DUSP1 a non-receptor, dual-specificity phosphoprotein phosphatase (DUSP). Different members of the DUSP family show distinct substrate specificities for MAPKs, different tissue distribution and subcellular localization, and different modes of inducibility of their expression by extracellular stimuli. DUSP1 specifically inactivates mitogen-activated protein (MAP) kinase in vitro by the concomitant dephosphorylation. It is induced in human skin fibroblasts by oxidative/heat stress and growth factors. Contains 1 rhodanese domain. Note: This description may include information from UniProtKB.
