Anti-Jdp1 antibodies enable researchers to detect and measure the Jdp1 antigen in biological samples. This target is a reported synonym of the BATF3 gene, which encodes basic leucine zipper ATF-like transcription factor 3. This protein is known to function in the differentiation of certain cell types, among other biological roles. The human version of Jdp1 has a canonical amino acid length of 127 residues and a protein mass of 14.5 kilodaltons. It is reported to be localized in the nucleus of cells. Jdp1 is a member of the BZIP protein family.
