>gnl|CDD|176563 cd08626, PI-PLCc_beta4, Catalytic domain of metazoan
phosphoinositide-specific phospholipase C-beta4. This
subfamily corresponds to the catalytic domain present in
metazoan phosphoinositide-specific phospholipase C
(PI-PLC, EC 3.1.4.11)-beta isozyme 4. PI-PLC is a
signaling enzyme that hydrolyzes the membrane
phospholipids phosphatidylinositol-4,5-bisphosphate
(PIP2) to generate two important second messengers in
eukaryotic signal transduction cascades, Inositol
1,4,5-trisphosphate (InsP3) and diacylglycerol (DAG).
InsP3 triggers inflow of calcium from intracellular
stores, while DAG, together with calcium, activates
protein kinase C, which goes on to phosphorylate other
molecules, leading to altered cellular activity. Calcium
is required for the catalysis. PLC-beta represents a
class of mammalian PI-PLC that has an N-terminal
pleckstrin homology (PH) domain, an array of EF hands, a
PLC catalytic core domain, a C2 domain, and a unique
C-terminal coiled-coil (CT) domain necessary for
homodimerization. The PLC catalytic core domain is a TIM
barrel with two highly conserved regions (X and Y) split
by a highly degenerate linker sequence. PI-PLC-beta4 is
expressed in high concentrations in cerebellar Purkinje
and granule cells, the median geniculate body, and the
lateral geniculate nucleus. It is activated by the
heterotrimeric G protein alpha q subunits through their
C2 domain and long C-terminal extension.

this subfamily, such as NorpA and PLC-21 from Drosophila
and PLC-beta from turkey, Xenopus, sponge, and hydra.

subfamily corresponds to the catalytic domain present in
metazoan phosphoinositide-specific phospholipase C
(PI-PLC, EC 3.1.4.11)-delta isozymes. PI-PLC is a

This CD corresponds to the catalytic domain which is a
TIM barrel with two highly conserved regions (X and Y)
split by a highly degenerate linker sequence. There are
three PI-PLC-delta isozymes (1,3 and 4). PI-PLC-delta1
is relatively well characterized. It is activated by
high calcium levels generated by other PI-PLC family
members, and therefore functions as a calcium amplifier
within the cell. Different PI-PLC-delta isozymes have
different tissue distribution and different subcellular
locations. PI-PLC-delta1 is mostly a cytoplasmic
protein, PI-PLC-delta3 is located in the membrane, and
PI-PLC-delta4 is predominantly detected in the cell
nucleus. Aside from three PI-PLC-delta isozymes
identified in mammals, some eukaryotic PI-PLC-delta
homologs have been classified to this CD.

>gnl|CDD|176501 cd08558, PI-PLCc_eukaryota, Catalytic domain of eukaryotic
phosphoinositide-specific phospholipase C and similar
proteins. This family corresponds to the catalytic
domain present in eukaryotic phosphoinositide-specific
phospholipase C (PI-PLC, EC 3.1.4.11) and similar
proteins. The higher eukaryotic PI-PLCs play a critical
role in most signal transduction pathways, controlling
numerous cellular events such as cell growth,
proliferation, excitation and secretion. They strictly
require Ca2+ for the catalytic activity. They display a
clear preference towards the hydrolysis of the more
highly phosphorylated membrane phospholipids
PI-analogues, phosphatidylinositol 4,5-bisphosphate
(PIP2) and phosphatidylinositol-4-phosphate (PIP), to
generate two important second messengers in eukaryotic
signal transduction cascades, inositol
1,4,5-trisphosphate (InsP3) and diacylglycerol (DAG).
InsP3 triggers inflow of calcium from intracellular
stores, while DAG, together with calcium, activates
protein kinase C, which then phosphorylates other
molecules, leading to altered cellular activity. The
eukaryotic PI-PLCs have a multidomain organization that
consists of a PLC catalytic core domain, and various
regulatory domains, such as the pleckstrin homology (PH)
domain, EF-hand motif, and C2 domain. The catalytic core
domain is a TIM barrel with two highly conserved regions
(X and Y) split by a linker region. The catalytic
mechanism of eukaryotic PI-PLCs is based on general base
and acid catalysis utilizing two well conserved
histidines and consists of two steps, a phosphotransfer
and a phosphodiesterase reaction. The mammalian PI-PLCs
consist of 13 isozymes, which are classified into
six-subfamilies, PI-PLC-delta (1,3 and 4), -beta(1-4),
-gamma(1,2), -epsilon, -zeta, and -eta (1,2). Ca2+ is
required for the activation of all forms of mammalian
PI-PLCs, and the concentration of calcium influences
substrate specificity. This family also includes
metazoan phospholipase C related but catalytically
inactive proteins (PRIP), which belong to a group of
novel inositol trisphosphate binding proteins. Due to
the replacement of critical catalytic residues, PRIP
does not have PLC enzymatic activity.

>gnl|CDD|176560 cd08623, PI-PLCc_beta1, Catalytic domain of metazoan
phosphoinositide-specific phospholipase C-beta1. This
subfamily corresponds to the catalytic domain present in
metazoan phosphoinositide-specific phospholipase C
(PI-PLC, EC 3.1.4.11)-beta isozyme 1. PI-PLC is a
signaling enzyme that hydrolyzes the membrane
phospholipids phosphatidylinositol-4,5-bisphosphate
(PIP2) to generate two important second messengers in
eukaryotic signal transduction cascades, Inositol
1,4,5-trisphosphate (InsP3) and diacylglycerol (DAG).
InsP3 triggers inflow of calcium from intracellular
stores, while DAG, together with calcium, activates
protein kinase C, which goes on to phosphorylate other
molecules, leading to altered cellular activity. Calcium
is required for the catalysis. PLC-beta represents a
class of mammalian PI-PLC that has an N-terminal
pleckstrin homology (PH) domain, an array of EF hands, a
PLC catalytic core domain, a C2 domain, and a unique
C-terminal coiled-coil (CT) domain necessary for
homodimerization. The PLC catalytic core domain is a TIM
barrel with two highly conserved regions (X and Y) split
by a highly degenerate linker sequence. PI-PLC-beta1 is
expressed at highest levels in specific regions of the
brain. It is activated by the heterotrimeric G protein
alpha q subunits through their C2 domain and long
C-terminal extension.

eukaryotic PI-PLC-gamma homologs have been classified
with this subfamily.

>gnl|CDD|176540 cd08598, PI-PLC1c_yeast, Catalytic domain of putative yeast
phosphatidylinositide-specific phospholipases C. This
family corresponds to the catalytic domain present in a
group of putative phosphoinositide-specific
phospholipase C (PI-PLC, EC 3.1.4.11) encoded by PLC1
genes from yeasts, which are homologs of the delta
isoforms of mammalian PI-PLC in terms of overall
sequence similarity and domain organization. Mammalian
PI-PLC is a signaling enzyme that hydrolyzes the
membrane phospholipids
phosphatidylinositol-4,5-bisphosphate (PIP2) to
generate two important second messengers in eukaryotic
signal transduction cascades, inositol
1,4,5-trisphosphate (InsP3) and diacylglycerol (DAG).
InsP3 triggers inflow of calcium from intracellular
stores, while DAG, together with calcium, activates
protein kinase C, which then phosphorylates other
molecules, leading to altered cellular activity. Calcium
is required for the catalysis. The prototype of this CD
is protein Plc1p encoded by PLC1 genes from
Saccharomyces cerevisiae. Plc1p contains both highly
conserved X- and Y- regions of PLC catalytic core
domain, as well as a presumptive EF-hand like calcium
binding motif. Experiments show that Plc1p displays
calcium dependent catalytic properties with high
similarity to those of the mammalian PLCs, and plays
multiple roles in modulating the membrane/protein
interactions in filamentation control. CaPlc1p encoded
by CAPLC1 from the closely related yeast Candida
albicans, an orthologue of S. cerevisiae Plc1p, is also
included in this group. Like Plc1p, CaPlc1p has
conserved presumptive catalytic domain, shows PLC
activity when expressed in E. coli, and is involved in
multiple cellular processes. There are two other gene
copies of CAPLC1 in C. albicans, CAPLC2 (also named as
PIPLC) and CAPLC3. Experiments show CaPlc1p is the only
enzyme in C. albicans which functions as PLC. The
biological functions of CAPLC2 and CAPLC3 gene products
must be clearly different from CaPlc1p, but their exact
roles remain unclear. Moreover, CAPLC2 and CAPLC3 gene
products are more similar to extracellular bacterial
PI-PLC than to the eukaryotic PI-PLC, and they are not
included in this subfamily.

phospholipase C related, but catalytically inactive
protein. This family corresponds to the catalytic
domain present in metazoan phospholipase C related, but
catalytically inactive proteins (PRIP), which belong to
a group of novel Inositol 1,4,5-trisphosphate (InsP3)
binding protein. PRIP has a primary structure and domain
architecture, incorporating a pleckstrin homology (PH)
domain, an array of EF hands, a PLC catalytic core
domain with highly conserved X- and Y-regions split by a
linker sequence, and a C-terminal C2 domain, similar to
phosphoinositide-specific phospholipases C (PI-PLC, EC
3.1.4.11)-delta isoforms. Due to replacement of critical
catalytic residues, PRIP do not have PLC enzymatic
activity. PRIP consists of two subfamilies,
PRIP-1(previously known as p130 or PLC-1), which is
predominantly expressed in the brain, and PRIP-2
(previously known as PLC-2), which exhibits a relatively
ubiquitous expression. Experiments show both, PRIP-1 and
PRIP-2, are involved in InsP3-mediated calcium signaling
pathway and GABA(A)receptor-mediated signaling pathway.
In addition, PRIP-2 acts as a negative regulator of
B-cell receptor signaling and immune responses.

phospholipids phosphatidylinositol-4,5-bisphosphate
(PIP2) to generate two important second messengers in
eukaryotic signal transduction cascades, Inositol
1,4,5-trisphosphate (InsP3) and diacylglycerol (DAG).
InsP3 triggers inflow of calcium from intracellular
stores, while DAG, together with calcium, activates
protein kinase C, which then phosphorylates other
molecules, leading to altered cellular activity. Calcium
is required for the catalysis. PI-PLC-eta represents a
class of neuron-speific PI-PLC that has an N-terminal
pleckstrin homology (PH) domain, an array of EF hands, a
PLC catalytic core domain, a C2 domain, and a unique
C-terminal tail that terminates with a PDZ-binding
motif, a potential interaction site for other signaling
proteins. The PLC catalytic core domain is a TIM barrel
with two highly conserved regions (X and Y) split by a
highly degenerate linker sequence. There are two
PI-PLC-eta isozymes (1-2), both neuron-specific enzymes.
They function as calcium sensors that are activated by
small increases in intracellular calcium concentrations.
The PI-PLC-eta isozymes are also activated through GPCR
stimulation. Aside from the PI-PLC-eta isozymes
identified in mammals, their eukaryotic homologs are
also present in this family.

phospholipids phosphatidylinositol-4,5-bisphosphate
(PIP2) to generate two important second messengers in

InsP3 triggers inflow of calcium from intracellular

protein kinase C, which goes on to phosphorylate other
molecules, leading to altered cellular activity. Calcium
is required for the catalysis. PI-PLC-gamma represents a
class of mammalian PI-PLC that has an N-terminal
pleckstrin homology (PH) domain, an array of EF hands, a
PLC catalytic core domain, and a C2 domain. The PLC
catalytic core domain is a TIM barrel with two highly
conserved regions (X and Y) split by a highly degenerate
linker sequence. Unique to PI-PLC-gamma2, a second PH
domain, two SH2 (Src homology 2) regions, and one SH3
(Src homology 3) region is present within this linker
region. PI-PLC-gamma2 is highly expressed in cells of
hematopoietic origin. It is activated by receptor and
non-receptor tyrosine kinases due to the presence of two
SH2 and a single SH3 domain within the linker region.
Unlike PI-PLC-gamma1, the activation of PI-PLC-gamma2
may require concurrent stimulation of PI 3-kinase.

>gnl|CDD|241515 cd13361, PH_PLC_beta, Phospholipase C-beta (PLC-beta) pleckstrin
homology (PH) domain. PLC-beta (PLCbeta) is regulated
by heterotrimeric G protein-coupled receptors through
their C2 domain and long C-terminal extension which
forms an autoinhibitory helix. There are four isoforms:
PLC-beta1-4. The PH domain of PLC-beta2 and PLC-beta3
plays a dual role, much like PLC-delta1, by binding to
the plasma membrane, as well as the interaction site for
the catalytic activator. However, PLC-beta binds to the
lipid surface independent of PIP2. PLC-beta1 seems to
play unspecified roles in cellular proliferation and
differentiation. PLC-beta consists of an N-terminal PH
domain, a EF hand domain, a catalytic domain split into
X and Y halves, a C2 domain and a C-terminal PDZ.
Members of the Rho GTPase family (e.g., Rac1, Rac2,
Rac3, and cdc42) have been implicated in their
activation by binding to an alternate site on the
N-terminal PH domain. A basic amino acid region within
the enzyme's long C-terminal tail appears to function as
a Nuclear Localization Signal for import into the
nucleus. PLCs (EC 3.1.4.3) play a role in the initiation
of cellular activation, proliferation, differentiation
and apoptosis. They are central to inositol lipid
signalling pathways, facilitating intracellular Ca2+
release and protein kinase C (PKC) activation.
Specificaly, PLCs catalyze the cleavage of
phosphatidylinositol-4,5-bisphosphate (PIP2) and result
in the release of 1,2-diacylglycerol (DAG) and inositol
1,4,5-triphosphate (IP3). These products trigger the
activation of protein kinase C (PKC) and the release of
Ca2+ from intracellular stores. There are fourteen kinds
of mammalian phospholipase C proteins which are are
classified into six isotypes (beta, gamma, delta,
epsilon, zeta, eta). PH domains have diverse functions,
but in general are involved in targeting proteins to the
appropriate cellular location or in the interaction with
a binding partner. They share little sequence
conservation, but all have a common fold, which is
electrostatically polarized. Less than 10% of PH domains
bind phosphoinositide phosphates (PIPs) with high
affinity and specificity. PH domains are distinguished
from other PIP-binding domains by their specific
high-affinity binding to PIPs with two vicinal phosphate
groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3
which results in targeting some PH domain proteins to
the plasma membrane. A few display strong specificity in
lipid binding. Any specificity is usually determined by
loop regions or insertions in the N-terminus of the
domain, which are not conserved across all PH domains.
PH domains are found in cellular signaling proteins such
as serine/threonine kinase, tyrosine kinases, regulators
of G-proteins, endocytotic GTPases, adaptors, as well as
cytoskeletal associated molecules and in lipid
associated enzymes.the plasma membrane, but only a few
(less than 10%) display strong specificity in binding
inositol phosphates. Any specificity is usually
determined by loop regions or insertions in the
N-terminus of the domain, which are not conserved across
all PH domains. PH domains are found in cellular
signaling proteins such as serine/threonine kinases,
tyrosine kinases, regulators of G-proteins, endocytotic
GTPases, adaptors, cytoskeletal associated molecules,
and in lipid associated enzymes.

excitation and secretion. These PI-PLCs strictly require
Ca2+ for their catalytic activity. They display a clear
preference towards the hydrolysis of the more highly
phosphorylated PI-analogues, PIP2 and PIP, to generate
two important second messengers, InsP3 and DAG. InsP3
triggers inflow of calcium from intracellular stores,
while DAG, together with calcium, activates protein
kinase C, which then phosphorylates other molecules,
leading to altered cellular activity. In contrast,
bacterial PI-PLCs contain a single catalytic domain.
Although their precise physiological function remains
unclear, bacterial PI-PLCs may function as virulence
factors in some pathogenic bacteria. They participate in
Ca2+-independent PI metabolism. They are characterized
as phosphatidylinositol-specific phospholipase C (EC
4.6.1.13) that selectively hydrolyze PI, not PIP or
PIP2. The TIM-barrel type catalytic domain in bacterial
PI-PLCs is very similar to the one in eukaryotic
PI-PLCs, in which the catalytic domain is assembled from
two highly conserved X- and Y-regions split by a
divergent linker sequence. The catalytic mechanism of
both prokaryotic and eukaryotic PI-PLCs is based on
general base and acid catalysis utilizing two well
conserved histidines, and consists of two steps, a
phosphotransfer and a phosphodiesterase reaction. This
superfamily also includes a distinctly different type of
eukaryotic PLC, glycosylphosphatidylinositol-specific
phospholipase C (GPI-PLC), an integral membrane protein
characterized in the protozoan parasite Trypanosoma
brucei. T. brucei GPI-PLC hydrolyzes the GPI-anchor on
the variant specific glycoprotein (VSG), releasing
dimyristyl glycerol (DMG), which may facilitate the
evasion of the protozoan to the host#s immune system. It
does not require Ca2+ for its activity and is more
closely related to bacterial PI-PLCs, but not mammalian
PI-PLCs.

>gnl|CDD|176541 cd08599, PI-PLCc_plant, Catalytic domain of plant
phosphatidylinositide-specific phospholipases C. This
family corresponds to the catalytic domain present in a
group of phosphoinositide-specific phospholipases C
(PI-PLC, EC 3.1.4.11) encoded by PLC genes from higher
plants, which are homologs of mammalian PI-PLC in terms
of overall sequence similarity and domain organization.
Mammalian PI-PLC is a signaling enzyme that hydrolyzes
the membrane phospholipids
phosphatidylinositol-4,5-bisphosphate (PIP2) to
generate two important second messengers in eukaryotic
signal transduction cascades, inositol
1,4,5-trisphosphate (InsP3) and diacylglycerol (DAG).
InsP3 triggers inflow of calcium from intracellular
stores, while DAG, together with calcium, activates
protein kinase C, which then phosphorylates other
molecules, leading to altered cellular activity. Calcium
is required for the catalysis. The domain arrangement of
plant PI-PLCs is structurally similar to the mammalian
PLC-zeta isoform, which lacks the N-terminal pleckstrin
homology (PH) domain, but contains EF-hand like motifs
(which are absent in a few plant PLCs), a PLC catalytic
core domain with X- and Y- highly conserved regions
split by a linker sequence, and a C2 domain. However, at
the sequence level, the plant PI-PLCs are closely
related to the mammalian PLC-delta isoform. Experiments
show that plant PLCs display calcium dependent PLC
catalytic properties, although they lack some of the
N-terminal motifs found in their mammalian counterparts.
A putative calcium binding site may be located at the
region spanning the X- and Y- domains.

>gnl|CDD|176498 cd08555, PI-PLCc_GDPD_SF, Catalytic domain of
phosphoinositide-specific phospholipase C-like
phosphodiesterases superfamily. The PI-PLC-like
phosphodiesterases superfamily represents the catalytic
domains of bacterial phosphatidylinositol-specific
phospholipase C (PI-PLC, EC 4.6.1.13), eukaryotic
phosphoinositide-specific phospholipase C (PI-PLC, EC
3.1.4.11), glycerophosphodiester phosphodiesterases
(GP-GDE, EC 3.1.4.46), sphingomyelinases D (SMases D)
(sphingomyelin phosphodiesterase D, EC 3.1.4.41) from
spider venom, SMases D-like proteins, and phospholipase
D (PLD) from several pathogenic bacteria, as well as
their uncharacterized homologs found in organisms
ranging from bacteria and archaea to metazoans, plants,
and fungi. PI-PLCs are ubiquitous enzymes hydrolyzing
the membrane lipid phosphoinositides to yield two
important second messengers, inositol phosphates and
diacylglycerol (DAG). GP-GDEs play essential roles in
glycerol metabolism and catalyze the hydrolysis of
glycerophosphodiesters to sn-glycerol-3-phosphate (G3P)
and the corresponding alcohols that are major sources of
carbon and phosphate. Both, PI-PLCs and GP-GDEs, can
hydrolyze the 3'-5' phosphodiester bonds in different
substrates, and utilize a similar mechanism of general
base and acid catalysis with conserved histidine
residues, which consists of two steps, a phosphotransfer
and a phosphodiesterase reaction. This superfamily also
includes Neurospora crassa ankyrin repeat protein NUC-2
and its Saccharomyces cerevisiae counterpart, Phosphate
system positive regulatory protein PHO81,
glycerophosphodiester phosphodiesterase (GP-GDE)-like
protein SHV3 and SHV3-like proteins (SVLs). The residues
essential for enzyme activities and metal binding are
not conserved in these sequence homologs, which might
suggest that the function of catalytic domains in these
proteins might be distinct from those in typical
PLC-like phosphodiesterases.

motility protein 1 pleckstrin homology domain. The
C-terminal region of ELMO1, the PH domain and Pro-rich
sequences, binds the SH3-containing region of DOCK2
forming a intermolecular five-helix bundle allowing for
DOCK mediated Rac1 activation. ELMO1, a mammalian
homolog of C. elegans CED-12, contains an N-terminal
RhoG-binding region, a ELMO domain, a PH domain, and a
C-terminal sequence with three PxxP motifs.
Specificaly, PLCs catalyze the cleavage of
phosphatidylinositol-4,5-bisphosphate (PIP2) and result
in the release of 1,2-diacylglycerol (DAG) and inositol
1,4,5-triphosphate (IP3). These products trigger the
activation of protein kinase C (PKC) and the release of
Ca2+ from intracellular stores. There are fourteen
kinds of mammalian phospholipase C which are are
classified into six isotypes (beta, gamma, delta,
epsilon, zeta, eta). All PLCs, except for PLCzeta, have
a PH domain which is for most part N-terminally
located, though lipid binding specificity is not
conserved between them. In addition PLC gamma contains
a split PH domain within its catalytic domain that is
separated by 2 SH2 domains and a single SH3 domain. PH
domains have diverse functions, but in general are
involved in targeting proteins to the appropriate
cellular location or in the interaction with a binding
partner. They share little sequence conservation, but
all have a common fold, which is electrostatically
polarized. Less than 10% of PH domains bind
phosphoinositide phosphates (PIPs) with high affinity
and specificity. PH domains are distinguished from
other PIP-binding domains by their specific
high-affinity binding to PIPs with two vicinal
phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or
PtdIns(3,4,5)P3 which results in targeting some PH
domain proteins to the plasma membrane. A few display
strong specificity in lipid binding. Any specificity is
usually determined by loop regions or insertions in the
N-terminus of the domain, which are not conserved
across all PH domains. PH domains are found in cellular
signaling proteins such as serine/threonine kinase,
tyrosine kinases, regulators of G-proteins, endocytotic
GTPases, adaptors, as well as cytoskeletal associated
molecules and in lipid associated enzymes.
