This entry describes the GAIN subdomain A primarily found in adhesion G protein-coupled receptors L2-4 (AGRL2-4). It is also found in Latrophilin/CIRL, CELR1, AGRB1-3 and related G-protein -coupled receptors (GPCR). The GAIN domain consists of an N-terminal HormR-like domain (IPR053984), followed by the GAIN domain which consists of a stalk (consisting of subdomains A and B) and a GPS motif (IPR000203), followed by a C-terminal transmembrane region (IPR000832) [1].
