Description

Antigen: synthetic peptide from human GPR40 amino acids 210-222 · Host: rabbit · Application(s): IHC; other applications not tested · GPR40 is a seven transmembrane G Protein-coupled receptor with signalling mediated by medium- and long-chain fatty acids.1,2 Found predominantly in the β-cells of pancreatic islets, it has been implicated in the regulation of insulin secretion.3,4 Overexpression of GPR40 in mouse β cells leads to glucose intolerance suggesting a link between GPR40 expression and diabetes.3,4 The receptor has also been identified as a possible mediator of oleate- and linoleate- stimulated proliferation of the human breast cancer cell line, MCF-7.5,6 GPR40 has a calculated mass of 31.4 kDa bases on its amino acid sequence.
