Anti-DUSP1 antibodies are used in the immunodetection of the protein dual specificity phosphatase 1. In humans, the canonical protein has a reported length of 367 amino acid residues and a mass of 39.3 kDa. Its subcellular localization is in the nucleus. It is notably expressed at high levels in the lung, liver placenta and pancreas. A member of the Protein-tyrosine phosphatase protein family, DUSP1 is known to be involved with the cell cycle and the regulation of cell proliferation. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include HVH1, MKP-1, MKP1, PTPN10, dual specificity protein phosphatase 1, CL 100, MAP kinase phosphatase 1, and CL100. DUSP1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species.
