Anti-ZNF-X antibodies enable researchers to detect and measure the ZNF-X antigen in biological samples. This target is a reported synonym of the ZBTB43 gene, which encodes zinc finger and BTB domain containing 43. This protein is known to function in the regulation of transcription, among other biological roles. The human version of ZNF-X has a canonical amino acid length of 467 residues and a protein mass of 52.6 kilodaltons. It is reported to be localized in the nucleus of cells and notably expressed in many tissues, such as the adrenal gland, tonsil, and adipose tissue. Other names for this target antigen include ZBTB22B and ZNF297B.
