>gnl|CDD|233149 TIGR00845, caca, sodium/calcium exchanger 1. The Ca2+:Cation
Antiporter (CaCA) Family (TC 2.A.19)Proteins of the CaCA
family are found ubiquitously, having been identified in
animals, plants, yeast, archaea and widely divergent
bacteria.All of the characterized animal proteins
catalyze Ca2+:Na+ exchange although some also transport
K+. The NCX1 plasma membrane protein exchanges 3 Na+ for
1 Ca2+. The E. coli ChaA protein catalyzes Ca2+:H+
antiport but may also catalyze Na+:H+ antiport. All
remaining well-characterized members of the family
catalyze Ca2+:H+ exchange.This model is specific for the
eukaryotic sodium ion/calcium ion exchangers of the Caca
family [Transport and binding proteins, Other].

family of sodium/calcium exchanger integral membrane
proteins. This family covers the integral membrane
regions of the proteins. Sodium/calcium exchangers
regulate intracellular Ca2+ concentrations in many
cells; cardiac myocytes, epithelial cells, neurons
retinal rod photoreceptors and smooth muscle cells. Ca2+
is moved into or out of the cytosol depending on Na+
concentration. In humans and rats there are 3 isoforms;
NCX1 NCX2 and NCX3.

are included within the larger pfam03102 (NeuB) family.
NeuB itself (TIGR03569) is involved in the biosynthesis
of neuraminic acid by the condensation of
phosphoenolpyruvate (PEP) with N-Acetyl-D-Mannosamine.
In an analagous reaction, this enzyme, PseI , condenses
PEP with 6-deoxy-beta-L-AltNAc4NAc to generate
pseudaminic acid.

N-acetylneuraminic acid (Neu5Ac) synthase. It catalyzes
the direct formation of Neu5Ac (the most common sialic
acid) by condensation of phosphoenolpyruvate (PEP) and
N-acetylmannosamine (ManNAc). This reaction has only
been observed in prokaryotes; eukaryotes synthesise the

instead of ManNAc. Such eukaryotic enzymes are not
present in this family. This family also contains SpsE

>gnl|CDD|132785 cd06875, PX_IRAS, The phosphoinositide binding Phox Homology
domain of the Imidazoline Receptor Antisera-Selected.
The PX domain is a phosphoinositide binding (PI) module
present in many proteins with diverse functions such as
cell signaling, vesicular trafficking, protein sorting,
and lipid modification, among others. Imidazoline
Receptor Antisera-Selected (IRAS), also called
nischarin, contains an N-terminal PX domain, leucine
rich repeats, and a predicted coiled coil domain. The
PX domain of IRAS binds to
phosphatidylinositol-3-phosphate in membranes. Together
with the coiled coil domain, it is essential for the
localization of IRAS to endosomes. IRAS has been shown
to interact with integrin and inhibit cell migration.
Its interaction with alpha5 integrin causes a
redistribution of the receptor from the cell surface to
endosomal structures, suggesting that IRAS may function
as a sorting nexin (SNX) which regulates the endosomal
trafficking of integrin. SNXs make up the largest group
among PX domain containing proteins. They are involved
in regulating membrane traffic and protein sorting in
the endosomal system. SNXs differ from each other in
PI-binding specificity and affinity, and the presence
of other protein-protein interaction domains, which
help determine subcellular localization and specific
function in the endocytic pathway.

threonine aspartase, a member of the Ntn hydrolase
superfamily and the type 2 asparaginase family. A
threonine residue acts as the active site nucleophile in
both endopeptidease and protease activities to cleave
polypeptide substrates after an aspartate residue. The
Taspase1 proenzyme undergoes autoproteolysis into alpha
and beta subunits. The N-terminal residue of the beta
subunit is a threonine which is the active catalytic
residue. The active enzyme is a heterotetramer.

Kinase, MAP kinase kinase 5. Protein kinases (PKs), MAP
kinase kinase 5 (MKK5) subfamily, catalytic (c) domain.
PKs catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine or tyrosine residues on
protein substrates. The MKK5 subfamily is part of a
larger superfamily that includes the catalytic domains
of other protein serine/threonine kinases, protein
tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. The mitogen-activated protein (MAP) kinase
signaling pathways are important mediators of cellular
responses to extracellular signals. The pathways involve
a triple kinase core cascade comprising of 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). MKK5, also referred to as MEK5, is a
dual-specificity PK that phosphorylates its downstream
target, extracellular signal-regulated kinase 5 (ERK5),
on specific threonine and tyrosine residues. MKK5 is
activated by MEKK2 and MEKK3 in response to mitogenic
and stress stimuli. The ERK5 cascade promotes cell
proliferation, differentiation, neuronal survival, and
neuroprotection. This cascade plays an essential role in
heart development. Mice deficient in either ERK5 or MKK5
die around embryonic day 10 due to cardiovascular
defects including underdevelopment of the myocardium. In
addition, MKK5 is associated with metastasis and
unfavorable prognosis in prostate cancer.
