Anti-ERRF antibodies enable researchers to detect and measure the ERRF antigen in biological samples. This target is a reported synonym of the SRARP gene, which encodes steroid receptor associated and regulated protein. This protein is believed to regulate the transcriptional function of androgen and estrogen receptors. The human version of ERRF has a canonical amino acid length of 169 residues and a protein mass of 17.7 kilodaltons.
