Anti-VHLaK antibodies enable researchers to detect and measure the VHLaK antigen in biological samples. This target is a reported synonym of the ZNF197 gene, which encodes zinc finger protein 197. This protein is suspected to be involved in transcriptional regulation. The human version of VHLaK has a canonical amino acid length of 1029 residues and a protein mass of 118.8 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells. Other names for this target antigen include D3S1363E and P18.
