Anti-G Protein-coupled Receptor 125 antibodies enable researchers to detect and measure the G Protein-coupled Receptor 125 antigen in biological samples. This target is a reported synonym of the ADGRA3 gene, which encodes adhesion G protein-coupled receptor A3. This protein is known to function in receptor-mediated signaling pathways and GPCR signaling pathways, among other biological roles. The human version of G Protein-coupled Receptor 125 has a canonical amino acid length of 1321 residues and a protein mass of 146.2 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the membrane of cells. This target antigen may also be known as G-protein coupled receptor 125.
