Protein Kinases, MAP kinase kinases 3 and 6. Protein
kinases (PKs), MAP kinase kinase 3 (MKK3) and MKK6
subfamily, catalytic (c) domain. PKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
serine/threonine or tyrosine residues on protein
substrates. The MKK3 and MKK6 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 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). MKK3 and MKK6 are
dual-specificity PKs that phosphorylate and activate
their downstream target, p38 MAPK, on specific
threonine and tyrosine residues. MKK3/6 plays roles in
the regulation of cell cycle progression, cytokine- and
stress-induced apoptosis, oncogenic transformation, and
adult tissue regeneration. In addition, MKK6 plays a
critical role in osteoclast survival in inflammatory
disease while MKK3 is associated with tumor invasion,
progression, and poor patient survival in glioma.

(PKs), MAP kinase kinase 4 (MKK4) subfamily, catalytic
(c) domain. PKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine or

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.

phosphorylate their downstream targets, MAPKs, at
specific threonine and tyrosine residues. There are
three MAPK subfamilies: extracellular signal-regulated
kinase (ERK), c-Jun N-terminal kinase (JNK), and p38.
In mammalian cells, there are seven MAPKKs (named
MKK1-7) and 20 MAPKKKs. Each MAPK subfamily can be
activated by at least two cognate MAPKKs and by
multiple MAPKKKs.

>gnl|CDD|132949 cd06618, PKc_MKK7, Catalytic domain of the dual-specificity Protein
Kinase, MAP kinase kinase 7. Protein kinases (PKs), MAP
kinase kinase 7 (MKK7) subfamily, catalytic (c) domain.
PKs catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine or tyrosine residues on
protein substrates. The MKK7 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 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).
MKK7 is a dual-specificity PK that phosphorylates and
activates its downstream target, c-Jun N-terminal kinase
(JNK), on specific threonine and tyrosine residues.
Although MKK7 is capable of dual phosphorylation, it
prefers to phosphorylate the threonine residue of JNK.
Thus, optimal activation of JNK requires both MKK4 (not
included in this subfamily) and MKK7. MKK7 is primarily
activated by cytokines. MKK7 is essential for liver
formation during embryogenesis. It plays roles in G2/M
cell cycle arrest and cell growth. In addition, it is
involved in the control of programmed cell death, which
is crucial in oncogenesis, cancer chemoresistance, and
antagonism to TNFalpha-induced killing, through its
inhibition by Gadd45beta and the subsequent suppression
of the JNK cascade.

(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

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.

pombe, FUZ7 from Ustilago maydis, and related proteins.
Byr1 phosphorylates its downstream target, the MAPK
Spk1, and is regulated by the MAPKKK Byr2. The Spk1
cascade is pheromone-responsive and is essential for
sporulation and sexual differentiation in fission
yeast. FUZ7 phosphorylates and activates its target,
the MAPK Crk1, which is required in mating and
virulence in U. maydis.

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

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.

cascade comprising the MAP kinase (MAPK), which is
phosphorylated and activated by a MAPK kinase (MAPKK or

dual-specificity PKs that phosphorylate and activate
the downstream targets, ERK(extracellular
signal-regulated kinase) 1 and ERK2, on specific
threonine and tyrosine residues. The ERK cascade starts
with extracellular signals including growth factors,
hormones, and neurotransmitters, which act through
receptors and ion channels to initiate intracellular
signaling that leads to the activation at the MAPKKK
(Raf-1 or MOS) level, which leads to the transmission
of signals to MEK1/2, and finally to ERK1/2. The ERK
cascade plays an important role in cell proliferation,
differentiation, oncogenic transformation, and cell
cycle control, as well as in apoptosis and cell
survival under certain conditions. This cascade has
also been implicated in synaptic plasticity, migration,
morphological determination, and stress response
immunological reactions. Gain-of-function mutations in
genes encoding ERK cascade proteins, including MEK1/2,
cause cardiofaciocutaneous (CFC) syndrome, a condition
leading to multiple congenital anomalies and mental
retardation in patients.

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.

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.

and tyrosine residues. MKK5 is activated by MEKK2 and
MEKK3 in response to mitogenic and stress stimuli. The
ERK5 cascade promotes cell proliferation,
differentiation, neuronal survival, and
neuroprotection. This cascade plays an essential role
in heart development. Mice deficient in either ERK5 or
MKK5 die around embryonic day 10 due to cardiovascular
defects including underdevelopment of the myocardium.
In addition, MKK5 is associated with metastasis and
unfavorable prognosis in prostate cancer.

MAP4K3, MAP4K1, MAP4K2, MAP4K5, and related proteins.
Vertebrate members 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
kinase-related enzyme (GCKR), has been shown to
activate the MAPK c-Jun N-terminal kinase (JNK).

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.

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

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.

This PTKc family is part of a larger superfamily that

serine/threonine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. They can
be classified into receptor and non-receptor tyr
kinases. PTKs play important roles in many cellular
processes including, lymphocyte activation, epithelium
growth and maintenance, metabolism control,
organogenesis regulation, survival, proliferation,
differentiation, migration, adhesion, motility, and
morphogenesis. Receptor tyr kinases (RTKs) are integral
membrane proteins which contain an extracellular
ligand-binding region, a transmembrane segment, and an
intracellular tyr kinase domain. RTKs are usually
activated through ligand binding, which causes
dimerization and autophosphorylation of the
intracellular tyr kinase catalytic domain, leading to
intracellular signaling. Some RTKs are orphan receptors
with no known ligands. Non-receptor (or cytoplasmic)
tyr kinases are distributed in different intracellular
compartments and are usually multi-domain proteins
containing a catalytic tyr kinase domain as well as
various regulatory domains such as SH3 and SH2. PTKs
are usually autoinhibited and require a mechanism for
activation. In many PTKs, the phosphorylation of tyr
residues in the activation loop is essential for
optimal activity. Aberrant expression of PTKs is
associated with many development abnormalities and
cancers.

serine/threonine kinases, RIO kinases, and
phosphoinositide 3-kinase (PI3K). The InsR subfamily is
composed of InsR, Insulin-like Growth Factor-1 Receptor
(IGF-1R), and similar proteins. PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. InsR and
IGF-1R are receptor tyr kinases (RTKs) composed of two
alphabeta heterodimers. Binding of the ligand (insulin,
IGF-1, or IGF-2) to the extracellular alpha subunit
activates the intracellular tyr kinase domain of the
transmembrane beta subunit. Receptor activation leads
to autophosphorylation, stimulating downstream kinase
activities, which initiate signaling cascades and
biological function. InsR and IGF-1R, which share 84%
sequence identity in their kinase domains, display
physiologically distinct yet overlapping functions in
cell growth, differentiation, and metabolism. InsR
activation leads primarily to metabolic effects while
IGF-1R activation stimulates mitogenic pathways. In
cells expressing both receptors, InsR/IGF-1R hybrids
are found together with classical receptors. Both
receptors can interact with common adaptor molecules
such as IRS-1 and IRS-2.

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.

kinase kinase kinase kinase 5. Serine/threonine
kinases (STKs), mitogen-activated protein kinase (MAPK)
kinase kinase kinase 5 (MAPKKKK5 or MAP4K5) subfamily,
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The MAP4K5 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. Members of this subfamily
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. MAP4K5, also called germinal center
kinase-related enzyme (GCKR), has been shown to
activate the MAPK c-Jun N-terminal kinase (JNK). MAP4K5
also facilitates Wnt signaling in B cells, and may
therefore be implicated in the control of cell fate,
proliferation, and polarity.

>gnl|CDD|132940 cd06609, STKc_MST3_like, Catalytic domain of Mammalian Ste20-like
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.
