Anti-PTP4A1 antibodies are used in the immunodetection of the protein protein tyrosine phosphatase 4A1. In humans, the canonical protein has a reported length of 173 amino acid residues and a mass of 19.8 kDa. Its subcellular localization is in the cell membrane, nucleus, ER, and cytoplasm. It is reported to be expressed in bone marrow, lymph nodes, T lymphocytes, spleen, thymus and tonsil. A member of the Protein-tyrosine phosphatase protein family, PTP4A1 is known to be involved with the cell cycle and protein dephosphorylation. Synonyms for this target antigen include PRL-1, PRL1, PTP(CAAX1), PTPCAAX1, protein tyrosine phosphatase type IVA 1, and HH72. PTP4A1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of PTP4A1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
