Dual-specific phosphatase-6 (DUSP6), also known as mitogen-activated protein kinase phosphatase-3 (MKP3), has been characterized as a negative feedback regulator of ERK1/2 signaling. It serves a specific and conserved function on the dephosphorylation of extracellular signal-regulated kinase 1/2 (ERK1/2). DUSP6 is a cytoplasmic DUSP known to catalyze the removal of phosphate groups from threonine and tyrosine residues on Erk1/2, Which belongs to a family of 25 protein phosphatases that dephosphorylate phosphotyrosine and phosphoserine/phosphothreonine residues within the same substrate.
