Anti-PRAF1 antibodies enable researchers to detect and measure the PRAF1 antigen in biological samples. This target is a reported synonym of the RABAC1 gene, which encodes Rab acceptor 1. The human version of PRAF1 has a canonical amino acid length of 185 residues and a protein mass of 20.6 kilodaltons. It is reported to be localized in the cell membrane, cytoplasmic vesicles, Golgi, and cytoplasm of cells and widely expressed in many tissue types. PRAF1 is a member of the PRA1 protein family.
