This Anti-phospho Grb10 (Ser503) Antibody is validated for use in Peptide Inhibition Assay, Western Blotting for the detection of phospho Grb10 (Ser503).

Peptide Inhibition Assay Analysis: 1 µg/mL from a representative lot detected phospho-Grb10 (Ser503) on 10 µg of embryonic fibroblast cell lysate + non-phospho-Grb10 (Ser503) peptide. However, the antibody was inhibited when incubated with a phospho-Grb10 (Ser503) peptide.

General description

Grb10 (insulin receptor-binding protein Grb-IR) is a ubiquitous adapter protein which is expressed in both fetal and adult tissues. It is a multidomain protein that interacts with a wide array of cellular targets; the PH domain allows interaction with several subtypes of phosphoinositides; the Ras-associating domain binds a wide variety of Ras GTPases; and the SH domain facilitates binding to membrane-bound tyrosine kinase receptors which link Grb10 to different signaling pathways. Most notably, Grb10 associates with the insulin receptor at phosphotyrosine residues via its C-terminal BPS (between PH and SH) domain and inhibits the enzymatic activity of the insulin receptor. Grb10 also acts downstream of the insulin receptor pathway to inhibit activation of AKT-1. In addition, Grb10 suppresses Wnt signalling by binding to the low-density lipoprotein receptor. In fetal tissues, Grb10 may inhibit growth and placental size.
