DUSP3 Antibody – Mouse Monoclonal

DUSP3: 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. DUSP3 inactivates the mitogen-activated kinases Erk2 and Jnk and is phosphorylated by ZAP-70. Phosphorylation by ZAP-70 is required for DUSP3 to inhibit the Erk2-Elk-1 pathway.
