They can be divided into two groups based on sequence similarity and on their preference for a subset of ligands: EphA receptors bind to a glycosylphosphatidylinositol-anchored ephrin A ligand; EphB receptors bind to ephrin B proteins that have a transmembrane and cytoplasmic domain (1,2). Research studies have shown that Eph receptors and ligands may be involved in many diseases including cancer (3). Both ephrin A and B ligands have dual functions. As RTK ligands, ephrins stimulate the kinase activity of Eph receptors and activate signaling pathways in receptor-expressing cells. The ephrin extracellular domain is sufficient for this function as long as it is clustered (4). The second function of ephrins has been described as \"reverse signaling\", whereby the cytoplasmic domain becomes tyrosine phosphorylated, allowing interactions with other proteins that may activate signaling pathways in the ligand-expressing cells (5). Various stimuli can induce tyrosine phosphorylation of ephrin B, including binding to EphB receptors, activation of Src kinase, and stimulation by PDGF and FGF (6). Tyr324 and Tyr327 have been identified as major phosphorylation sites of ephrin B1 (7). EphA2 is overexpressed in various tumor cells, and it has been suggested that EphA2 may promote malignancy. However, several studies demonstrate that EphA2 plays an important role in tumor suppression (8). The role of EphA2 in tumor development may depend upon regulation of its tyrosine kinase activity.\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nARCC2; CTPA; CTPP1; CTRCT6; ECK; EPH receptor A2; EPHA2; ephrin receptor EphA2; Ephrin type-A receptor 2; Epithelial cell kinase; epithelial cell receptor protein tyrosine kinase; protein tyrosine kinase; soluble EPHA2 variant 1; Tyrosine-protein kinase receptor ECK\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R Mk\nSENSITIVITY: Endogenous\nMW (kDa): 125\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46799865610409,"sku":"6997S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-6997s","provider":"Iright","version":"1.0","type":"link"}
