>gnl|CDD|173687 cd05596, STKc_ROCK, Catalytic domain of the Protein
Serine/Threonine Kinase, Rho-associated coiled-coil
containing protein kinase. Serine/Threonine Kinases
(STKs), Rho-associated coiled-coil containing protein
kinase (ROCK) subfamily, 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 is also
referred to as Rho-associated kinase or simply as Rho
kinase. It contains an N-terminal extension, a
catalytic kinase domain, and a long 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. It is activated via interaction with Rho
GTPases and is involved in many cellular functions
including contraction, adhesion, migration, motility,
proliferation, and apoptosis. The ROCK subfamily
consists of two isoforms, ROCK1 and ROCK2, which may be
functionally redundant in some systems, but exhibit
different tissue distributions. Both isoforms are
ubiquitously expressed in most tissues, but ROCK2 is
more prominent in brain and skeletal muscle while ROCK1
is more pronounced in the liver, testes, and kidney.
Studies in knockout mice result in different
phenotypes, suggesting that the two isoforms do not
compensate for each other during embryonic development.

Serine/Threonine Kinases (STKs), Nuclear Dbf2-Related
(NDR) kinase subfamily, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine residues on protein
substrates. The NDR 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. NDR kinase
contains an 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. NDR kinases regulate mitosis, cell
growth, embryonic development, and neurological
processes. They are also required for proper centrosome
duplication. Higher eukaryotes contain two NDR
isoforms, NDR1 and NDR2. This subfamily also contains
fungal NDR-like kinases.

protein kinase-like Protein Serine/Threonine Kinases.
Serine/Threonine Kinases (STKs), Myotonic Dystrophy
protein kinase (DMPK)-like subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The DMPK-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. The DMPK-like subfamily is
composed of DMPK and DMPK-related cell division control
protein 42 (Cdc42) binding kinase (MRCK). Three
isoforms of MRCK are known, named alpha, beta and
gamma. The DMPK gene is implicated in myotonic
dystrophy 1 (DM1), an inherited multisystemic disorder
with symptoms that include muscle hyperexcitability,
progressive muscle weakness and wasting, cataract
development, testicular atrophy, and cardiac conduction
defects. The genetic basis for DM1 is the mutational
expansion of a CTG repeat in the 3'-UTR of DMPK. DMPK
is expressed in skeletal and cardiac muscles, and in
central nervous tissues. The functional role of DMPK is
not fully understood. It may play a role in the signal
transduction and homeostasis of calcium. MRCK is
activated via interaction with the small GTPase Cdc42.
MRCK/Cdc42 signaling mediates myosin-dependent cell
motility. MRCKgamma is expressed in heart and skeletal
muscles, unlike MRCKalpha and MRCKbeta, which are
expressed ubiquitously.

include ROCK and ROCK-like proteins such as DMPK, MRCK,
and CRIK, as well as NDR and NDR-like proteins such as
LATS, CBK1 and Sid2p. ROCK and CRIK are effectors of
the small GTPase Rho, while MRCK is an effector of the
small GTPase Cdc42. NDR and NDR-like kinases contain an
N-terminal regulatory (NTR) domain and an insert within
the catalytic domain that contains an auto-inhibitory

NIMA is essential for mitotic entry and progression
through mitosis, and its degradation is essential for
mitotic exit. NIMA is involved in nuclear membrane
fission. Vertebrate Nek2 is a cell cycle-regulated STK,
localized in centrosomes and kinetochores, that
regulates centrosome splitting at the G2/M phase. It
also interacts with other mitotic kinases such as
Polo-like kinase 1 and may play a role in spindle

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.

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.

functions in the MMS2 error-free branch of the PRR
pathway in the maintenance and repair of stalled
replication forks. Studies also suggest that EXO1 plays
both structural and catalytic roles during MMR-mediated
mutation avoidance. EXO1 belongs to the FEN1-EXO1-like

Vertebrate members contain an N-terminal catalytic

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

structural characteristics of their regulatory domain.
PKCs undergo three phosphorylations in order to take
mature forms. In addition, cPKCs depend on calcium, DAG
(1,2-diacylglycerol), and in most cases,
phosphatidylserine (PS) for activation. cPKCs contain a
calcium-binding C2 region in their regulatory domain.
There are four cPKC isoforms, named alpha, betaI,

MSKs are activated by two major signaling cascades, the
