Mitogen-activated protein kinase (MAPK) phosphatases are dual-specificity phosphatases (DUSPs) that dephosphorylate phosphothreonine and phosphotyrosine residues within MAPKs. DUSP6 preferentially dephosphorylates extracellular signal-regulated kinases 1 and 2 (ERK1/2) rendering them inactive. Here, we study the role of DUSP6 in CD4(+) T-cell
