The Insulin/Relaxin structural family of proteins consists of at least seven members, each containing an insulin-like heterodimeric structure of two polypeptide chains held together by two inter-chain disulfide bonds. The INSL5/INSL7 hybrid contains the β-chain of INSL7 (Relaxin-3), linked to the α-chain of INSL5. The INSL5/INSL7 hybrid protein can specifically activate the G protein-coupled receptors, GPCR135 and GPCR142, but unlike Relaxin-3, does not induce significant activation of the LGR7 receptor. Recombinant Human INSL5/INSL7 hybrid is a heterodimeric, 5.2 kDa protein consisting of a 27 amino acid β-chain linked to a 21 amino acid α-chain by two disulfide bonds.
