Anti-ZASC1 antibodies enable researchers to detect and measure the ZASC1 antigen in biological samples. This target is a reported synonym of the ZNF639 gene, which encodes zinc finger protein 639. This protein is known to function in the regulation of transcription, among other biological roles. The human version of ZASC1 has a canonical amino acid length of 485 residues and a protein mass of 56.1 kilodaltons. It is reported to be localized in the nucleus of cells. Other names for this target antigen include ANC-2H01 and ANC_2H01.
