|Function||Dual specificity protein phosphatase (PubMed:9788880). Shows high activity towards MAPK1/ERK2 (PubMed:9788880). Also has lower activity towards MAPK14 and MAPK8 (PubMed:9788880). In arrested oocytes, plays a role in meiotic resumption (By similarity). Promotes nuclear envelope breakdown and activation of the CDK1/Cyclin-B complex in oocytes, probably by dephosphorylating and inactivating the conventional protein kinase C (cPKC) isozyme PRKCB (By similarity). May also inactivate PRKCA and/or PRKCG (By similarity). Also important in oocytes for normal chromosome alignment on the metaphase plate and progression to anaphase, where it might regulate activity of the spindle-assembly checkpoint (SAC) complex (By similarity).|
|Tissue Location||Strongly expressed in liver (PubMed:8670865). Expressed at significantly higher levels in malignant hematopoietic cells than in corresponding non-malignant cells (PubMed:14576828).|

Dual-specificity phosphatases (DUSPs) constitute a largeheterogeneous subgroup of the type I cysteine-basedprotein-tyrosine phosphatase superfamily. DUSPs are characterizedby their ability to dephosphorylate both tyrosine andserine/threonine residues. DUSP7 belongs to a class of DUSPs,designated MKPs, that dephosphorylate MAPK (mitogen-activatedprotein kinase) proteins ERK (see MIM 601795), JNK (see MIM601158), and p38 (see MIM 600289) with specificity distinct fromthat of individual MKP proteins. MKPs contain a highly conservedC-terminal catalytic domain and an N-terminal Cdc25 (see MIM116947)-like (CH2) domain. MAPK activation cascades mediate variousphysiologic processes, including cellular proliferation, apoptosis,differentiation, and stress responses (summary by Patterson et al.,2009 [PubMed 19228121]).
