protein kinase 3-like Protein Serine/Threonine Kinases.
Serine/threonine kinases (STKs), mammalian Ste20-like
protein kinase 3 (MST3)-like subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The MST3-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 MST3, MST4,
STK25, Schizosaccharomyces pombe Nak1 and Sid1,
Saccharomyces cerevisiae sporulation-specific protein 1
(SPS1), and related proteins. Nak1 is 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
cytokinesis. SPS1 plays a role in regulating proteins
required for spore wall formation. MST4 plays a role in
mitogen-activated protein kinase (MAPK) signaling during
cytoskeletal rearrangement, morphogenesis, and
apoptosis. MST3 phosphorylates the STK NDR and may play
a role in cell cycle progression and cell morphology.
STK25 may play a role in the regulation of cell
migration and polarization.

protein 7-like Protein Serine/Threonine Kinases.
Serine/threonine kinases (STKs), (Cdc7)-like subfamily,
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The Cdc7-like subfamily
is part of a larger superfamily that includes the
catalytic domains of other protein STKs, protein
tyrosine kinases, RIO kinases, aminoglycoside

3-kinase. Members of this subfamily include
Schizosaccharomyces pombe Cdc7, Saccharomyces cerevisiae
Cdc15, Arabidopsis thaliana mitogen-activated protein
kinase (MAPK) kinase kinase (MAPKKK) epsilon, and
related proteins. 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. Fission yeast Cdc7
is essential for cell division by playing a key role in
the initiation of septum formation and cytokinesis.
Budding yeast Cdc15 functions to coordinate mitotic exit
with cytokinesis. Arabidopsis MAPKKK epsilon is required
for pollen development in the plasma membrane.

dual-specificity MAP kinase kinases and similar
proteins. Protein kinases (PKs), MAP kinase kinase
(MAPKK) subfamily, Plant MAPKKs and similar proteins,
catalytic (c) domain. PKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine or
tyrosine residues on protein substrates. The MAPKK
subfamily is part of a larger 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 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.

kinase, and phosphoinositide 3-kinase. This subfamily is
composed of plant mitogen-activated protein kinase
(MAPK) kinase kinases (MAPKKKs or MKKKs or MAP3Ks)
including Arabidopsis thaliana MEKK1 and MAPKKK3. MEKK1
is a MAPKKK 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. Arabidopsis thaliana
MEKK1 activates MPK4, a MAPK that regulates systemic
acquired resistance. MEKK1 also participates in the
regulation of temperature-sensitive and tissue-specific
cell death.

3-kinase. STK25 is also called Ste20/oxidant stress
response kinase 1 (SOK1) or yeast Sps1/Ste20-related
kinase 1 (YSK1). STK25 is localized in the Golgi
apparatus through its interaction with the Golgi matrix
protein GM130. It may play a role in the regulation of
cell migration and polarization. STK25 binds and
phosphorylates CCM3 (cerebral cavernous malformation 3),
also called PCD10 (programmed cell death 10), and may
play a role in apoptosis. Human STK25 is a candidate
gene responsible for pseudopseudohypoparathyroidism

related proteins including 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

Serine/threonine kinases (STKs), MAP/ERK kinase kinase 4
(MEKK4) subfamily, catalytic (c) domain. STKs catalyze
the transfer of the gamma-phosphoryl group from ATP 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.

>gnl|CDD|173659 cd05122, PKc_STE, Catalytic domain of STE family Protein Kinases.
Protein Kinases (PKs), STE family, catalytic (c) domain.
PKs catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine or tyrosine residues on
protein substrates. The STE family is part of a larger
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
maintaining the structural integrity of photoreceptor
cell microvilli.

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. PAK deregulation is
associated with tumor development. PAKs from higher
eukaryotes are classified into two groups (I and II),
according to their biochemical and structural features.
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). Group II PAKs contain a PBD and a
catalytic domain, but lack other motifs found in group I
PAKs. Since group II PAKs do not contain an obvious AID,
they may be regulated differently from group I PAKs.
Group I PAKs interact with the SH3 containing proteins
Nck, Grb2 and PIX; no such binding has been demonstrated
for group II PAKs.

signaling during cytoskeletal rearrangement,
morphogenesis, and apoptosis. It influences cell growth
and transformation by modulating the extracellular
signal-regulated kinase (ERK) pathway. MST4 may also
play a role in tumor formation and progression. It
localizes in the Golgi apparatus by interacting with the
Golgi matrix protein GM130 and may play a role in cell
migration.

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.

contain an N-terminal catalytic domain and a C-terminal
citron homology (CNH) regulatory domain, similar to
MAP4K4/6. MAP4Ks are involved in some MAPK signaling
pathways that are important in mediating cellular
responses to extracellular signals 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. MAP4K1, also called haematopoietic
progenitor 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

proteins with an N-terminal kinase catalytic domain and
a C-terminal actin-binding motor domain. Class III
myosins are present in the photoreceptors of
invertebrates and vertebrates and in the auditory hair
cells of mammals. The kinase domain of myosin III can
phosphorylate several cytoskeletal proteins,
conventional myosin regulatory light chains, and can
autophosphorylate the C-terminal motor domain. Myosin
III may play an important role in maintaining the
structural integrity of photoreceptor cell microvilli.
It may also function as a cargo carrier during
light-dependent translocation, in photoreceptor cells,
of proteins such as transducin and arrestin. The
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

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.

transcription, and neuronal function. This subfamily is
composed of CDKL1-5 and similar proteins. Some CDKLs,
like CDKL1 and CDKL3, may be implicated in
transformation and others, like CDKL3 and CDKL5, are
associated with mental retardation when impaired. CDKL2
plays a role in learning and memory.

>gnl|CDD|99871 cd06118, citrate_synt_like_1, Citrate synthase (CS) catalyzes the
condensation of acetyl coenzyme A (AcCoA) and
oxalacetate (OAA) to form citrate and coenzyme A (CoA),
the first step in the oxidative citric acid cycle (TCA
or Krebs cycle). Peroxisomal CS is involved in the
glyoxylate cycle. This group also includes CS proteins
which functions as a 2-methylcitrate synthase (2MCS).
2MCS catalyzes the condensation of propionyl-CoA (PrCoA)
and OAA to form 2-methylcitrate and CoA during
propionate metabolism. This group contains proteins
which functions exclusively as either a CS or a 2MCS, as
well as those with relaxed specificity which have dual
functions as both a CS and a 2MCS. The overall CS
reaction is thought to proceed through three partial
reactions and involves both closed and open
conformational forms of the enzyme: a) the carbanion or
equivalent is generated from AcCoA by base abstraction
of a proton, b) the nucleophilic attack of this
carbanion on OAA to generate citryl-CoA, and c) the
hydrolysis of citryl-CoA to produce citrate and CoA.
There are two types of CSs: type I CS and type II CSs.
Type I CSs are found in eukarya, gram-positive bacteria,
archaea, and in some gram-negative bacteria and are
homodimers with both subunits participating in the
active site. Type II CSs are unique to gram-negative
bacteria and are homohexamers of identical subunits
(approximated as a trimer of dimers). Some type II CSs
are strongly and specifically inhibited by NADH through
an allosteric mechanism.

(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. MEKK1 activates the extracellular
signal-regulated kinase 1/2 (ERK1/2) and c-Jun
N-terminal kinase (JNK) pathways by activating their
respective MAPKKs, MEK1/2 and MKK4/MKK7, respectively.
MEKK1 is important in regulating cell survival and
apoptosis. MEKK1 also plays a role in cell migration,
tissue maintenance and homeostasis, and wound healing.

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.

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). MKK4 is a dual-specificity PK that
phosphorylates and activates the downstream targets,
c-Jun N-terminal kinase (JNK) and p38 MAPK, on specific
threonine and tyrosine residues. 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. Their
activation is associated with the induction of cell
death. Mice deficient in MKK4 die during embryogenesis
and display anemia, severe liver hemorrhage, and
abnormal hepatogenesis. MKK4 may also play roles in the
immune system and in cardiac hypertrophy. It plays a
major role in cancer as a tumor and metastasis
suppressor. Under certain conditions, MKK4 is
pro-oncogenic.
