>gnl|CDD|199844 cd03860, M14_CP_A-B_like, Peptidase M14 carboxypeptidase subfamily
A/B-like. The Peptidase M14 Carboxypeptidase (CP) A/B
subfamily is one of two main M14 CP subfamilies defined
by sequence and structural homology, the other being the
N/E subfamily. CPs hydrolyze single, C-terminal amino
acids from polypeptide chains. They have a recognition
site for the free C-terminal carboxyl group, which is a
key determinant of specificity. Enzymes belonging to the
A/B subfamily are normally synthesized as inactive
precursors containing preceding signal peptide, followed
by a globular N-terminal pro-region linked to the
enzyme; these proenzymes are called
procarboxypeptidases. The A/B enzymes can be further
divided based on their substrate specificity;
Carboxypeptidase A-like (CPA-like) enzymes favor
hydrophobic residues while carboxypeptidase B-like
(CPB-like) enzymes only cleave the basic residues lysine
or arginine. There are nine members in the A/B family:
CPA1, CPA2, CPA3, CPA4, CPA5, CPA6, CPB, CPO and CPU.
CPA1, CPA2 and CPB are produced by the pancreas. The A
forms have slightly different specificities, with CPA1
preferring aliphatic and small aromatic residues, and
CPA2 preferring the bulkier aromatic side chains. CPA3
is found in secretory granules of mast cells and
functions in inflammatory processes. CPA4 is detected in
hormone-regulated tissues, and is thought to play a role
in prostate cancer. CPA5 is present in discrete regions
of pituitary and other tissues, and cleaves aliphatic
C-terminal residues. CPA6 is highly expressed in
embryonic brain and optic muscle, suggesting that it may
play a specific role in cell migration and axonal
guidance. CPU (also called CPB2) is produced and
secreted by the liver as the inactive precursor, PCPU,
commonly referred to as thrombin-activatable
fibrinolysis inhibitor (TAFI). Little is known about CPO
but it has been suggested to have specificity for acidic
residues.

Carboxypeptidase (CP) A (CPA) belongs to the A/B
subfamily of the M14 family of metallocarboxypeptidases
(MCPs). The M14 family are zinc-binding CPs which
hydrolyze single, C-terminal amino acids from

(PCPA) is produced by the exocrine pancreas and stored
as a stable zymogen in the pancreatic granules until
secretion into the digestive tract occurs. This
subfamily includes CPA1, CPA2 and CPA4 forms. Within
these A forms, there are slightly different

procarboxypeptidase U or PCPB2, commonly referred to as
thrombin-activatable fibrinolysis inhibitor (TAFI). It
circulates in plasma as a zymogen bound to plasminogen,
and the active enzyme, TAFIa, inhibits fibrinolysis. It
is highly regulated, increased TAFI concentrations are
thought to increase the risk of thrombosis and coronary
artery disease by reducing fibrinolytic activity while
low TAFI levels have been correlated with chronic liver
disease.

>gnl|CDD|199843 cd03859, M14_CPT, Peptidase M14 Carboxypeptidase T subfamily.
Peptidase M14-like domain of carboxypeptidase (CP) T
(CPT), CPT belongs to the M14 family of
metallocarboxypeptidases (MCPs). The M14 family are
zinc-binding CPs which hydrolyze single, C-terminal
amino acids from polypeptide chains, and have a
recognition site for the free C-terminal carboxyl group,
which is a key determinant of specificity. CPT has
moderate similarity to CPA and CPB, and exhibits
dual-substrate specificity by cleaving C-terminal
hydrophobic amino acid residues like CPA and C-terminal
positively charged residues like CPB. CPA and CPB are
M14 family peptidases but do not belong to this CPT
group. The substrate specificity difference between CPT
and CPA and CPB is ascribed to a few amino acid
substitutions at the substrate-binding pocket while the
spatial organization of the binding site remains the
same as in all Zn-CPs. CPT has increased thermal
stability in presence of Ca2+ ions, and two disulfide
bridges which give an additional stabilization factor.

>gnl|CDD|199853 cd03872, M14_CPA6, Peptidase M14 carboxypeptidase subfamily
A/B-like; Carboxypeptidase A6 subgroup.
Carboxypeptidase (CP) A6 (CPA6, also known as CPAH; EC
3.4.17.1), belongs to the carboxypeptidase A/B subfamily
of the M14 family of metallocarboxypeptidases (MCPs).
The M14 family are zinc-binding CPs which hydrolyze
single, C-terminal amino acids from polypeptide chains,
and have a recognition site for the free C-terminal
carboxyl group, which is a key determinant of
specificity. CPA6 prefers large hydrophobic C-terminal
amino acids as well as histidine, while peptides with a
penultimate glycine or proline are very poorly cleaved.
Several neuropeptides are processed by CPA6, including
Met- and Leu-enkephalin, angiotensin I, and neurotensin.
CPA6 converts enkephalin and neurotensin into forms
known to be inactive toward their receptors, but
converts inactive angiotensin I into the biologically
active angiotensin II. Thus, CPA6 plays a possible role
in the regulation of neuropeptides in the extracellular
environment within the olfactory bulb where it is highly
expressed. It is also broadly expressed in embryonic
tissue, being found in neuronal tissues, bone, skin as
well as the lateral rectus eye muscle. A disruption in
the CPA6 gene is linked to Duane syndrome, a defect in
the abducens nerve/lateral rectus muscle connection.

divided based on their substrate specificity;
Carboxypeptidase A-like (CPA-like) enzymes favor
hydrophobic residues while carboxypeptidase B-like

N/E-like; Carboxypeptidase D, domain I subgroup. The
first carboxypeptidase (CP)-like domain of
Carboxypeptidase D (CPD; EC 3.4.17.22), domain I. CPD
differs from all other metallocarboxypeptidases in that
it contains multiple CP-like domains. CPD belongs to the
N/E-like subfamily of the M14 family of
metallocarboxypeptidases (MCPs).The M14 family are
zinc-binding CPs which hydrolyze single, C-terminal
amino acids from polypeptide chains, and have a
recognition site for the free C-terminal carboxyl group,
which is a key determinant of specificity. CPD is a
single-chain protein containing a signal peptide, three
tandem repeats of CP-like domains separated by short
bridge regions, followed by a transmembrane domain, and
a C-terminal cytosolic tail. The first two CP-like
domains of CPD contain all of the essential active site
and substrate-binding residues, the third CP-like domain
lacks critical residues necessary for enzymatic activity
and is inactive towards standard CP substrates. Domain I
is optimally active at pH 6.3-7.5 and prefers substrates
with C-terminal Arg, whereas domain II is active at pH
5.0-6.5 and prefers substrates with C-terminal Lys. This
Domain I family contains two contiguous surface
cysteines that may become palmitoylated and target the
enzyme to membranes, thus regulating intracellular
trafficking. CPD functions in the processing of proteins
that transit the secretory pathway, and is present in
all vertebrates as well as Drosophila. It is broadly
distributed in all tissue types. Within cells, CPD is
present in the trans Golgi network and immature
secretory vesicles, but is excluded from mature
vesicles. It is thought to play a role in the processing
of proteins that are initially processed by furin or
related endopeptidases present in the trans Golgi
network, such as growth factors and receptors. CPD is
implicated in the pathogenesis of lupus erythematosus
(LE), it is regulated by TGF-beta in various cell types
of murine and human origin and is significantly
down-regulated in CD14 positive cells isolated from
patients with LE. As down-regulation of CPD leads to
down-modulation of TGF-beta, CPD may have a role in a
positive feedback loop. In D. melanogaster, the CPD
variant 1B short (DmCPD1Bs) is necessary and sufficient
for viability of the fruit fly.

N/E-like. Carboxypeptidase (CP) N/E-like subfamily of
the M14 family of metallocarboxypeptidases (MCPs). The
M14 family are zinc-binding CPs which hydrolyze single,
C-terminal amino acids from polypeptide chains, and have
a recognition site for the free C-terminal carboxyl
group, which is a key determinant of specificity. The
N/E subfamily includes eight members, of which five
(CPN, CPE, CPM, CPD, CPZ) are considered enzymatically
active, while the other three are non-active (CPX1,
PCX2, ACLP/AEBP1) and lack the critical active site and
substrate-binding residues considered necessary for CP
activity. These non-active members may function as
binding proteins or display catalytic activity towards
other substrates. Unlike the A/B CP subfamily, enzymes
belonging to the N/E subfamily are not produced as
inactive precursors that require proteolysis to produce
the active form; rather, they rely on their substrate
specificity and subcellular compartmentalization to
prevent inappropriate cleavages that would otherwise
damage the cell. In addition, all members of the N/E
subfamily contain an extra C-terminal domain that is not
present in the A/B subfamily. This domain has structural
homology to transthyretin and other proteins and has
been proposed to function as a folding domain. The
active N/E enzymes fulfill a variety of cellular
functions, including prohormone processing, regulation
of peptide hormone activity, alteration of
protein-protein or protein-cell interactions and
transcriptional regulation.

uncharacterized subgroup of the M14 family of
metallocarboxypeptidases (MCPs). The M14 family are
zinc-binding carboxypeptidases (CPs) which hydrolyze
single, C-terminal amino acids from polypeptide chains,
and have a recognition site for the free C-terminal
carboxyl group, which is a key determinant of
specificity. Two major subfamilies of the M14 family,
defined based on sequence and structural homology, are
the A/B and N/E subfamilies. Enzymes belonging to the
A/B subfamily are normally synthesized as inactive
precursors containing preceding signal peptide, followed
by an N-terminal pro-region linked to the enzyme; these
proenzymes are called procarboxypeptidases. The A/B
enzymes can be further divided based on their substrate
specificity; Carboxypeptidase A-like (CPA-like) enzymes
favor hydrophobic residues while carboxypeptidase B-like
(CPB-like) enzymes only cleave the basic residues lysine
or arginine. The A forms have slightly different
specificities, with Carboxypeptidase A1 (CPA1)
preferring aliphatic and small aromatic residues, and
CPA2 preferring the bulky aromatic side chains. Enzymes
belonging to the N/E subfamily enzymes are not produced
as inactive precursors and instead rely on their
substrate specificity and subcellular
compartmentalization to prevent inappropriate cleavages.
They contain an extra C-terminal transthyretin-like
domain, thought to be involved in folding or formation
of oligomers. MCPs can also be classified based on
their involvement in specific physiological processes;
the pancreatic MCPs participate only in alimentary
digestion and include carboxypeptidase A and B (A/B
subfamily), while others, namely regulatory MCPs or the
N/E subfamily, are involved in more selective reactions,
mainly in non-digestive tissues and fluids, acting on
blood coagulation/fibrinolysis, inflammation and local
anaphylaxis, pro-hormone and neuropeptide processing,
cellular response and others. Another MCP subfamily,
is that of succinylglutamate desuccinylase

N/E-like; Carboxypeptidase D, domain III subgroup. The
third carboxypeptidase (CP)-like domain of
Carboxypeptidase D (CPD; EC 3.4.17.22), domain III. CPD
differs from all other metallocarboxypeptidases in that
it contains multiple CP-like domains. CPD belongs to the
N/E-like subfamily of the M14 family of
metallocarboxypeptidases (MCPs).The M14 family are
zinc-binding CPs which hydrolyze single, C-terminal
amino acids from polypeptide chains, and have a
recognition site for the free C-terminal carboxyl group,
which is a key determinant of specificity. CPD is a
single-chain protein containing a signal peptide, three
tandem repeats of CP-like domains separated by short
bridge regions, followed by a transmembrane domain, and
a C-terminal cytosolic tail. The first two CP-like
domains of CPD contain all of the essential active site
and substrate-binding residues, the third CP-like domain
lacks critical residues necessary for enzymatic activity
and is inactive towards standard CP substrates. Domain I
is optimally active at pH 6.3-7.5 and prefers substrates
with C-terminal Arg, whereas domain II is active at pH
5.0-6.5 and prefers substrates with C-terminal Lys. CPD
functions in the processing of proteins that transit the
secretory pathway, and is present in all vertebrates as
well as Drosophila. It is broadly distributed in all
tissue types. Within cells, CPD is present in the
trans-Golgi network and immature secretory vesicles, but
is excluded from mature vesicles. It is thought to play
a role in the processing of proteins that are initially
processed by furin or related endopeptidases present in
the trans-Golgi network, such as growth factors and
receptors. CPD is implicated in the pathogenesis of
lupus erythematosus (LE), it is regulated by TGF-beta in
various cell types of murine and human origin and is
significantly down-regulated in CD14 positive cells
isolated from patients with LE. As down -regulation of
CPD leads to down-modulation of TGF-beta, CPD may have a
role in a positive feedback loop.

specific for cleavage of the gamma-D-Glu-Dap bond of
free murein tripeptide; it may also cleave murein
tetrapeptide. MpaA has a different substrate specificity
and cellular role than endopeptidase I, ENP1 (ENP1 does
not belong to this group). MpaA works on free murein
peptide in the recycling pathway.

Pleckstrin homology (PH) domain. Human ORP1 has 2
forms, a long (ORP1L) and a short (ORP1S). ORP1L
contains 3 N-terminal ankyrin repeats, followed by a PH
domain, a FFAT motif (two phenylalanines in an acidic
tract), and a C-terminal OSBP-related domain. ORP1S is
truncated and contains only an OSBP-related domain.
ORP1L is proposed to function in motility and
distribution of late endosomes, autophagy, and
macrophage lipid metabolism. ORP1S is proposed to
function in vesicle transport from Golgi. Oxysterol
binding proteins are a multigene family that is
conserved in yeast, flies, worms, mammals and plants. In
general OSBPs and ORPs have been found to be involved in
the transport and metabolism of cholesterol and related
lipids in eukaryotes. They all contain a C-terminal
oxysterol binding domain, and most contain an N-terminal
PH domain. OSBP PH domains bind to membrane
phosphoinositides and thus likely play an important role
in intracellular targeting. They are members of the
oxysterol binding protein (OSBP) family which includes
OSBP, OSBP-related proteins (ORP), Goodpasture antigen
binding protein (GPBP), and Four phosphate adaptor
protein 1 (FAPP1). They have a wide range of purported
functions including sterol transport, cell cycle
control, pollen development and vessicle transport from
Golgi recognize both PI lipids and ARF proteins. 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.

Carboxypeptidase (CP) M (CPM) belongs to the N/E

hydrolyze single, C-terminal amino acids from

glycoprotein, bound to cell membranes via a

protein. It specifically removes C-terminal basic
residues such as lysine and arginine from peptides and
proteins. The highest levels of CPM have been found in
human lung and placenta, but significant amounts are
present in kidney, blood vessels, intestine, brain, and
peripheral nerves. CPM has also been found in soluble
form in various body fluids, including amniotic fluid,
seminal plasma and urine. Due to its wide distribution
in a variety of tissues, it is believed that it plays an
important role in the control of peptide hormones and
growth factor activity on the cell surface and in the
membrane-localized degradation of extracellular
proteins, for example it hydrolyses the C-terminal
arginine of epidermal growth factor (EGF) resulting in
des-Arg-EGF which binds to the EGF receptor (EGFR) with
an equal or greater affinity than native EGF. CPM is a
required processing enzyme that generates specific

binding proteins and cytosolic carboxypeptidases;
uncharacterized bacterial subgroup. A bacterial
subgroup of the Peptidase M14-like domain of Nna-1
(Nervous system Nuclear protein induced by Axotomy),
also known as ATP/GTP binding protein (AGTPBP-1) and
cytosolic carboxypeptidase (CCP)-like proteins. The
Peptidase M14 family of metallocarboxypeptidases are
zinc-binding carboxypeptidases (CPs) which hydrolyze
single, C-terminal amino acids from polypeptide chains,
and have a recognition site for the free C-terminal
carboxyl group, which is a key determinant of
specificity. Nna1-like proteins are active
metallopeptidases that are thought to act on cytosolic
proteins (such as alpha-tubulin in eukaryotes) to remove
a C-terminal tyrosine. Nna1-like proteins from the
different phyla are highly diverse, but they all contain
a unique N-terminal conserved domain right before the CP
domain. It has been suggested that this N-terminal
domain might act as a folding domain.

favor hydrophobic residues while carboxypeptidase B-like
(CPB-like) enzymes only cleave the basic residues lysine
or arginine. The A forms have slightly different
specificities, with Carboxypeptidase A1 (CPA1)
preferring aliphatic and small aromatic residues, and
CPA2 preferring the bulky aromatic side chains. Enzymes
belonging to the N/E subfamily enzymes are not produced
as inactive precursors and instead rely on their
substrate specificity and subcellular
compartmentalization to prevent inappropriate cleavage.
They contain an extra C-terminal transthyretin-like

their involvement in specific physiological processes;
the pancreatic MCPs participate only in alimentary

N/E-like; Carboxypeptidase E subgroup. Peptidase M14
Carboxypeptidase (CP) E (CPE, also known as
carboxypeptidase H, and enkephalin convertase; EC
3.4.17.10) belongs to the N/E subfamily of the M14
family of metallocarboxypeptidases (MCPs).The M14 family
are zinc-binding CPs which hydrolyze single, C-terminal
amino acids from polypeptide chains, and have a
recognition site for the free C-terminal carboxyl group,
which is a key determinant of specificity. CPE is an
important enzyme responsible for the proteolytic
processing of prohormone intermediates (such as
pro-insulin, pro-opiomelanocortin, or
pro-gonadotropin-releasing hormone) by specifically
removing C-terminal basic residues. In addition, it has
been proposed that the regulated secretory pathway (RSP)
of the nervous and endocrine systems utilizes
membrane-bound CPE as a sorting receptor. A naturally
occurring point mutation in CPE reduces the stability of
the enzyme and causes its degradation, leading to an
accumulation of numerous neuroendocrine peptides that
result in obesity and hyperglycemia. Reduced CPE enzyme
and receptor activity could underlie abnormal placental
phenotypes from the observation that CPE is
down-regulated in enlarged placentas of interspecific
hybrid (interspecies hybrid placental dysplasia, IHPD)
and cloned mice.

N/E-like; Carboxypeptidase N subgroup. Peptidase M14
Carboxypeptidase N (CPN, also known as kininase I,
creatine kinase conversion factor, plasma
carboxypeptidase B, arginine carboxypeptidase, and
protaminase; EC 3.4.17.3) is an extracellular
glycoprotein synthesized in the liver and released into
the blood, where it is present in high concentrations.
CPN belongs to the N/E subfamily of the M14 family of
metallocarboxypeptidases (MCPs).The M14 family are
zinc-binding carboxypeptidases (CPs) which hydrolyze
single, C-terminal amino acids from polypeptide chains,
and have a recognition site for the free C-terminal
carboxyl group, which is a key determinant of
specificity. CPN plays an important role in protecting
the body from excessive buildup of potentially
deleterious peptides that normally act as local
autocrine or paracrine hormones. It specifically removes
C-terminal basic residues. As CPN can cleave lysine more
avidly than arginine residues it is also called lysine
carboxypeptidase. CPN substrates include peptides found
in the bloodstream, such as kinins (e.g. bradykinin,
kalinin, met-lys-bradykinin), complement anaphylatoxins
and creatine kinase MM (CK-MM). By removing just one
amino acid, CPN can alter peptide activity and receptor
binding. For example Bradykinin, a nine-residue peptide
released from kiningen in response to tissue injury
which is inactivated by CPN, anaphylatoxins which are
regulated by CPN by the cleaving and removal of their
C-terminal arginines resulting in a reduction in their
biological activities of 10-100-fold, and creatine
kinase MM, a cytosolic enzyme that catalyzes the
reversible transfer of a phosphate group from ATP to
creatine, and is regulated by CPN by the cleavage of
C-terminal lysines. Like the other N/E subfamily
members, two surface loops surrounding the active-site
groove restrict access to the catalytic center, thus
restricting larger protein carboxypeptidase inhibitors
from inhibiting CPN.

subgroup. Peptidase M14-like domain of a functionally
uncharacterized subgroup of the M14 family of
metallocarboxypeptidases (MCPs). The M14 family are
zinc-binding carboxypeptidases (CPs) which hydrolyze
single, C-terminal amino acids from polypeptide chains,
and have a recognition site for the free C-terminal
carboxyl group, which is a key determinant of
specificity. Two major subfamilies of the M14 family,
defined based on sequence and structural homology, are
the A/B and N/E subfamilies. Enzymes belonging to the
A/B subfamily are normally synthesized as inactive
precursors containing preceding signal peptide, followed
by an N-terminal pro-region linked to the enzyme; these
proenzymes are called procarboxypeptidases. The A/B
enzymes can be further divided based on their substrate
specificity; Carboxypeptidase A-like (CPA-like) enzymes
favor hydrophobic residues while carboxypeptidase B-like
(CPB-like) enzymes only cleave the basic residues lysine
or arginine. The A forms have slightly different
specificities, with Carboxypeptidase A1 (CPA1)
preferring aliphatic and small aromatic residues, and
CPA2 preferring the bulky aromatic side chains. Enzymes
belonging to the N/E subfamily enzymes are not produced
as inactive precursors and instead rely on their
substrate specificity and subcellular
compartmentalization to prevent inappropriate cleavages.
They contain an extra C-terminal transthyretin-like
domain, thought to be involved in folding or formation
of oligomers. MCPs can also be classified based on
their involvement in specific physiological processes;
the pancreatic MCPs participate only in alimentary
digestion and include carboxypeptidase A and B (A/B
subfamily), while others, namely regulatory MCPs or the
N/E subfamily, are involved in more selective reactions,
mainly in non-digestive tissues and fluids, acting on
blood coagulation/fibrinolysis, inflammation and local
anaphylaxis, pro-hormone and neuropeptide processing,
cellular response and others. Another MCP subfamily,
is that of succinylglutamate desuccinylase
/aspartoacylase, which hydrolyzes N-acetyl-L-aspartate
(NAA), and deficiency in which is the established cause
of Canavan disease. Another subfamily (referred to as
subfamily C) includes an exceptional type of activity in
the MCP family, that of dipeptidyl-peptidase activity of

M14-like domain of carboxypeptidase (CP)-like protein X
(CPX), CPX forms a distinct subgroup of the N/E
subfamily of the M14 family of metallocarboxypeptidases
(MCPs). The M14 family are zinc-binding CPs which
hydrolyze single, C-terminal amino acids from
polypeptide chains, and have a recognition site for the
free C-terminal carboxyl group, which is a key
determinant of specificity. Proteins belonging to this
subgroup include CP-like protein X1 (CPX1), CP-like
protein X2 (CPX2), and aortic CP-like protein (ACLP)
and its isoform adipocyte enhancer binding protein-1
(AEBP1). AEBP1 is a truncated form of ACLP, which may
arise from alternative splicing of the gene. These
proteins are inactive towards standard CP substrates
because they lack one or more critical active site and
substrate-binding residues that are necessary for
activity. They may function as binding proteins rather
than as active CPs or display catalytic activity toward
other substrates. Proteins in this subgroup also
contain an N-terminal discoidin domain. The CP domain is
important for the function of AEBP1 as a transcriptional
repressor. AEBP1 is involved in several biological
processes including adipogenesis, macrophage cholesterol
homeostasis, and inflammation. In macrophages, AEBP1
promotes the expression of IL-6, TNF-alpha, MCP-1, and
iNOS whose expression is tightly regulated by NF-kappaB
activity. ACLP, a secreted protein that associates with
the extracellular matrix, is essential for abdominal
wall development and contributes to dermal wound
healing.

membranes and are found in proteins involved in membrane
dynamics and actin reorganization. Protein kinase C and
Casein kinase Substrate in Neurons (PACSIN) proteins,
also called Synaptic dynamin-associated proteins

membrane dynamics. Vetebrates harbor three isoforms with
distinct expression patterns and specific functions.
PACSIN 1 or Syndapin I is expressed specifically in the
brain and is localized in neurites and synaptic boutons.
It binds the brain-specific proteins dynamin I,
synaptojanin, synapsin I, and neural Wiskott-Aldrich
syndrome protein (nWASP), and functions as a link
between the cytoskeletal machinery and synaptic vesicle
endocytosis. PACSIN 1 interacts with huntingtin and may
be implicated in the neuropathology of Huntington's
disease. It contains an N-terminal F-BAR domain and a
C-terminal SH3 domain. F-BAR domains form banana-shaped
dimers with a positively-charged concave surface that
binds to negatively-charged lipid membranes. They can
induce membrane deformation in the form of long tubules.

>gnl|CDD|218177 pfam04615, Utp14, Utp14 protein. This protein is found to be part
of a large ribonucleoprotein complex containing the U3
snoRNA. Depletion of the Utp proteins impedes production
of the 18S rRNA, indicating that they are part of the
active pre-rRNA processing complex. This large RNP
complex has been termed the small subunit (SSU)
processome.

CRISPR (Clustered Regularly Interspaced Short
Palindromic Repeats) and associated Cas proteins
comprise a system for heritable host defense by
prokaryotic cells against phage and other foreign DNA;
Protein of this family often fused to HTH domain; Some
proteins could have an additional fusion with
RecB-family nuclease domain; Core domain appears to have
a Rossmann-like fold; loosely associated with CRISPR/Cas
systems; also known as NE0113 family.

>gnl|CDD|133118 cd06908, M14_AGBL4_like, Peptidase M14-like domain of ATP/GTP
binding protein AGBL-4 and related proteins. Peptidase
M14-like domain of ATP/GTP binding protein_like
(AGBL)-4, and related proteins. The Peptidase M14 family
of metallocarboxypeptidases are zinc-binding
carboxypeptidases (CPs) which hydrolyze single,
C-terminal amino acids from polypeptide chains, and have
a recognition site for the free C-terminal carboxyl
group, which is a key determinant of specificity. This
eukaryotic subgroup includes the human AGBL4 and the
mouse cytosolic carboxypeptidase (CCP)-6. ATP/GTP
binding protein (AGTPBP-1/Nna1)-like proteins are active
metallopeptidases that are thought to act on cytosolic
proteins such as alpha-tubulin, to remove a C-terminal
tyrosine. Mutations in AGTPBP-1/Nna1 cause Purkinje cell
degeneration (pcd). AGTPBP-1/Nna1 however does not
belong to this subgroup. AGTPBP-1/Nna1-like proteins
from the different phyla are highly diverse, but they
all contain a unique N-terminal conserved domain right
before the CP domain. It has been suggested that this
N-terminal domain might act as a folding domain.

>gnl|CDD|238578 cd01173, pyridoxal_pyridoxamine_kinase, Pyridoxal kinase plays a
key role in the synthesis of the active coenzyme
pyridoxal-5'-phosphate (PLP), by catalyzing the
phosphorylation of the precursor vitamin B6 in the
presence of Zn2+ and ATP. Mammals are unable to
synthesize PLP de novo and require its precursors in the
form of vitamin B6 (pyridoxal, pyridoxine, and
pyridoxamine) from their diet. Pyridoxal kinase encoding
genes are also found in many other species including
yeast and bacteria.
