>gnl|CDD|188887 cd09488, SAM_EPH-R, SAM domain of EPH family of tyrosine kinase
receptors. SAM (sterile alpha motif) domain of EPH
(erythropoietin-producing hepatocyte) family of
receptor tyrosine kinases is a C-terminal signal
transduction module located in the cytoplasmic region
of these receptors. SAM appears to mediate cell-cell
initiated signal transduction via binding proteins to a
conserved tyrosine that is phosphorylated. In some
cases the SAM domain mediates
homodimerization/oligomerization and plays a role in
the clustering process necessary for signaling. EPH
kinases are the largest family of receptor tyrosine
kinases. They are classified into two groups based on
their abilities to bind ephrin-A and ephrin-B ligands.
The EPH receptors are involved in regulation of cell
movement, shape, and attachment during embryonic
development; they control cell-cell interactions in the
vascular, nervous, epithelial, and immune systems, and
in many tumors. They are potential molecular markers
for cancer diagnostics and potential targets for cancer
therapy.

kinase receptors. SAM (sterile alpha motif) domain of
EPH-A7 subfamily of receptor tyrosine kinases is a
C-terminal potential protein-protein interaction
domain. This domain is located in the cytoplasmic
region of EPH-A7 receptors and appears to mediate
cell-cell initiated signal transduction. EphA7 was
found expressed in human embryonic stem (ES) cells,
neural tissues, kidney vasculature. EphA7 knockout mice
show decrease in cortical progenitor cell death at
mid-neurogenesis and significant increase in cortical
size. EphA7 may be involved in the pathogenesis and
development of different cancers; in particular, EphA7
was found upregulated in glioblastoma and downregulated
in colorectal cancer and gastric cancer. Thus, it is a
potential molecular marker and/or therapy target for
these types of cancers.

kinase receptors. SAM (sterile alpha motif) domain of
EPH-A8 subfamily of receptor tyrosine kinases is a
C-terminal potential protein-protein interaction
domain. This domain is located in the cytoplasmic
region of EPH-A8 receptors and appears to mediate
cell-cell initiated signal transduction. EPH-A8
receptors are involved in ligand dependent (ephirin A2,
A3, A5) regulation of cell adhesion and migration, and
in ligand independent regulation of neurite outgrowth
in neuronal cells. They perform signaling in kinase
dependent and kinase independent manner. EPH-A8
receptors are known to interact with a number of
different proteins including PI 3-kinase and AIDA1-like
subfamily SAM repeat domain containing proteins.
However other domains (not SAM) of EPH-A8 receptors are
involved in these interactions.

kinase receptors. SAM (sterile alpha motif) domain of
EPH-B6 subfamily of receptor tyrosine kinases is a
C-terminal potential protein-protein interaction
domain. This domain is located in the cytoplasmic
region of EPH-B6 receptors and appears to mediate
cell-cell initiated signal transduction. Receptors of
this type are highly expressed in embryo and adult
nervous system, in thymus and also in T-cells. They are
involved in regulation of cell adhesion and migration.
(EPH-B6 receptor is unusual; it fails to show catalytic
activity due to alteration in kinase domain). EPH-B6
may be considered as a biomarker in some types of
tumors; EPH-B6 activates MAP kinase signaling in lung
adenocarcinoma, suppresses metastasis formation in
non-small cell lung cancer, and slows invasiveness in
some breast cancer cell lines.

kinase receptors. SAM (sterile alpha motif) domain of
EPH-A5 subfamily of receptor tyrosine kinases is a
C-terminal potential protein-protein interaction
domain. This domain is located in the cytoplasmic
region of EPH-A5 receptors and appears to mediate
cell-cell initiated signal transduction. Eph-A5 gene is
almost exclusively expressed in the nervous system.
Murine EPH-A5 receptors participate in axon guidance
during embryogenesis and play a role in the adult
synaptic plasticity, particularly in neuron-target
interactions in multiple neural circuits. Additionally
EPH-A5 receptors and its ligand ephrin A5 regulate
dopaminergic axon outgrowth and influence the formation
of the midbrain dopaminergic pathways. EphA5 gene
expression was found decreased in a few different
breast cancer cell lines, thus it might be a potential
molecular marker for breast cancer carcinogenesis and
progression.

suggested that SAM is an evolutionarily conserved
protein binding domain that is involved in the
regulation of numerous developmental processes in
diverse eukaryotes. The SAM domain can potentially

kinase receptors. SAM (sterile alpha motif) domain of
EPH-B1 subfamily of receptor tyrosine kinases is a
C-terminal potential protein-protein interaction
domain. This domain is located in the cytoplasmic
region of EPH- B1 receptors. In human vascular
endothelial cells it appears to mediate cell-cell
initiated signal transduction via the binding of the
adaptor protein GRB10 (growth factor) through its SH2
domain to a conserved tyrosine that is phosphorylated.
EPH-B1 receptors play a role in neurogenesis, in
particular in regulation of proliferation and migration
of neural progenitors in the hippocampus and in corneal
neovascularization; they are involved in converting the
crossed retinal projection to ipsilateral retinal
projection. They may be potential targets in
angiogenesis-related disorders.

EPH-B2 subfamily of receptor tyrosine kinases is a
C-terminal potential protein-protein interaction
domain. This domain is located in the cytoplasmic
region of EPH-B2 receptors and appears to mediate
cell-cell initiated signal transduction. SAM domains of
this subfamily form homodimers/oligomers (in
head-to-head/tail-to-tail orientation); apparently such
clustering is necessary for signaling. EPH-B2 receptor
is involved in regulation of synaptic function; it is
needed for normal vestibular function, proper formation
of anterior commissure, control of cell positioning,
and ordered migration in the intestinal epithelium.
EPH-B2 plays a tumor suppressor role in colorectal
cancer. It was found to be downregulated in gastric
cancer and thus may be a negative biomarker for it.

kinase receptors. SAM (sterile alpha motif) domain of
EPH-A4 subfamily of receptor tyrosine kinases is a
C-terminal potential protein-protein interaction
domain. This domain is located in the cytoplasmic
region of EPH-A4 receptors and appears to mediate
cell-cell initiated signal transduction. SAM domains of
EPH-A4 receptors can form homodimers. EPH-A4 receptors
bind ligands such as erphirin A1, A4, A5. They are
known to interact with a number of different proteins,
including meltrin beta metalloprotease, Cdk5, and
EFS2alpha, however SAM domain doesn't participate in
these interactions. EPH-A4 receptors are involved in
regulation of corticospinal tract formation, in pathway
controlling voluntary movements, in formation of motor
neurons, and in axon guidance (SAM domain is not
required for axon guidance or for EPH-A4 kinase
signaling). In Xenopus embryos EPH-A4 induces loss of
cell adhesion, ventro-lateral protrusions, and severely
expanded posterior structures. Mutations in SAM domain
conserved tyrosine (Y928F) enhance the ability of
EPH-A4 to induce these phenotypes, thus supporting the
idea that the SAM domain may negatively regulate some
aspects of EPH-A4 activity. EphA4 gene was found
overexpressed in a number of different cancers
including human gastric cancer, colorectal cancer, and
pancreatic ductal adenocarcinoma. It is likely to be a
promising molecular target for the cancer therapy.

EPH-A1 subfamily of the receptor tyrosine kinases is a
C-terminal protein-protein interaction domain. This
domain is located in the cytoplasmic region of EPH-A1
receptors and appears to mediate cell-cell initiated
signal transduction. Activation of these receptors
leads to inhibition of cell spreading and migration in
a RhoA-ROCK-dependent manner. EPH-A1 receptors are
known to bind ILK (integrin-linked kinase) which is the
mediator of interactions between integrin and the actin
cytoskeleton. However SAM is not sufficient for this
interaction; it rather plays an ancillary role. SAM
domains of Eph-A1 receptors do not form homo/hetero
dimers/oligomers. EphA1 gene was found expressed widely
in differentiated epithelial cells. In a number of
different malignant tumors EphA1 genes are
downregulated. In breast carcinoma the downregulation
is associated with invasive behavior of the cell.

kinase receptors. SAM (sterile alpha motif) domain of
EPH-A3 subfamily of receptor tyrosine kinases is a
C-terminal putative protein-protein interaction domain.
This domain is located in the cytoplasmic region of
EPH-A3 receptors and appears to mediate cell-cell
initiated signal transduction. EPH-A3 receptors bind
SH2/SH3 containing adaptor protein Nck1 and this
adaptor is a key factor in EPH-A3 mediated signaling.
However SAM domain is not implemented in this
interaction. Activation of EPH-A3 receptors inhibits
outgrowth and cell migration. Mutations in SAM domain
may play a role in development of hepatocellular
carcinoma. Expression of EPH-A3 is associated with
lymphocytic leukemia and defines the subset of
rhabdomyosarcoma tumors. EPH-A3 receptors are
attractive targets for drug design.

(2-C-methyl-D-erythritol-2,4-cyclodiphosphate synthase),
encoded by the ispF gene, catalyzes the formation of
2-C-methyl-D-erythritol 2,4-cyclodiphosphate (MEC) in
the non-mevalonate deoxyxylulose (DOXP) pathway for
isoprenoid biosynthesis. This pathway is present in
bacteria, plants and some protozoa but is distinct from
that used by mammals and Archaea. MECDP_synthase forms
a homotrimer, carrying three active sites, each of which
is formed in a cleft between pairs of subunits.
