Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human PDGFRb sequence peptide Cat. No.: PE-01BBX99
Antibody Immunogen Sequence: CSQEPPQEMAKAQDGT

Antibody Immunogen Description: Corresponds to amino acid residues S66 to T80; N-terminus

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.

Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: PDGFRB is a receptor protein-tyrosine kinase in the TK family and PDGFR group. It acts as a cell surface receptor for PDGFA, PDGFB, and PDGFC. It is highly expressed and widely distributed in most tested human tissues. Orthologues are highly conserved in mammals and birds. PDGFRB is activated by binding platelet-derived growth factor. Autophosphorylation of Y579, Y581, Y716, Y740 and Y751 increases PDGFRB kinase activity. Protein interactions are induced with phosphorylation of Y716 (with Grb2 & Grb7), Y579 (with PIK3R1, PLCg1, RasGAP, Shc1 & Src), Y581 (with PIK3R1, PLCg1, RasGAP & Src), Y740 and Y751 (with PIK3C2A, PIK3CA, PIK3R1 & Shc1), Y763 (with SHP2), Y771 (with RasGAP and Shc1), Y775 (with Grb7), Y1009 (with Cbl, PLCg1, SH3KBP1 & SHP2), and Y1021 (with PLCg1). Phosphorylation of Y1009 inhibits binding to PIK3R1 and RasGAP. PDGFRb-deficient mice are hemorrhagic, severely anemic and exhibit a defect in kidney glomeruli function. PDGFRb expression and activity is elevated in several cancers and inhibition of PDGFRb activity blocks progression of renal carcinoma in an animal model. The active form of the protein kinase normally acts to promote tumour cell proliferation. R561C and P660T mutations in PDGFRB are associated with myofibromatosis, infantile 1. A translocation between chromosomes 5 and 12 that fuses this gene to that of the translocation, results in chronic myeloproliferative disorder with eosinophilia. PDGFRB has also been linked with myeloproliferative disorders, metastatic medulloblastomas, breast carcinomas and gastric adenocarcinomas. Insertional mutagenesis studies in mice also support a role for this protein kinase in mouse cancer oncogenesis.
