Anti-CHIFB antibodies enable researchers to detect and measure the CHIFB antigen in biological samples. This target is a reported synonym of the DBF4B gene, which encodes DBF4 zinc finger B. This protein is known to function in the cell cycle and the regulation of cell proliferation, among other biological roles. The human version of CHIFB has a canonical amino acid length of 615 residues and a protein mass of 67.2 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types.
