EPHReceptor B2 (EPHB2) is a part of the transmembrane Eph receptor tyrosine kinasefamily (RTKs) which binds proteins of the Ephrin family on adjacent cells. Theinteraction leads to contact-dependent bidirectional signaling into neighboringcells. Hippocampal neurons can release vesicles containing full lengthEPHB2, and these are taken up by neighboring glial cells. EPHB2 takes part inthe guidance of commissural axons through the embryonic midline and regulatesdendritic spines development and maturation and stimulates the formation ofexcitatory synapses.
EPHB2 Human Recombinant produced in Sf9 Baculovirus cellsis a single, glycosylated polypeptide chain containing 533 amino acids (19-543a.a)and having a molecular mass of 59.1kDa (Molecular size on SDS-PAGE will appearat approximately 50-70kDa). EPHB2 is fused to a 8 amino acid His-tag at C-terminus& purified by proprietary chromatographic techniques.
| UniProt Protein Function: | EphB2: a receptor tyrosine kinase of the Eph family. A receptor for ephrin-B family members. Activated EphB2 recruits RasGAP, down-regulating the Ras-Erk signaling axis and neurite retraction. The Eph receptor tyrosine kinase family, the largest in the tyrosine kinase group, has fourteen members. They bind membrane-anchored ligands, ephrins, at sites of cell-cell contact, regulating the repulsion and adhesion of cells that underlie the establishment, maintenance, and remodeling of patterns of cellular organization. Eph signals are particularly important in regulating cell adhesion and cell migration during development, axon guidance, homeostasis and disease. EphA receptors bind to GPI-anchored ephrin-A ligands, while EphB receptors bind to ephrin-B proteins that have a transmembrane and cytoplasmic domain. Interactions between EphB receptor kinases and ephrin-B proteins transduce signals bidirectionally, signaling to both interacting cell types. Eph receptors and ephrins also regulate the adhesion of endothelial cells and are required for the remodeling of blood vessels. The ligand-activated form of EphB2 interacts with multiple proteins, including GTPase-activating protein (RASGAP) through its SH2 domain. Point mutations seen in prostate cancer. Overexpressed and required for migration of glioblastoma. Overexpressed and correlated with poor survival in breast cancer. Overexpression and loss of heterozygosity seen in colorectal cancers. Target for immunoconjugate drug therapy.Three splice-variant isoforms have been described. |

| NCBI Summary: | This gene encodes a member of the Eph receptor family of receptor tyrosine kinase transmembrane glycoproteins. These receptors are composed of an N-terminal glycosylated ligand-binding domain, a transmembrane region and an intracellular kinase domain. They bind ligands called ephrins and are involved in diverse cellular processes including motility, division, and differentiation. A distinguishing characteristic of Eph-ephrin signaling is that both receptors and ligands are competent to transduce a signaling cascade, resulting in bidirectional signaling. This protein belongs to a subgroup of the Eph receptors called EphB. Proteins of this subgroup are distinguished from other members of the family by sequence homology and preferential binding affinity for membrane-bound ephrin-B ligands. Allelic variants are associated with prostate and brain cancer susceptibility. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2015] |
