Antibody Immunogen Source: Human EphA2 sequence peptide Cat. No.: PE-04ALW99
Antibody Immunogen Sequence: LKT(pY)VDP(bA)C
Antibody Immunogen Description: Corresponds to amino acid residues L585 to P591; in the EphA2-TM domain located prior to the kinase catalytic domain. One of the major in vivo sites of phosphorylation in EphA2.Y588 phosphorylation stimulates phosphotransferase activity and regulates cell adhesion, cell differentiation, cell motility and molecular association, including inducing interaction with Nck1, VAV2 and VAV3. One of the major in vivo sites of phosphorylation in EphA2 (≥655 reports from high throughput mass spectrometry studies recorded in PhosphoSitePlus). EphA2 is known to be phosphorylated at this site in vitro by EphA2.
Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.This antibody was also subject to negative purification over phosphotyrosine-agarose.
Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: EphA2 is a 130 kDa protein-tyrosine kinase of the TK group and Eph family. It is a receptor that displays promiscuous binding to membrane-bound ligands of the ephrin-A family on adjacent cells. It is activated by binding ephrin-A1, A2, A3, A4 or A5, and subsequent dimerization. It features a single cytoplasmic kinase domain and an extracellular region with a Cys-rich domain and two fibronectin type III repeats. Phosphorylation of Tyr-735 increases phosphotranserase activity and interaction with PIK3R1. EphA2 activation regulates integrin-dependent adhesion, cellular migration, proliferation, and differentiation. It is present at low levels in normal adult epithelial cells, and primarily found on the plasma membrane and at cell junctions. EphA2 also participates in bone remodeling by directly regulating both osteoclastogenesis and osteoblastogenesis. EphA2 may be an oncoprotein (OP). Significantly elevated EphA2 expression has been observed in many types of human cancer and appears to be involved in mediating communication between RAS-PI3K/Akt and RAS-MAPK intracellular signalling pathways, which are both known to promote tumorigenesis. EphA2 is required for UV-radiation induced apoptosis. UV-radiation is a potent carcinogen responsible for the development of melanoma. However, further characterization of melanoma cell lines revealed either a pro-apoptotic or anti-apoptotic role for EphA2 dependent upon the cellular context. Additionally, studies performed in breast cancer cell lines revealed a link between EphA2 expression levels and changes in cytoskeletal morphology and the recruitment of disintegrin and metalloprotease-10 (MMP10) enzymes, which also implicates a role for theEphA2 protein in the promotion of tumour invasion and metastasis. It also acts as a receptor for KSHV and Hepatitis C virus entry into host cells. This description may include information annotated by UniProt and/or Google AI.
