>gnl|CDD|119427 cd05167, PI4Kc_III_alpha, Phosphoinositide 4-kinase (PI4K), Type
III, alpha 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. 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.

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.

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.

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 II PI3Ks preferentially use
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
homology (PX) domain, and a second C2 domain at the
C-terminus. They are activated by a variety of stimuli
including chemokines, cytokines, lysophosphatidic acid
(LPA), insulin, and tyrosine kinase receptors.

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. PI3Kdelta is mainly
expressed in immune cells and plays an important role in
cellular and humoral immunity. It plays a major role in
antigen receptor signaling in B-cells, T-cells, and mast
cells. It regulates the differentiation of peripheral
helper T-cells and controls the development and function
of regulatory T-cells.

Dehydroquinate synthase (DHQS) catalyzes the conversion
of 3-deoxy-D-arabino-heptulosonate-7-phosphate (DAHP) to
dehydroquinate (DHQ) in the second step of the shikimate
pathway. This pathway involves seven sequential
enzymatic steps in the conversion of erythrose
4-phosphate and phosphoenolpyruvate into chorismate for
subsequent synthesis of aromatic compounds.
Dehydroquinate synthase-like group includes
dehydroquinate synthase, 2-deoxy-scyllo-inosose
synthase, and 2-epi-5-epi-valiolone synthase. The
alcohol dehydrogenases in this superfamily contain a
dehydroquinate synthase-like protein structural fold and
mostly contain iron. They are distinct from other
alcohol dehydrogenases which contains different protein
domains. There are several distinct families of alcohol
dehydrogenases: Zinc-containing long-chain alcohol
dehydrogenases; insect-type, or short-chain alcohol
dehydrogenases; iron-containing alcohol dehydrogenases,
and others. The iron-containing family has a Rossmann
fold-like topology that resembles the fold of the
zinc-dependent alcohol dehydrogenases, but lacks
sequence homology, and differs in strand arrangement.
ADH catalyzes the reversible oxidation of alcohol to
acetaldehyde with the simultaneous reduction of NAD(P)+
to NAD(P)H.

the catalytic domains of other protein STKs, protein
tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase (PI3K). This subfamily is composed of the
cAMP-dependent proteins kinases, PKA and PRKX. The
inactive PKA holoenzyme is a heterotetramer composed of
two phosphorylated and active catalytic (C) subunits
with a dimer of regulatory (R) subunits. Activation is
achieved through the binding of the important second
messenger cAMP to the R subunits, which leads to the
dissociation of PKA into the R dimer and two active C
subunits. PKA is present ubiquitously in cells and
interacts with many different downstream targets. It
plays a role in the regulation of diverse processes such
as growth, development, memory, metabolism, gene
expression, immunity, and lipolysis.

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.

signaling pathways are important mediators of cellular

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

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

is crucial in oncogenesis, cancer chemoresistance, and

inhibition by Gadd45beta and the subsequent suppression
of the JNK cascade.
