Anti-HIVEP zinc finger 3 antibodies are used for the immunodetection of the protein encoded by the HIVEP3 gene. In humans, the canonical protein has a reported length of 2406 amino acid residues and a mass of 259.5 kDa. Its subcellular localization is in the nucleus and cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. It is reported to play a role in of transcription factor; binds to recognition signal sequences (Rss heptamer) for somatic recombination of immunoglobulin and T-cell receptor gene segments; Binds also to the kappa-B motif of gene such as S100A4, involved in cell progression and differentiation. Post-translational modifications have been described, including phosphorylation. Other names for this target antigen include ZAS family, member 3, human immunodeficiency virus type I enhancer binding protein 3, kappa-B and V(D)J recombination signal sequences-binding protein, and transcription factor HIVEP3. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species.
