Scientific Data

Western Blot Detection of Human GPR115 antibody by Western Blot. View Larger

Detection of Human GPR115 by Western Blot. Western blot shows lysates of human peripheral blood mononuclear cells (PBMC). PVDF Membrane was probed with 2 µg/mL of Mouse Anti-Human GPR115 Monoclonal Antibody (Catalog # MAB5437) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for GPR115 at approximately 90 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: GPR115

GPR115 is a member of the LN-7TM family of adhesion-type 7-transmembrane (TM) G-protein coupled receptors (GPCR) that show a long extracellular N-terminus (1, 2). The 695 amino acid (aa) human GPR115 sequence predicts a 21 aa signal sequence, a 385 aa N‑terminal extracellular domain (ECD), seven TM regions separated by 6‑24 aa intracellular and extracellular regions, and a 40 aa cytoplasmic tail. Like other LN-7TM members, the ECD contains a highly glycosylated mucin‑like stalk that is predicted to function in adhesion. This is followed by a cysteine-rich GPCR proteolytic cleavage site (GPS) (1). GPS domains, which have been described in other 7TM proteins including ETL, GPR126, HE6, and Latrophilin-1, are cleavage sites for processing proteins into two subunits (3‑7). Within the N‑terminal region that ends with the predicted cleavage site (aa 22‑347), human GPR115 shares 58% aa sequence identity with the corresponding region of mouse and rat GPR115. GPR115 was identified from expressed sequence tags (ESTs) found in pregnant uterus, breast, and the genitourinary tract (1).
