>gnl|CDD|173623 cd00180, PKc, Catalytic domain of Protein Kinases. Protein
Kinases (PKs), catalytic (c) domain. PKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
serine/threonine or tyrosine residues on protein
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.

phosphorylates the activation loop of AGC kinases that
are regulated by PI3K such as PKB, SGK, and PKC, among
others, and is crucial for their activation. Thus, it
contributes in regulating many processes including
metabolism, growth, proliferation, and survival. PDK1
also has the ability to autophosphorylate and is
constitutively active in mammalian cells. PDK1 is
essential for normal embryo development and is
important in regulating cell volume.

>gnl|CDD|173660 cd05123, STKc_AGC, Catalytic domain of AGC family Protein
Serine/Threonine Kinases. Serine/Threonine Kinases
(STKs), AGC (Protein Kinases A, G and C) family,
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The AGC family 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). Members of this
family include cAMP-dependent Protein Kinase (PKA),
cGMP-dependent Protein Kinase (PKG), Protein Kinase C
(PKC), Protein Kinase B (PKB), G protein-coupled
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.

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 MAPKKs from plants, kinetoplastids,
alveolates, and mycetozoa. The MAPKK, LmxPK4, from
Leishmania mexicana, is important in differentiation
and virulence. Dictyostelium discoideum MEK1 is
required for proper chemotaxis. MEK1 null mutants
display severe defects in cell polarization and
directional movement. Plants contain multiple MAPKKs
like other eukaryotes. The Arabidopsis genome encodes
for 10 MAPKKs while poplar and rice contain 13 MAPKKs
each. The functions of these 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
resistance.

stress-activated kinase (MSK) subfamily, N-terminal
catalytic (c) domain. STKs catalyze the transfer of the

part of a larger superfamily that includes the
catalytic domains of other protein STKs, protein

kinase domain (NTD) from the AGC family and a
C-terminal kinase domain (CTD) 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, in response to
various stimuli such as growth factors, hormones,
neurotransmitters, cellular stress, and
pro-inflammatory cytokines. This triggers
phosphorylation in the activation loop (A-loop) of the
CTD of MSK. The active CTD phosphorylates the
hydrophobic motif (HM) in the C-terminal extension of
NTD, which facilitates the phosphorylation of the
A-loop and activates the NTD, which in turn
phosphorylates downstream targets. MSKs are
predominantly nuclear proteins. They are widely
expressed in many tissues including heart, brain, lung,
liver, kidney, and pancreas. There are two isoforms of
MSK, called MSK1 and MSK2.

Drosophila Hippo and Dictyostelium discoideum Krs1
(kinase responsive to stress 1). MST1/2 and Hippo are
involved in a conserved pathway that governs cell
contact inhibition, organ size control, and tumor
development. MST1 activates the mitogen-activated
protein kinases (MAPKs) p38 and c-Jun N-terminal kinase
(JNK) through MKK7 (a MAPK kinase) and MEKK1 (a MAPK
kinase kinase) by acting as a MAPK kinase kinase kinase
(MAPKKKK). Activation of JNK by MST1 leads to caspase
activation and apoptosis. MST1 has also been implicated
in cell proliferation and differentiation. Krs1 may
regulate cell growth arrest and apoptosis in response
to cellular stress.

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.

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.

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 Pek1/Skh1 from
Schizosaccharomyces pombe and MKK2 from Saccharomyces
cerevisiae, and related proteins. Both fission yeast
Pek1 and baker's yeast MKK2 are components of the cell
integrity MAPK pathway. In fission yeast, Pek1
phosphorylates and activates the MAPK Pmk1/Spm1 and is
regulated by the MAPKKK Mkh1. In baker's yeast, the
pathway involves the MAPK Slt2, the MAPKKs MKK1 and
MKK2, and the MAPKKK Bck1. The cell integrity MAPK
cascade is activated by multiple stress conditions, and
is essential in cell wall construction, morphogenesis,
cytokinesis, and ion homeostasis.

a Rho-binding domain (RBD), a zinc finger, and a
pleckstrin homology (PH) domain, in addition to other
motifs. CRIK, an effector of the small GTPase Rho,
plays an important function during cytokinesis and
affects its contractile process. CRIK-deficient mice
show severe ataxia and epilepsy as a result of abnormal
cytokinesis and massive apoptosis in neuronal

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.

classified into three groups (classical, atypical, and
novel) depending on their mode of activation and the
structural characteristics of their regulatory domain.
aPKCs only require phosphatidylserine (PS) for
activation. They contain a C2-like region, instead of a
calcium-binding (C2) region found in classical PKCs, in
their regulatory domain. There are two aPKC isoforms,
zeta and iota. aPKCs are involved in many cellular
functions including proliferation, migration,
apoptosis, polarity maintenance and cytoskeletal

Drosophila class III myosin, called NinaC (Neither
inactivation nor afterpotential protein C), is critical
in normal adaptation and termination of photoresponse.
Vertebrates contain two isoforms of class III myosin,
IIIA and IIIB. This subfamily also includes mammalian
NIK-like embryo-specific kinase (NESK), Traf2- and
Nck-interacting kinase (TNIK), mitogen-activated
protein kinase (MAPK) kinase kinase kinase 4 (MAPKKKK4
or MAP4K4) and MAPKKKK6 (or MAP4K6). MAP4Ks are
involved in some MAPK signaling pathways by activating
a MAPK kinase kinase (MAPKKK or MAP3K or MKKK). 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 MAP3K to start the triple
kinase core cascade or indirectly through a mediator
kinase, a MAP4K. MAPK signaling cascades are important
in mediating cellular responses to extracellular
signals.

kinase 1 (HPK1), is a hematopoietic-specific STK
involved in many cellular signaling cascades including
MAPK, antigen receptor, apoptosis, growth factor, and
cytokine signaling. It participates in the regulation
of T cell receptor signaling and T cell-mediated immune
responses. MAP4K2 was referred to as germinal center
(GC) kinase because of its preferred location in GC B
cells. MAP4K3 plays a role in the nutrient-responsive
pathway of mTOR (mammalian target of rapamycin)
signaling. It is required in the activation of S6
kinase by amino acids and for the phosphorylation of
the mTOR-regulated inhibitor of eukaryotic initiation
factor 4E. MAP4K5, also called germinal center

cell-cycle progression, transcription, and neuronal
function. CDK4 and CDK6 partner with D-type cyclins to
regulate the early G1 phase of the cell cycle. They are
the first kinase activated by mitogenic signals to
release cells from the G0 arrested state. CDK4 and CDK6
are both expressed ubiquitously, associate with all
three D cyclins (D1, D2 and D3), and phosphorylate the
retinoblastoma (pRb) 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.

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.

NAD-dependent formate dehydrogenase (FDH) catalyzes the
NAD+-dependent oxidation of a formate anion to carbon
dioxide coupled with the reduction of NAD+ to NADH.
Formate/glycerate and related dehydrogenases of the
D-specific 2-hydroxy acid dehydrogenase family have 2
highly similar subdomains of the alpha/beta form, with
NAD binding occurring in the cleft between subdomains.
NAD contacts are primarily to the Rossmann-fold
NAD-binding domain which is inserted within the linear
sequence of the more diverse flavodoxin-like catalytic
subdomain. Some related proteins have similar structural
subdomain but with a tandem arrangement of the catalytic
and NAD-binding subdomains in the linear sequence. FDHs
of this family contain no metal ions or prosthetic
groups. Catalysis occurs though direct transfer of the
hydride ion to NAD+ without the stages of acid-base
catalysis typically found in related dehydrogenases.
FDHs are found in all methylotrophic microorganisms in
energy production from C1 compounds such as methanol,
and in the stress responses of plants. NAD-dependent FDH
is useful in cofactor regeneration in asymmetrical
biocatalytic reduction processes, where FDH irreversibly
oxidizes formate to carbon dioxide, while reducing the
oxidized form of the cofactor to the reduced form.

N-terminal regulatory (NTR) domain and an insert within
the catalytic domain that contains an auto-inhibitory
sequence. Like many other AGC kinases, NDR kinase
requires phosphorylation at two sites, the activation
loop (A-loop) and the hydrophobic motif (HM), for
activity. Higher eukaryotes contain two NDR isoforms,
NDR1 and NDR2. Both isoforms play a role in proper
centrosome duplication. NDR1 is highly expressed in
thymus, muscle, lung and spleen. It is not an essential
protein because mice deficient of NDR1 remain viable
and fertile. However, these mice develop T-cell
lymphomas and appear to be hypersenstive to
carcinogenic treatment. NDR1 appears to act as a tumor
suppressor. NDR1 is also called STK38.

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. GRK3 (also known as
beta-adrenergic receptor kinase 2) is widely expressed
in many tissues. GRK3-deficient mice show a lack of
olfactory receptor desensitization and altered
regulation of the M2 muscarinic airway. GRK3 is
involved in modulating the cholinergic response of
airway smooth muscles. It also plays a role in dopamine
receptor regulation. GRK3 promoter polymorphisms may be
associated with bipolar disorder.

required by fission yeast for polarizing the tips of
actin cytoskeleton and is involved in cell growth, cell
separation, cell morphology and cell-cycle progression.
Sid1 is a component in the septation initiation network
(SIN) signaling pathway, and plays a role in

required for spore wall formation. MST4 plays a role in
mitogen-activated protein kinase (MAPK) signaling
during cytoskeletal rearrangement, morphogenesis, and

mitogen-activated protein kinase (MAPK) kinase kinase
(MAPKKK or MKKK or MAP3K), that phosphorylates and
activates 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. MEKK4
activates the c-Jun N-terminal kinase (JNK) and p38
MAPK signaling pathways by directly activating their
respective MAPKKs, MKK4/MKK7 and MKK3/MKK6. JNK and p38
are collectively known as stress-activated MAPKs, as
they are activated in response to a variety of
environmental stresses and pro-inflammatory cytokines.
MEKK4 also plays roles in the re-polarization of the
actin cytoskeleton in response to osmotic stress, in
the proper closure of the neural tube, in
cardiovascular development, and in immune responses.

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.
