Anti-HIVEP zinc finger 1 antibodies are used for the immunodetection of the protein encoded by the HIVEP1 gene. In humans, the canonical protein has a reported length of 2718 amino acid residues and a mass of 296.8 kDa. Its subcellular localization is in the nucleus and cytoplasm. Alternative splicing is reported to yield 3 different isoforms for this protein. It is known to specifically binds to the DNA sequence 5'-GGGACTTTCC-3' which is found in the enhancer elements of numerous viral promoters such as those of SV40, CMV, or HIV-1. Other names for this target antigen include CRYBP1, GAAP, MBP-1, PRDII-BF1, Schnurri-1, ZAS1, ZNF40, and CIRIP. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
