Anti-ERP1 antibodies enable researchers to detect and measure the ERP1 antigen in biological samples. This target is a reported synonym of the ZNF471 gene, which encodes zinc finger protein 471. This protein is known to function in the regulation of transcription, among other biological roles. The human version of ERP1 has a canonical amino acid length of 626 residues and a protein mass of 73 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells. ERP1 is a member of the Krueppel C2H2-type zinc-finger protein family.
