Anti-TPTE antibodies are used in the immunodetection of the protein transmembrane phosphatase with tensin homology. In humans, the canonical protein has a reported length of 551 amino acid residues and a mass of 64.3 kDa. Its subcellular localization is in the membrane. Up to 4 different isoforms have been reported for this protein. It is notably expressed in the testis. TPTE is suspected to be involved in in signal transduction. Synonyms for this target antigen include PTEN2, putative tyrosine-protein phosphatase TPTE, PTEN-related tyrosine phosphatase, cancer/testis antigen 44, tensin, putative protein-tyrosine phosphatase, and CT44. Some TPTE antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
