Insulin Receptor α (D3U7I) Rabbit mAb recognizes endogenous levels of total insulin receptor α chain.
Human, Mouse, Rat
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Asn170 of human insulin receptor protein.
Insulin receptor (InsR) is a heterodimeric membrane receptor tyrosine kinase. It is comprised of an extracellular α-subunit, containing the ligand binding domain, and a β-subunit containing an extracellular domain, a transmembrane domain and a cytoplasmic tyrosine kinase domain (1). Binding of insulin to InsR results in receptor autophosphorylation, and subsequent tyrosine kinase activation (2). This provides a docking site for various adaptor molecules, including insulin-receptor substrate (IRS), Gab and Shc, phosphorylation of which promotes subsequent activation of multiple downstream signaling pathways including MAPK, PI3K and TC10 (3,4). These events lead to increased glucose uptake and metabolism, and can promote cell growth. Loss of function mutation or desensitization of the InsR are two major contributors to insulin resistance and Type 2 diabetes (5).
