Anti-MRGD antibodies enable researchers to detect and measure the MRGD antigen in biological samples. This target is a reported synonym of the MRGPRD gene, which encodes MAS related GPR family member D. This protein is known to function in GPCR signaling pathways, among other biological roles. The human version of MRGD has a canonical amino acid length of 321 residues and a protein mass of 36.1 kilodaltons. It is reported to be localized in the cell membrane of cells. MRGD is a member of the G-protein coupled receptor 1 protein family.
