background	Although EphB3 expression is down-regulated in colorectal cancer (CRC) cells compared with normal intestinal epithelial cells.EphB3 is down-regulated in CRC compared to normal mucosa. Hypermethylation of CpG island is contributed to downregulation of EphB3 in CRC. EphB3 expression in tumor cells may be a useful prognostic indicator for patients with CRC.
molecular weight	The protein has a predicted MW of 58.4 kDa. Due to glycosylation, the protein migrates to 65-70 kDa based on Tris-Bis PAGE result.
available size	100 µg, 500 µg
endotoxin	Less than 1EU per μg by the LAL method.

Protein names Ephrin type-B receptor 3 (EC 2.7.10.1) (Developmental kinase 5) (mDK-5) (Tyrosine-protein kinase receptor SEK-4)
Gene names Ephb3,Ephb3 Etk2 Mdk5 Sek4
Protein family Protein kinase superfamily, Tyr protein kinase family, Ephrin receptor subfamily
Mass 10090Da
Function Receptor tyrosine kinase which binds promiscuously transmembrane ephrin-B family ligands residing on adjacent cells, leading to contact-dependent bidirectional signaling into neighboring cells. The signaling pathway downstream of the receptor is referred to as forward signaling while the signaling pathway downstream of the ephrin ligand is referred to as reverse signaling. Generally has an overlapping and redundant function with EPHB2. Like EPHB2, functions in axon guidance during development regulating for instance the neurons forming the corpus callosum and the anterior commissure, 2 major interhemispheric connections between the temporal lobes of the cerebral cortex. In addition to its role in axon guidance also plays an important redundant role with other ephrin-B receptors in development and maturation of dendritic spines and the formation of excitatory synapses. Controls other aspects of development through regulation of cell migration and positioning. This includes angiogenesis, palate development and thymic epithelium development for instance. Forward and reverse signaling through the EFNB2/EPHB3 complex also regulate migration and adhesion of cells that tubularize the urethra and septate the cloaca. Finally, plays an important role in intestinal epithelium differentiation segregating progenitor from differentiated cells in the crypt.
Catalytic activity BINDING 634..642; /ligand="ATP"; /ligand_id="ChEBI:CHEBI:30616"; /evidence="ECO:0000255\|PROSITE-ProRule:PRU00159"; BINDING 660; /ligand="ATP"; /ligand_id="ChEBI:CHEBI:30616"; /evidence="ECO:0000255\|PROSITE-ProRule:PRU00159"
Subellular location Cell membrane ; Single-pass type I membrane protein. Cell projection, dendrite .
Tissues Expressed in cells of the retinal ganglion cell layer during retinal axon guidance to the optic disk. Expressed by Paneth and progenitor cells in the crypts of the intestinal epithelium (at protein level). Expressed in myogenic progenitor cells (PubMed:27446912).
Structure Heterotetramer upon binding of the ligand. The heterotetramer is composed of an ephrin dimer and a receptor dimer. Oligomerization is probably required to induce biological responses (By similarity).
Post-translational modification Phosphorylated. Autophosphorylates upon ligand-binding. Autophosphorylation on Tyr-609 is required for interaction with SH2 domain-containing proteins (By similarity).; Ubiquitinated by RNF186, mainly through 'Lys-48' and 'Lys-63'-linked polyubiquitin chains.
