>gnl|CDD|119428 cd05168, PI4Kc_III_beta, Phosphoinositide 4-kinase (PI4K), Type
III, beta isoform, catalytic domain; The PI4K catalytic
domain family is part of a larger superfamily that
includes the catalytic domains of other kinases such as
the typical serine/threonine/tyrosine protein kinases
(PKs), aminoglycoside phosphotransferase, choline
kinase, and RIO kinases. PI4Ks catalyze the transfer of
the gamma-phosphoryl group from ATP to the 4-hydroxyl of
the inositol ring of D-myo-phosphatidylinositol (PtdIns)
to generate PtdIns(4)P, the major precursor in the
synthesis of other phosphoinositides including
PtdIns(4,5)P2, PtdIns(3,4)P2, and PtdIns(3,4,5)P3. Two
isoforms of type III PI4K, alpha and beta, exist in most
eukaryotes. PI4KIIIbeta (also called Pik1p in yeast) is
a 110 kDa protein that is localized to the Golgi and the
nucleus. It is required for maintaining the structural
integrity of the Golgi complex (GC), and is a key
regulator of protein transport from the GC to the plasma
membrane. PI4KIIIbeta also functions in the genesis,
transport, and exocytosis of synaptic vesicles. The
Drosophila PI4KIIIbeta is essential for cytokinesis
during spermatogenesis.

isoforms of type III PI4K, alpha and beta, exist in most
eukaryotes. PI4KIIIalpha is a 220 kDa protein found in
the plasma membrane and the endoplasmic reticulum (ER).
The role of PI4KIIIalpha in the ER remains unclear. In
the plasma membrane, it provides PtdIns(4)P, which is
then converted by PI5Ks to PtdIns(4,5)P2, an important
signaling molecule. Vertebrate PI4KIIIalpha is also part
of a signaling complex associated with P2X7 ion
channels. The yeast homolog, Stt4p, is also important in
regulating the conversion of phosphatidylserine to
phosphatidylethanolamine at the ER and Golgi interface.
Mammalian PI4KIIIalpha is highly expressed in the
nervous system.

Phosphoinositide 3-kinase isoforms participate in a
variety of processes, including cell motility, the Ras
pathway, vesicle trafficking and secretion, and
apoptosis. These homologues may be either lipid kinases
and/or protein kinases: the former phosphorylate the
3-position in the inositol ring of inositol
phospholipids. The ataxia telangiectesia-mutated gene
produced, the targets of rapamycin (TOR) and the
DNA-dependent kinase have not been found to possess
lipid kinase activity. Some of this family possess PI-4
kinase activities.

The PI3K catalytic domain family is part of a larger
superfamily that includes the catalytic domains of other
kinases such as the typical serine/threonine/tyrosine
protein kinases (PKs), aminoglycoside
phosphotransferase, choline kinase, and RIO kinases.
PI3Ks catalyze the transfer of the gamma-phosphoryl
group from ATP to the 3-hydroxyl of the inositol ring of
D-myo-phosphatidylinositol (PtdIns) or its derivatives.
PI3Ks play an important role in a variety of fundamental
cellular processes, including cell motility, the Ras
pathway, vesicle trafficking and secretion, immune cell
activation and apoptosis. They can be divided into three
main classes (I, II, and III), defined by their
substrate specificity, regulation, and domain structure.
Class I PI3Ks are the only enzymes capable of converting
PtdIns(4,5)P2 to the critical second messenger
PtdIns(3,4,5)P3. Class I enzymes are heterodimers and
exist in multiple isoforms consisting of one catalytic
subunit (out of four isoforms) and one of several
regulatory subunits. Class II PI3Ks comprise three
catalytic isoforms that do not associate with any
regulatory subunits. They selectively use PtdIns as a
susbtrate to produce PtsIns(3)P.

domain. They phosphorylate only the substrate PtdIns.
They interact with a regulatory subunit, Vps15, to form
a membrane-associated complex. Class III PI3Ks are
involved in protein and vesicular trafficking and
sorting, autophagy, trimeric G-protein signaling, and
phagocytosis.

PtdIns as a substrate to produce PtdIns(3)P, but can
also phosphorylate PtdIns(4)P. They function as monomers
and do not associate with any regulatory subunits. Class
II enzymes contain an N-terminal Ras binding domain, a
lipid binding C2 domain, a PI3K homology domain of
unknown function, an ATP-binding cataytic domain, a Phox

beta isoform, catalytic domain; The PI3K catalytic
domain family is part of a larger superfamily that
includes the catalytic domains of other kinases such as
the typical serine/threonine/tyrosine protein kinases
(PKs), aminoglycoside phosphotransferase, choline
kinase, and RIO kinases. PI3Ks catalyze the transfer of
the gamma-phosphoryl group from ATP to the 3-hydroxyl of
the inositol ring of D-myo-phosphatidylinositol (PtdIns)
or its derivatives. PI3Ks can be divided into three main
classes (I, II, and III), defined by their substrate
specificity, regulation, and domain structure. Class I
PI3Ks are the only enzymes capable of converting
PtdIns(4,5)P2 to the critical second messenger
PtdIns(3,4,5)P3. Class I enzymes are heterodimers and
exist in multiple isoforms consisting of one catalytic
subunit (out of four isoforms) and one of several
regulatory subunits. They are further classified into
class IA (alpha, beta and delta) and IB (gamma). Class
IA enzymes contain an N-terminal p85 binding domain, a
Ras binding domain, a lipid binding C2 domain, a PI3K
homology domain of unknown function, and a C-terminal
ATP-binding cataytic domain. They associate with a
regulatory subunit of the p85 family and are activated
by tyrosine kinase receptors. In addition, PI3Kbeta can
also be activated by G-protein-coupled receptors.
Deletion of PI3Kbeta in mice results in early lethality
at around day three of development. PI3Kbeta plays an
important role in regulating sustained integrin
activation and stable platelet agrregation, especially
under conditions of high shear stress.

catalyze the transfer of the gamma-phosphoryl group from
ATP to serine/threonine residues on protein substrates.
The MAST kinase 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 MAST kinase subfamily
includes MAST kinases, MAST-like (MASTL) kinases, and
fungal kinases with similarity to Saccharomyces
cerevisiae Rim15 and Schizosaccharomyces pombe cek1.
MAST kinases contain an N-terminal domain of unknown
function, a central catalytic domain, and a C-terminal
PDZ domain that mediates protein-protein interactions.
MASTL kinases carry only a catalytic domain which
contains a long insert relative to other kinases. The
fungal kinases in this subfamily harbor other domains in
addition to a central catalytic domain, which also
contains an insert relative to MAST kinases like MASTL.
Rim15 contains a C-terminal signal receiver (REC) domain
while cek1 contains an N-terminal PAS domain. MAST
kinases are cytoskeletal associated kinases of unknown
function that are also expressed at neuromuscular
junctions and postsynaptic densities. The fungal
proteins Rim15 and cek1 are involved in the regulation
of meiosis and mitosis, respectively.

>gnl|CDD|188944 cd09545, SAM_EPH-A4, SAM domain of EPH-A4 subfamily of tyrosine
kinase receptors. SAM (sterile alpha motif) domain of
EPH-A4 subfamily of receptor tyrosine kinases is a
C-terminal potential protein-protein interaction domain.
This domain is located in the cytoplasmic region of
EPH-A4 receptors and appears to mediate cell-cell
initiated signal transduction. SAM domains of EPH-A4
receptors can form homodimers. EPH-A4 receptors bind
ligands such as erphirin A1, A4, A5. They are known to
interact with a number of different proteins, including
meltrin beta metalloprotease, Cdk5, and EFS2alpha,
however SAM domain doesn't participate in these
interactions. EPH-A4 receptors are involved in
regulation of corticospinal tract formation, in pathway
controlling voluntary movements, in formation of motor
neurons, and in axon guidance (SAM domain is not
required for axon guidance or for EPH-A4 kinase
signaling). In Xenopus embryos EPH-A4 induces loss of
cell adhesion, ventro-lateral protrusions, and severely
expanded posterior structures. Mutations in SAM domain
conserved tyrosine (Y928F) enhance the ability of EPH-A4
to induce these phenotypes, thus supporting the idea
that the SAM domain may negatively regulate some aspects
of EPH-A4 activity. EphA4 gene was found overexpressed
in a number of different cancers including human gastric
cancer, colorectal cancer, and pancreatic ductal
adenocarcinoma. It is likely to be a promising molecular
target for the cancer therapy.

discovered in a screen for antiapoptotic genes. It
phosphorylates and inhibits the proapoptotic proteins,
Bad and FKHRL1. SGK3 also regulates many transporters,
ion channels, and receptors. It plays a critical role in
hair follicle morphogenesis and hair cycling.

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. MAP4K3 plays a role in the
nutrient-responsive pathway of mTOR (mammalian target of
rapamycin) signaling. MAP4K3 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. mTOR regulates ribosome
biogenesis and protein translation, and is frequently
deregulated in cancer.

TAO3 is also known as JIK (JNK inhibitory kinase) or KFC
(kinase from chicken). It specifically activates c-Jun
N-terminal kinase (JNK), presumably by phosphorylating
and activating MKK4/MKK7. In Saccharomyces cerevisiae,
TAO3 is a component of the RAM (regulation of Ace2p
activity and cellular morphogenesis) signaling pathway.
TAO3 is upregulated in retinal ganglion cells after
axotomy, and may play a role in apoptosis.

TAO1 is sometimes referred to as prostate-derived
sterile 20-like kinase 2 (PSK2). TAO1 activates the p38
MAPK through direct interaction with and activation of
MEK3. TAO1 is highly expressed in the brain and may play
a role in neuronal apoptosis. TAO1 interacts with the
checkpoint proteins BubR1 and Mad2, and plays an
important role in regulating mitotic progression, which
is required for both chromosome congression and
checkpoint-induced anaphase delay. TAO1 may play a role
in protecting genomic stability.
