A number of ELISA Kits are available that target Zas3, an alias of the protein, human immunodeficiency virus type I enhancer binding protein 3. The human protein is encoded by the gene HIVEP3. The protein's cellular localization is indicated to be cytoplasmic and nuclear. Additional synonyms or past names for this protein may include: KBP-1, KBP1, KRC, SHN3, Schnurri-3, ZAS3, ZNF40C. Homology is conserved in other species, such as Mouse, Rat, Frog.
