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. DUSP4 inactivates ERK1, ERK2 and JNK, is expressed in a variety of tissues, and is localized in the nucleus. Induced by hepatocyte growth factor (HGF) and vascular endothelial cell growth factor (VEGF) in human endothelial cells. Two alternatively spliced isoforms have been described. In addition, multiple polyadenylation sites have been reported. Contains 1 rhodanese domain. Note: This description may include information from UniProtKB.
