Anti-RFVT1 antibodies enable researchers to detect and measure the RFVT1 antigen in biological samples. This target is a reported synonym of the SLC52A1 gene, which encodes solute carrier family 52 member 1. This protein is known to function in metabolic processes, among other biological roles. The human version of RFVT1 has a canonical amino acid length of 448 residues and a protein mass of 46.3 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane of cells. Other names for this target antigen include GPCR42, GPR172B, and PAR2.
