Scientific Data Images for Human/Mouse/Rat GRB2 Antibody

Detection of Human/Mouse/Rat GRB2 antibody by Western Blot.

Detection of Human/Mouse/Rat GRB2 by Western Blot.

Western blot shows lysates of Jurkat human acute T cell leukemia cell line, Balb/3T3 mouse embryonic fibroblast cell line and NRK rat normal kidney cell line. PVDF membrane was probed with 0.5 µg/mL of Human/Mouse/Rat GRB2 Monoclonal Antibody (Catalog # MAB3846) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for GRB2 at approximately 30 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: GRB2

GRB2 (growth factor receptor-bound protein 2), an adaptor protein involved in signal transduction, contains a central SH2 domain flanked by two SH3 domains. The SH2 domain binds to phosphotyrosine residues in RTKs such as PDGF and EGF, non-RTKs such as Bcr/Abl and FAK, and docking proteins such as FRS-2 and Gab1. The SH3 domains associate with proline rich motifs on the guanine nucleotide releasing factor, Sos, stimulating GTP binding to Ras, which in turn activates MAPK and other signaling pathways. GRB2 also participates in the endocytosis of EGFR through its recruitment of Cbl. Tyrosine phosphorylation of GRB2 SH3 domains reduces binding to Sos and negatively regulates downstream signaling pathways including Ras, JNK and MAPK.
