Anti-ZAPHIR antibodies enable researchers to detect and measure the ZAPHIR antigen in biological samples. This target is a reported synonym of the ZNF419 gene, which encodes zinc finger protein 419. This protein is known to function in the regulation of transcription, among other biological roles. The human version of ZAPHIR has a canonical amino acid length of 510 residues and a protein mass of 58.6 kilodaltons, although 6 isoforms have been identified. It is reported to be localized in the nucleus of cells. ZAPHIR is a member of the Krueppel C2H2-type zinc-finger protein family.
