Anti-GRAL antibodies enable researchers to detect and measure the GRAL antigen in biological samples. This target is a reported synonym of the GFRAL gene, which encodes GDNF family receptor alpha like. This protein is known to function in the regulation of apoptosis and nervous system development, among other biological roles. The human version of GRAL has a canonical amino acid length of 394 residues and a protein mass of 44.5 kilodaltons. It is reported to be localized in the cell membrane of cells. GRAL is a member of the GDNFR protein family.
