Anti-G Protein-coupled Receptor 111 antibodies enable researchers to detect and measure the G Protein-coupled Receptor 111 antigen in biological samples. This target is a reported synonym of the gene, which encodes . This protein is known to function in GPCR signaling pathways and receptor-mediated signaling pathways, among other biological roles. The human version of G Protein-coupled Receptor 111 has a canonical amino acid length of 708 residues and a protein mass of 78.6 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the membrane of cells. G Protein-coupled Receptor 111 is a member of the G-protein coupled receptor 2 protein family.
