DUSP5 Inhibitors

Dual specificity phosphatases (DUSPs) are a subclass of the protein tyrosine phosphatase (PTP) gene superfamily, which are selective for dephosphorylating critical phosphothreonine and phosphotyrosine residues within MAP kinases. Biochemicals that inhibit DUSP5 have many applications in biochemical and physiological research.

NSC-95397 acts as an inhibitor of DUSPs by binding to its active site. By doing so, it disrupts the enzyme′s ability to dephosphorylate its substrate proteins, including critical signaling molecules like ERK and JNK. This interference results in prolonged phosphorylation and activation of downstream signaling pathways.
