Anti-SENP1 antibodies are used in the immunodetection of the protein SUMO specific peptidase 1. In humans, the canonical protein has a reported length of 644 amino acid residues and a mass of 73.5 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is reported to be highly expressed in the testis. A member of the Peptidase C48 protein family, SENP1 is a reported protease that catalyzes two essential functions in the SUMO pathway. Synonyms for this target antigen include sentrin-specific protease 1, SUMO1/sentrin specific peptidase 1, SUMO1/sentrin specific protease 1, sentrin/SUMO-specific protease SENP1, and SuPr-2. SENP1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Over 70 citations in the literature describe the use of SENP1 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
