A number of ELISA Kits are available that target HPTTG, an alias of the protein, PTTG1 regulator of sister chromatid separation, securin. The human protein, encoded by the gene PTTG1, is a member of the Securin family. The protein's cellular localization is indicated to be cytoplasmic and nuclear. Additional synonyms or past names for this protein may include: EAP1, HPTTG, PTTG, TUTR1. Homology is conserved in other species, such as Mouse, Rat, Yeast.
