Anti-kid1 antibodies enable researchers to detect and measure the kid1 antigen in biological samples. This target is a reported synonym of the ZNF354A gene, which encodes zinc finger protein 354A. This protein is known to function in the regulation of transcription, among other biological roles. The human version of kid1 has a canonical amino acid length of 605 residues and a protein mass of 69.2 kilodaltons. It is reported to be localized in the nucleus of cells and notably expressed in many tissues, such as the cerebral cortex and stomach. Other names for this target antigen include EZNF, HEL104, and HKL1.
