyrosine residues of target
proteins. Majority of protein phosphorylation, about
95%, occurs on serine residues while only 1% occurs on
tyrosine residues. Protein phosphorylation is a
mechanism by which a wide variety of cellular proteins,
such as enzymes and membrane channels, are reversibly
regulated in response to certain stimuli. PKs often
function as components of signal transduction pathways
in which one kinase activates a second kinase, which in
turn, may act on other kinases; this sequential action
transmits a signal from the cell surface to target
proteins, which results in cellular responses. The PK
family is one of the largest known protein families with
more than 100 homologous yeast enzymes and 550 human
proteins. A fraction of PK family members are
pseudokinases that lack crucial residues for catalytic
activity. The mutiplicity of kinases allows for specific
regulation according to substrate, tissue distribution,
and cellular localization. PKs regulate many cellular
processes including proliferation, division,
differentiation, motility, survival, metabolism,
cell-cycle progression, cytoskeletal rearrangement,
immunity, and neuronal functions. Many kinases are
implicated in the development of various human diseases
including different types of cancer.

of a larger superfamily that includes the catalytic
domains of other protein STKs, protein tyrosine kinases,
RIO kinases, aminoglycoside phosphotransferase, choline

Receptor Kinase (GRK), Serum- and Glucocorticoid-induced
Kinase (SGK), and 70 kDa ribosomal Protein S6 Kinase
(p70S6K or S6K), among others. AGC kinases share an
activation mechanism based on the phosphorylation of up
to three sites: the activation loop (A-loop), the
hydrophobic motif (HM) and the turn motif.
Phosphorylation at the A-loop is required of most AGC
kinases, which results in a disorder-to-order transition
of the A-loop. The ordered conformation results in the
access of substrates and ATP to the active site. A
subset of AGC kinases with C-terminal extensions
containing the HM also requires phosphorylation at this
site. Phosphorylation at the HM allows the C-terminal
extension to form an ordered structure that packs into
the hydrophobic pocket of the catalytic domain, which
then reconfigures the kinase into an active bi-lobed
state. In addition, growth factor-activated AGC kinases
such as PKB, p70S6K, RSK, MSK, PKC, and SGK, require
phosphorylation at the turn motif (also called tail or
zipper site), located N-terminal to the HM at the
C-terminal extension. AGC kinases regulate many cellular
processes including division, growth, survival,
metabolism, motility, and differentiation. Many are
implicated in the development of various human diseases.

substrates. The cGK subfamily is part of a larger
superfamily that includes the catalytic domains of other
protein STKs, protein tyrosine kinases, RIO kinases,
aminoglycoside phosphotransferase, choline kinase, and
phosphoinositide 3-kinase. Mammals have two cGK isoforms
from different genes, cGKI and cGKII. cGKI exists as two
splice variants, cGKI-alpha and cGKI-beta. cGK consists
of an N-terminal regulatory domain containing a
dimerization and an autoinhibitory pseudosubstrate
region, two cGMP-binding domains, and a C-terminal
catalytic domain. Binding of cGMP to both binding sites
releases the inhibition of the catalytic center by the
pseudosubstrate region, allowing autophosphorylation and
activation of the kinase. cGKI is a soluble protein
expressed in all smooth muscles, platelets, cerebellum,
and kidney. It is also expressed at lower concentrations
in other tissues. cGKII is a membrane-bound protein that
is most abundantly expressed in the intestine. It is
also present in the brain nuclei, adrenal cortex,
kidney, lung, and prostate. cGKI is involved in the
regulation of smooth muscle tone, smooth cell
proliferation, and platelet activation. cGKII plays a
role in the regulation of secretion, such as renin
secretion by the kidney and aldosterone secretion by the
adrenal. It also regulates bone growth and the circadian
rhythm.

Serine/threonine kinases (STKs), Apoptosis
signal-regulating kinase (ASK) subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The ASK subfamily is
part of a larger superfamily that includes the catalytic
domains of other protein STKs, protein tyrosine kinases,
RIO kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. Subfamily members
are mitogen-activated protein kinase (MAPK) kinase
kinases (MAPKKKs or MKKKs or MAP3Ks) and include ASK1,
ASK2, and MAPKKK15. MAPKKKs phosphorylate and activate
MAPK kinases (MAPKKs or MKKs or MAP2Ks), which in turn
phosphorylate and activate MAPKs during signaling
cascades that are important in mediating cellular
responses to extracellular signals. ASK1 (also called
MAPKKK5) functions in the c-Jun N-terminal kinase (JNK)
and p38 MAPK signaling pathways by directly activating
their respective MAPKKs, MKK4/MKK7 and MKK3/MKK6. It
plays important roles in cytokine and stress responses,
as well as in reactive oxygen species (ROS)-mediated
cellular responses. ASK1 is implicated in various
diseases mediated by oxidative stress including
inschemic heart disease, hypertension, vessel injury,
brain ischemia, Fanconi anemia, asthma, and pulmonary
edema, among others. ASK2 (also called MAPKKK6)
functions only in a heteromeric complex with ASK1, and
can activate ASK1 by direct phosphorylation. The
function of MAPKKK15 is still unknown.

proteins have not been fully elucidated. There is
evidence to suggest that MAPK cascades are involved in
plant stress responses. In Arabidopsis, MKK3 plays a
role in pathogen signaling, MKK2 is involved in cold and
salt stress signaling, MKK4/MKK5 participates in innate
immunity, and MKK7 regulates basal and systemic acquired

aPKCs only require phosphatidylserine (PS) for

to its role in transformed growth, PKC-iota also
promotes invasion, chemoresistance, and tumor cell
survival. Expression profiling of PKC-iota is a
prognostic marker of poor clinical outcome in several

superfamily that includes the catalytic domains of other
protein serine/threonine kinases (STKs), protein
tyrosine kinases (PTKs), RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase (PI3K). This family is composed of STKs, and
some dual-specificity PKs that phosphorylate both
threonine and tyrosine residues of target proteins. Most
members are kinases involved in mitogen-activated
protein kinase (MAPK) signaling cascades, acting as MAPK
kinases (MAPKKs), MAPK kinase kinases (MAPKKKs), or MAPK
kinase kinase kinases (MAP4Ks). The MAPK signaling
pathways are important mediators of cellular responses
to extracellular signals. The pathways involve a triple
kinase core cascade comprising of the MAPK, which is
phosphorylated and activated by a MAPKK, which itself is
phosphorylated and activated by a MAPKKK. Each MAPK
cascade is activated either by a small GTP-binding
protein or by an adaptor protein, which transmits the
signal either directly to a MAPKKK to start the triple
kinase core cascade or indirectly through a mediator
kinase, a MAP4K. Other STE family members include
p21-activated kinases (PAKs) and class III myosins,
among others. PAKs are Rho family GTPase-regulated
kinases that serve as important mediators in the
function of Cdc42 (cell division cycle 42) and Rac.
Class III myosins are motor proteins containing an
N-terminal kinase catalytic domain and a C-terminal
actin-binding domain, which can phosphorylate several
cytoskeletal proteins, conventional myosin regulatory
light chains, as well as autophosphorylate the
C-terminal motor domain. They play an important role in

point mutation in Nek8 causes cystic kidney disease in
mice that genetically resembles human autosomal
recessive polycystic kidney disease (ARPKD). Nek8 is
also associated with a rare form of juvenile renal
cystic disease, nephronophthisis type 9. It has been
suggested that a defect in the ciliary localization of
Nek8 contributes to the development of cysts manifested
by these diseases.

SH3 binding sites and a non-classical SH3 binding site
for PIX (PAK-interacting exchange factor). PAK3 is
highly expressed in the brain. It is implicated in
neuronal plasticity, synapse formation, dendritic spine
morphogenesis, cell cycle progression, neuronal
migration, and apoptosis. Inactivating mutations in the
PAK3 gene cause X-linked non-syndromic mental
retardation, the severity of which depends on the site
of the mutation.

(PKs), MAP kinase kinase (MAPKK) subfamily, fungal
PBS2-like proteins, catalytic (c) domain. PKs catalyze
the transfer of the gamma-phosphoryl group from ATP to

superfamily that includes the catalytic domains of other
protein serine/threonine kinases, protein tyrosine
kinases, RIO kinases, aminoglycoside phosphotransferase,
choline kinase, and phosphoinositide 3-kinase. The
mitogen-activated protein (MAP) kinase signaling
pathways are important mediators of cellular responses
to extracellular signals. The pathways involve a triple
kinase core cascade comprising of the MAP kinase (MAPK),
which is phosphorylated and activated by a MAPK kinase
(MAPKK or MKK), which itself is phosphorylated and
activated by a MAPK kinase kinase (MAPKKK or MKKK).
Members of this group include the MAPKKs Polymyxin B
resistance protein 2 (PBS2) from Saccharomyces
cerevisiae, Wis1 from Schizosaccharomyces pombe, and
related proteins. PBS2 and Wis1 are components of
stress-activated MAPK cascades in budding and fission
yeast, respectively. PBS2 is the specific activator of
the MAPK Hog1, which plays a central role in the
response of budding yeast to stress including exposure
to arsenite and hyperosmotic environments. Wis1
phosphorylates and activates the MAPK Sty1 (also called
Spc1 or Phh1), which stimulates a transcriptional
response to a wide range of cellular insults through the
bZip transcription factors Atf1, Pcr1, and Pap1.

MSKs are activated by two major signaling cascades, the
Ras-MAPK and p38 stress kinase pathways, in response to
various stimuli such as growth factors, hormones,
neurotransmitters, cellular stress, and pro-inflammatory

Serine/threonine kinases (STKs), p21-activated kinase
(PAK) subfamily, Group I, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to serine/threonine residues on protein substrates.
The PAK subfamily is part of a larger superfamily that
includes the catalytic domains of other protein STKs,
protein tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. PAKs are Rho family GTPase-regulated kinases
that serve as important mediators in the function of
Cdc42 (cell division cycle 42) and Rac. PAKs are
implicated in the regulation of many cellular processes
including growth factor receptor-mediated proliferation,
cell polarity, cell motility, cell death and survival,
and actin cytoskeleton organization. PAKs from higher
eukaryotes are classified into two groups (I and II),
according to their biochemical and structural features.
Group I PAKs, also called conventional PAKs, include
PAK1, PAK2, and PAK3. Group I PAKs contain a PBD
(p21-binding domain) overlapping with an AID
(autoinhibitory domain), a C-terminal catalytic domain,
SH3 binding sites and a non-classical SH3 binding site
for PIX (PAK-interacting exchange factor). They interact
with the SH3 domain containing proteins Nck, Grb2 and
PIX. Binding of group I PAKs to activated GTPases leads
to conformational changes that destabilize the AID,
allowing autophosphorylation and full activation of the
kinase domain. Known group I PAK substrates include
MLCK, Bad, Raf, MEK1, LIMK, Merlin, Vimentin, Myc,
Stat5a, and Aurora A, among others.

GRK1 to GRK7. GRK4 has a limited tissue distribution. It
is mainly found in the testis, but is also present in
the cerebellum and kidney. It is expressed as multiple
splice variants with different domain architectures. It
is post-translationally palmitoylated and localized in
the membrane. GRK4 polymorphisms are associated with
hypertension and salt sensitivity, as they cause
hyperphosphorylation, desensitization, and
internalization of the dopamine 1 (D1) receptor while
increasing the expression of the angiotensin II type 1
receptor. GRK4 plays a crucial role in the D1 receptor
regulation of sodium excretion and blood pressure.

MAST2 is also called MAST205. MAST kinases are
cytoskeletal associated kinases of unknown function that
are also expressed at neuromuscular junctions and

from the CAMK family, similar to 90 kDa ribosomal
protein S6 kinases (RSKs). MSKs are activated by two
major signaling cascades, the Ras-MAPK and p38 stress
kinase pathways, which trigger phosphorylation in the
activation loop (A-loop) of the CTD of MSK. The active
CTD phosphorylates the hydrophobic motif (HM) of NTD,
which facilitates the phosphorylation of the A-loop and
activates the NTD, which in turn phosphorylates
downstream targets. MSK1 plays a role in the regulation
of translational control and transcriptional activation.
It phosphorylates the transcription factors, CREB and
NFkappaB. It also phosphorylates the nucleosomal
proteins H3 and HMG-14. Increased phosphorylation of
MEK1 is associated with the development of cerebral
ischemic/hypoxic preconditioning.

phosphorylate and regulate G protein-coupled receptors
(GPCRs), the largest superfamily of cell surface
receptors which regulate some part of nearly all
physiological functions. Phosphorylated GPCRs bind to
arrestins, which prevents further G protein signaling
despite the presence of activating ligand. There are
seven types of GRKs, named GRK1 to GRK7. The beta-ARK
group is composed of GRK2, GRK3, and similar proteins.
GRK2 and GRK3 are both widely expressed in many tissues,
although GRK2 is present at higher levels. They contain
an N-terminal RGS homology (RH) domain, a central
catalytic domain, and C-terminal pleckstrin homology
(PH) domain that mediates PIP2 and G protein
betagamma-subunit translocation to the membrane. GRK2
(also called beta-ARK or beta-ARK1) is important in
regulating several cardiac receptor responses. It plays
a role in cardiac development and in hypertension.
Deletion of GRK2 in mice results in embryonic lethality,
caused by hypoplasia of the ventricular myocardium. GRK2
also plays important roles in the liver (as a regulator
of portal blood pressure), in immune cells, and in the
nervous system. Altered GRK2 expression has been
reported in several disorders including major
depression, schizophrenia, bipolar disorder, and
Parkinsonism.

(PI-PLC, EC 3.1.4.11)-delta1 isozymes. PI-PLC is a
signaling enzyme that hydrolyzes the membrane
phospholipids phosphatidylinositol-4,5-bisphosphate
(PIP2) to generate two important second messengers in
eukaryotic signal transduction cascades, Inositol
1,4,5-trisphosphate (InsP3) and diacylglycerol (DAG).
InsP3 triggers inflow of calcium from intracellular
stores, while DAG, together with calcium, activates
protein kinase C, which then phosphorylates other
molecules, leading to altered cellular activity. Calcium
is required for the catalysis. PLC-delta represents a
class of mammalian PI-PLC that has an N-terminal
pleckstrin homology (PH) domain, an array of EF hands, a
PLC catalytic core domain, and a C-terminal C2 domain.
This subfamily corresponds to the catalytic domain which
is a TIM barrel with two highly conserved regions (X and
Y) split by a highly degenerate linker sequence. There
are three PI-PLC-delta isozymes (1,3 and 4).
PI-PLC-delta1 is relatively well characterized. It is
activated by high calcium levels generated by other
PI-PLC family members, and therefore functions as a
calcium amplifier within the cell. Unlike PI-PLC-delta
4, PI-PLC-delta1 and 3 possess a putative nuclear export
sequence (NES) located in the EF-hand domain, which may
be responsible transporting PI-PLC-delta1and 3 from the
cell nucleus. Experiments show PI-PLC-delta1 is
essential for normal hair formation.

Serine/Threonine Kinase, Rho-associated coiled-coil
containing protein kinase 2. Serine/Threonine Kinases
(STKs), ROCK subfamily, ROCK2 (or ROK-alpha) isoform,
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The ROCK subfamily is
part of a larger superfamily that includes the catalytic
domains of other protein STKs, protein tyrosine kinases,
RIO kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. ROCK contains an
N-terminal extension, a catalytic kinase domain, and a
C-terminal extension, which contains a coiled-coil
region encompassing a Rho-binding domain (RBD) and a
pleckstrin homology (PH) domain. ROCK is auto-inhibited
by the RBD and PH domain interacting with the catalytic
domain, and is activated via interaction with Rho
GTPases. ROCK2 was the first identified target of
activated RhoA, and was found to play a role in stress
fiber and focal adhesion formation. It is prominently
expressed in the brain, heart, and skeletal muscles. It
is implicated in vascular and neurological disorders,
such as hypertension and vasospasm of the coronary and
cerebral arteries. ROCK2 is also activated by caspase-2
cleavage, resulting in thrombin-induced microparticle
generation in response to cell activation. Mice
deficient in ROCK2 show intrauterine growth retardation
and embryonic lethality because of placental
dysfunction.

lung, spleen, testes, and kidney. It mediates signaling
from Rho to the actin cytoskeleton. It is implicated in
the development of cardiac fibrosis, cardiomyocyte
apoptosis, and hyperglycemia. Mice deficient with ROCK1
display eyelids open at birth (EOB) and omphalocele
phenotypes due to the disorganization of actin filaments
in the eyelids and the umbilical ring.

Kinase, Protein Kinase B. Serine/Threonine Kinases
(STKs), Protein Kinase B (PKB) or Akt subfamily,
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The PKB subfamily is
part of a larger superfamily that includes the catalytic
domains of other protein STKs, protein tyrosine kinases,
RIO kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase (PI3K). There are
three PKB isoforms from different genes, PKB-alpha (or
Akt1), PKB-beta (or Akt2), and PKB-gamma (or Akt3). PKB
contains an N-terminal pleckstrin homology (PH) domain
and a C-terminal catalytic domain. It is activated
downstream of PI3K and plays important roles in diverse
cellular functions including cell survival, growth,
proliferation, angiogenesis, motility, and migration.
PKB also has a central role in a variety of human
cancers, having been implicated in tumor initiation,
progression, and metastasis.

>gnl|CDD|239045 cd02130, PA_ScAPY_like, PA_ScAPY_like: Protease-associated domain
containing proteins like Saccharomyces cerevisiae
aminopeptidase Y (ScAPY). This group contains various PA
domain-containing proteins similar to the S. cerevisiae
APY, including Trichophyton rubrum leucine
aminopeptidase 1(LAP1). Proteins in this group belong to
the peptidase M28 family. ScAPY hydrolyzes amino
acid-4-methylcoumaryl-7-amides (MCAs). ScAPY more
rapidly hydrolyzes dipeptidyl-MCAs. Hydrolysis of amino
acid-MCAs or dipeptides is stimulated by Co2+ while the
hydrolysis of dipeptidyl-MCAs, tripeptides, and longer
peptides is inhibited by Co2+. ScAPY is vacuolar and is
activated by proteolytic processing. LAP1 is a secreted
leucine aminopeptidase. The significance of the PA
domain to these proteins has not been ascertained. It
may be a protein-protein interaction domain. At
peptidase active sites, the PA domain may participate in
substrate binding and/or promoting conformational
changes, which influence the stability and accessibility
of the site to substrate.
