>gnl|CDD|197327 cd09093, INPP5c_INPP5B, Catalytic inositol polyphosphate
5-phosphatase (INPP5c) domain of Type II inositol
polyphosphate 5-phosphatase I, Oculocerebrorenal
syndrome of Lowe 1, and related proteins. This
subfamily contains the INPP5c domain of type II inositol
polyphosphate 5-phosphatase I (INPP5B),
Oculocerebrorenal syndrome of Lowe 1 (OCRL-1), and
related proteins. It belongs to a family of
Mg2+-dependent inositol polyphosphate 5-phosphatases,
which hydrolyze the 5-phosphate from the inositol ring
of various 5-position phosphorylated phosphoinositides
(PIs) and inositol phosphates (IPs), and to the large
EEP (exonuclease/endonuclease/phosphatase) superfamily
that contains functionally diverse enzymes that share a
common catalytic mechanism of cleaving phosphodiester
bonds. INPP5B and OCRL1 preferentially hydrolyze the
5-phosphate of phosphatidylinositol (4,5)- bisphosphate
[PI(4,5)P2] and phosphatidylinositol (3,4,5)-
trisphosphate [PI(3,4,5)P3]. INPP5B can also hydrolyze
soluble inositol (1,4,5)-trisphosphate [I(1,4,5)P3] and
inositol (1,3,4,5)-tetrakisphosphate [I(1,3,4,5)P4].
INPP5B participates in the endocytic pathway and in the
early secretory pathway. In the latter, it may function
in retrograde ERGIC (ER-to-Golgi intermediate
compartment)-to-ER transport; it binds specific RAB
proteins within the secretory pathway. In the endocytic
pathway, it binds RAB5 and during endocytosis, may
function in a RAB5-controlled cascade for converting
PI(3,4,5)P3 to phosphatidylinositol 3-phosphate (PI3P).
This cascade may link growth factor signaling and
membrane dynamics. Mutation in OCRL1 is implicated in
Lowe syndrome, an X-linked recessive multisystem
disorder, which includes defects in eye, brain, and
kidney function, and in Type 2 Dent's disease, a
disorder with only the renal symptoms. OCRL-1 may have a
role in membrane trafficking within the endocytic
pathway and at the trans-Golgi network, and may
participate in actin dynamics or signaling from
endomembranes. OCRL1 and INPP5B have overlapping
functions: deletion of both 5-phosphatases in mice is
embryonic lethal, deletion of OCRL1 alone has no
phenotype, and deletion of Inpp5b alone has only a mild
phenotype (male sterility). Several of the proteins that
interact with OCRL1 also bind INPP5B, for examples,
inositol polyphosphate phosphatase interacting protein
of 27kDa (IPIP27)A and B (also known as Ses1 and 2), and
endocytic signaling adaptor APPL1. OCRL1, but not
INPP5B, binds clathrin heavy chain, the plasma membrane
AP2 adaptor subunit alpha-adaptin. In addition to this
INPP5c domain, most proteins in this subfamily have a
C-terminal RhoGAP (GTPase-activator protein [GAP] for
Rho-like small GTPases) domain.

5-phosphatase J and related proteins. INPP5c domain of
Inositol polyphosphate-5-phosphatase J (INPP5J), also
known as PIB5PA or PIPP, and related proteins. This
subfamily belongs to a family of Mg2+-dependent inositol

common catalytic mechanism of cleaving phosphodiester
bonds. INPP5J hydrolyzes PI(4,5)P2, I(1,4,5)P3, and
I(1,3,4,5)P4 at ruffling membranes. These proteins
contain a C-terminal, SKIP carboxyl homology domain
(SKICH), which may direct plasma membrane ruffle
localization.

>gnl|CDD|197323 cd09089, INPP5c_Synj, Catalytic inositol polyphosphate
5-phosphatase (INPP5c) domain of synaptojanins. This
subfamily contains the INPP5c domains of two human
synaptojanins, synaptojanin 1 (Synj1) and synaptojanin 2
(Synj2), and related proteins. It belongs to a family of
Mg2+-dependent inositol polyphosphate 5-phosphatases,
which hydrolyze the 5-phosphate from the inositol ring
of various 5-position phosphorylated phosphoinositides
(PIs) and inositol phosphates (IPs). They belong to the
large EEP (exonuclease/endonuclease/phosphatase)
superfamily that contains functionally diverse enzymes
that share a common catalytic mechanism of cleaving
phosphodiester bonds. Synj1 occurs as two main isoforms:
a brain enriched 145 KDa protein (Synj1-145) and a
ubiquitously expressed 170KDa protein (Synj1-170).
Synj1-145 participates in clathrin-mediated endocytosis.
The primary substrate of the Synj1-145 INPP5c domain is
PI(4,5)P2, which it converts to PI4P. Synj1-145 may work
with membrane curvature sensors/generators (such as
endophilin) to remove PI(4,5)P2 from curved membranes.
The recruitment of the INPP5c domain of Synj1-145 to
endophilin-induced membranes leads to a fragmentation
and condensation of these structures. The PI(4,5)P2 to
PI4P conversion may cooperate with dynamin to produce
membrane fission. In addition to this INPP5c domain,
Synjs contain an N-terminal Sac1-like domain; the Sac1
domain can dephosphorylate a variety of
phosphoinositides in vitro. Synj2 can hydrolyze
phosphatidylinositol diphosphate (PIP2) to
phosphatidylinositol phosphate (PIP). Synj2 occurs as
multiple alternative splice variants in various tissues.
These variants share the INPP5c domain and the Sac1
domain. Synj2A is recruited to the mitochondria via its
interaction with OMP25 (a mitochondrial outer membrane
protein). Synj2B is found at nerve terminals in the
brain and at the spermatid manchette in testis. Synj2B
undergoes further alternative splicing to give 2B1 and
2B2. In clathrin-mediated endocytosis, Synj2
participates in the formation of clathrin-coated pits,
and perhaps also in vesicle decoating. Rac1 GTPase
regulates the intracellular localization of Synj2 forms,
but not Synj1. Synj2 may contribute to the role of Rac1
in cell migration and invasion, and is a potential
target for therapeutic intervention in malignant tumors.

>gnl|CDD|197308 cd09074, INPP5c, Catalytic domain of inositol polyphosphate
5-phosphatases. Inositol polyphosphate 5-phosphatases
(5-phosphatases) are signal-modifying enzymes, which
hydrolyze the 5-phosphate from the inositol ring of
specific 5-position phosphorylated phosphoinositides
(PIs) and inositol phosphates (IPs), such as PI(4,5)P2,
PI(3,4,5)P3, PI(3,5)P2, I(1,4,5)P3, and I(1,3,4,5)P4.
These enzymes are Mg2+-dependent, and belong to the
large EEP (exonuclease/endonuclease/phosphatase)
superfamily that contains functionally diverse enzymes
that share a common catalytic mechanism of cleaving
phosphodiester bonds. In addition to this INPP5c domain,
5-phosphatases often contain additional domains and
motifs, such as the SH2 domain, the Sac-1 domain, the
proline-rich domain (PRD), CAAX, RhoGAP
(RhoGTPase-activating protein), and SKICH [SKIP
(skeletal muscle- and kidney-enriched inositol
phosphatase) carboxyl homology] domains, that are
important for protein-protein interactions and/or for
the subcellular localization of these enzymes.
5-phosphatases incorporate into large signaling
complexes, and regulate diverse cellular processes
including postsynaptic vesicular trafficking, insulin
signaling, cell growth and survival, and endocytosis.
Loss or gain of function of 5-phosphatases is implicated
in certain human diseases. This family also contains a
functionally unrelated nitric oxide transport protein,
Cimex lectularius (bedbug) nitrophorin, which catalyzes
a heme-assisted S-nitrosation of a proximal thiolate;
the heme however binds at a site distinct from the
active site of the 5-phosphatases.

5-phosphatase (INPP5c) domain of Saccharomyces
cerevisiae Inp51p, Inp52p, and Inp53p, and related
proteins. This subfamily contains the INPP5c domain of
three Saccharomyces cerevisiae synaptojanin-like
inositol polyphosphate 5-phosphatases (INP51, INP52, and
INP53), Schizosaccharomyces pombe synaptojanin
(SPsynaptojanin), and related proteins. It belongs to a
family of Mg2+-dependent inositol polyphosphate
5-phosphatases, which hydrolyze the 5-phosphate from the
inositol ring of various 5-position phosphorylated
phosphoinositides (PIs) and inositol phosphates (IPs),
and to the large EEP
(exonuclease/endonuclease/phosphatase) superfamily that
contains functionally diverse enzymes that share a
common catalytic mechanism of cleaving phosphodiester
bonds. In addition to this INPP5c domain, these proteins
have an N-terminal catalytic Sac1-like domain (found in
other proteins including the phophoinositide phosphatase
Sac1p), and a C-terminal proline-rich domain (PRD). The
Sac1 domain allows Inp52p and Inp53p to recognize and
dephosphorylate a wider range of substrates including
PI3P, PI4P, and PI(3,5)P2. The Sac1 domain of Inp51p is
non-functional. Disruption of any two of INP51, INP52,
and INP53, in S. cerevisiae leads to abnormal vacuolar
and plasma membrane morphology. During hyperosmotic
stress, Inp52p and Inp53p localize at actin patches,
where they may facilitate the hydrolysis of PI(4,5)P2,
and consequently promote actin rearrangement to regulate
cell growth. SPsynaptojanin is also active against a
range of soluble and lipid inositol phosphates,
including I(1,4,5)P3, I(1,3,4,5)P4, I(1,4,5,6)P4,
PI(4,5)P2, and PIP3. Transformation of S. cerevisiae
with a plasmid expressing the SPsynaptojanin
5-phosphatase domain rescues inp51/inp52/inp53
triple-mutant strains.

5-phosphatase (INPP5c) domain of Inositol
polyphosphate-5-phosphatase E and related proteins.
INPP5c domain of Inositol polyphosphate-5-phosphatase E
(also called type IV or 72 kDa 5-phosphatase), rat
pharbin, and related proteins. This subfamily belongs to
a family of Mg2+-dependent inositol polyphosphate
5-phosphatases, which hydrolyze the 5-phosphate from the
inositol ring of various 5-position phosphorylated
phosphoinositides (PIs) and inositol phosphates (IPs),
and to the large EEP
(exonuclease/endonuclease/phosphatase) superfamily that
contains functionally diverse enzymes that share a
common catalytic mechanism of cleaving phosphodiester
bonds. INPP5E hydrolyzes the 5-phosphate from PI(3,5)P2,
PI(4,5)P2 and PI(3,4,5)P3, forming PI3P, PI4P, and
PI(3,4)P2, respectively. It is a very potent PI(3,4,5)P3
5-phosphatase. Its intracellular localization is chiefly
cytosolic, with pronounced perinuclear/Golgi
localization. INPP5E also has an N-terminal proline rich
domain (PRD) and a C-terminal CAAX motif. This protein
is expressed in a variety of tissues, including the
breast, brain, testis, and haemopoietic cells. It is
differentially expressed in several cancers, for
example, it is up-regulated in cervical cancer and
down-regulated in stomach cancer. It is a candidate
target for therapeutics of obesity and related
disorders, as it is expressed in the hypothalamus, and
following insulin stimulation, it undergoes tyrosine
phosphorylation, associates with insulin receptor
substrate-1, -2, and PI3-kinase, and become active as a
5-phosphatase. INPP5E may play a role, along with other
5-phosphatases SHIP2 and SKIP, in regulating glucose
homoeostasis and energy metabolism. Mice deficient in
INPPE5 develop a multi-organ disorder associated with
structural defects of the primary cilium.

5-phosphatase (INPP5c) domain of SH2 domain containing
inositol polyphosphate 5-phosphatase-1 and related
proteins. This subfamily contains the INPP5c domain of
SHIP1 (SH2 domain containing inositol polyphosphate
5-phosphatase-1, also known as SHIP/INPP5D) and related
proteins. It belongs to a family of Mg2+-dependent
inositol polyphosphate 5-phosphatases, which hydrolyze
the 5-phosphate from the inositol ring of various
5-position phosphorylated phosphoinositides (PIs) and
inositol phosphates (IPs), and to the large EEP
(exonuclease/endonuclease/phosphatase) superfamily that
contains functionally diverse enzymes that share a
common catalytic mechanism of cleaving phosphodiester
bonds. SHIP1's enzymic activity is restricted to
phosphatidylinositol 3,4,5-trisphosphate [PI (3,4,5)P3]
and inositol-1,3,4,5- polyphosphate [I(1,3,4,5)P4]. It
converts these two phosphoinositides to
phosphatidylinositol 3,4-bisphosphate [PI (3,4)P2] and
inositol-1,3,4-polyphosphate [I(1,3,4)P3], respectively.
SHIP1 is a negative regulator of cell growth and plays a
major part in mediating the inhibitory signaling in B
cells; it is predominantly expressed in hematopoietic
cells. In addition to this INPP5c domain, SHIP1 has an
N-terminal SH2 domain, two NPXY motifs, and a C-terminal
proline-rich region (PRD). SHIP1's phosphorylated NPXY
motifs interact with proteins with phosphotyrosine
binding (PTB) domains, and facilitate the translocation
of SHIP1 to the plasma membrane to hydrolyze
PI(3,4,5)P3. SHIP1 generally acts to oppose the activity
of phosphatidylinositol 3-kinase (PI3K). It acts as a
negative signaling molecule, reducing the levels of
PI(3,4,5)P3, thereby removing the latter as a
membrane-targeting signal for PH domain-containing
effector molecules. SHIP1 may also, in certain contexts,
amplify PI3K signals. SHIP1 and SHIP2 have little
overlap in their in vivo functions.

5-phosphatase (INPP5c) domain of SH2 domain containing
inositol polyphosphate 5-phosphatase-1 and -2, and
related proteins. This subfamily contains the INPP5c
domain of SHIP1 (SH2 domain containing inositol

SHIP/INPP5D), and SHIP2 (also known as INPPL1). It
belongs to a family of Mg2+-dependent inositol

contains functionally diverse enzymes that share a
common catalytic mechanism of cleaving phosphodiester

of the PI, phosphatidylinositol 3,4,5-trisphosphate
[PI(3,4,5)P3], to phosphatidylinositol 3,4-bisphosphate
[PI(3,4)P2]. SHIP1 also converts inositol-1,3,4,5-
polyphosphate [I(1,3,4,5)P4] to
inositol-1,3,4-polyphosphate [I(1,3,4)P3]. SHIP1 and
SHIP2 have little overlap in their in vivo functions.
SHIP1 is a negative regulator of cell growth and plays a
major part in mediating the inhibitory signaling in B
cells; it is predominantly expressed in hematopoietic
cells. SHIP2 is as an inhibitor of the insulin signaling
pathway, and is implicated in actin structure
remodeling, cell adhesion and cell spreading, receptor
endocytosis and degradation, and in the JIP1-mediated
JNK pathway. SHIP2 is widely expressed, most
prominently in brain, heart and in skeletal muscle. In
addition to this INPP5c domain, SHIP1 has an N-terminal
SH2 domain, two NPXY motifs, and a C-terminal
proline-rich region (PRD), while SHIP2 has an N-terminal
SH2 domain, a C-terminal proline-rich domain (PRD),
which includes a WW-domain binding motif (PPLP), an NPXY
motif, and a sterile alpha motif (SAM) domain. The gene
encoding SHIP2 is a candidate gene for conferring a
predisposition for type 2 diabetes.

>gnl|CDD|197333 cd09099, INPP5c_Synj2, Catalytic inositol polyphosphate
5-phosphatase (INPP5c) domain of synaptojanin 2. This
subfamily contains the INPP5c domains of human
synaptojanin 2 (Synj2) and related proteins. It belongs
to a family of Mg2+-dependent inositol polyphosphate
5-phosphatases, which hydrolyze the 5-phosphate from the
inositol ring of various 5-position phosphorylated
phosphoinositides (PIs) and inositol phosphates (IPs),
and to the large EEP
(exonuclease/endonuclease/phosphatase) superfamily that
contains functionally diverse enzymes that share a
common catalytic mechanism of cleaving phosphodiester
bonds. Synj2 can hydrolyze phosphatidylinositol
diphosphate (PIP2) to phosphatidylinositol phosphate
(PIP). In addition to this INPP5c domain, these proteins
contain an N-terminal Sac1-like domain; the Sac1 domain
can dephosphorylate a variety of phosphoinositides in
vitro. Synj2 occurs as multiple alternative splice
variants in various tissues. These variants share the
INPP5c domain and the Sac1 domain. Synj2A is recruited
to the mitochondria via its interaction with OMP25, a
mitochondrial outer membrane protein. Synj2B is found at
nerve terminals in the brain and at the spermatid
manchette in testis. Synj2B undergoes further
alternative splicing to give 2B1 and 2B2. In
clathrin-mediated endocytosis, Synj2 participates in the
formation of clathrin-coated pits, and perhaps also in
vesicle decoating. Rac1 GTPase regulates the
intracellular localization of Synj2 forms, but not
Synj1. Synj2 may contribute to the role of Rac1 in cell
migration and invasion, and is a potential target for
therapeutic intervention in malignant tumors.

>gnl|CDD|197335 cd09101, INPP5c_SHIP2-INPPL1, Catalytic inositol polyphosphate
5-phosphatase (INPP5c) domain of SH2 domain containing
inositol 5-phosphatase-2 and related proteins. This
subfamily contains the INPP5c domain of SHIP2 (SH2
domain containing inositol 5-phosphatase-2, also called
INPPL1) and related proteins. It belongs to a family of
Mg2+-dependent inositol polyphosphate 5-phosphatases,
which hydrolyze the 5-phosphate from the inositol ring
of various 5-position phosphorylated phosphoinositides
(PIs) and inositol phosphates (IPs), and to the large
EEP (exonuclease/endonuclease/phosphatase) superfamily
that contains functionally diverse enzymes that share a
common catalytic mechanism of cleaving phosphodiester
bonds. SHIP2 catalyzes the dephosphorylation of the PI,
phosphatidylinositol 3,4,5-trisphosphate [PI(3,4,5)P3],
to phosphatidylinositol 3,4-bisphosphate [PI(3,4)P2].
SHIP2 is widely expressed, most prominently in brain,
heart and in skeletal muscle. SHIP2 is an inhibitor of
the insulin signaling pathway. It is implicated in actin
structure remodeling, cell adhesion and cell spreading,
receptor endocytosis and degradation, and in the
JIP1-mediated JNK pathway. Its interacting partners
include filamin/actin, p130Cas, Shc, Vinexin,
Interesectin 1, and c-Jun NH2-terminal kinase
(JNK)-interacting protein 1 (JIP1). A large variety of
extracellular stimuli appear to lead to the tyrosine
phosphorylation of SHIP2, including epidermal growth
factor (EGF), platelet-derived growth factor (PDGF),
insulin, macrophage colony-stimulating factor (M-CSF)
and hepatocyte growth factor (HGF). SHIP2 is localized
to the cytosol in quiescent cells; following growth
factor stimulation and /or cell adhesion, it relocalizes
to membrane ruffles. In addition to this INPP5c domain,
SHIP2 has an N-terminal SH2 domain, a C-terminal
proline-rich domain (PRD), which includes a WW-domain
binding motif (PPLP), an NPXY motif and a sterile alpha
motif (SAM) domain. The gene encoding SHIP2 is a
candidate for conferring a predisposition for type 2
diabetes; it has been suggested that suppression of
SHIP2 may be of benefit in the treatment of obesity and
thereby prevent type 2 diabetes. SHIP2 and SHIP1 have
little overlap in their in vivo functions.
