Anti-ZAN75 antibodies are protein reagents that detect specific antigens. The ZAN75 antigen is another term for the human protein zinc finger protein 326, encoded by the ZNF326 gene. The protein is an important component of the DBIRD complex, a multiprotein complex that acts at the interface between core mRNP particles and RNA polymerase II (RNAPII) and integrates transcript elongation with the regulation of alternative splicing: the DBIRD complex affects local transcript elongation rates and alternative splicing of a large set of exons embedded in (A + T)-rich DNA regions. Canonically, it has an amino acid length of 582 residues and a mass of 65.7 kilodaltons. Its subcellular localization is in the nucleus and it is widely expressed in many tissue types. The ZAN75 protein is a member of the AKAP95 protein family.
