Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Dual specificity protein phosphatase 7 is an enzyme that in humans is encoded by the DUSP7 gene.Dual-specificity phosphatases (DUSPs) constitute a large heterogeneous subgroup of the type I cysteine-based protein-tyrosine phosphatase superfamily. DUSPs are characterized by their ability to de-phosphorylate both tyrosine (EC 3.1.3.48) and serine / threonine (EC 3.1.3.16) residues. DUSP7 belongs to a class of DUSPs, designated MKPs, that dephosphorylate MAPK (mitogen-activated protein kinase) proteins ERK, JNK, and p38 with specificity distinct from that of individual MKP proteins. MKPs contain a highly conserved C-terminal catalytic domain and an N-terminal Cdc25-like (CH2) domain. MAPK activation cascades mediate various physiologic processes, including cellular proliferation, apoptosis, differentiation, and stress responses.
