Description

General description

Dual specificity protein phosphatase 6 (EC 3.1.3.16; EC 3.1.3.48; UniProt Q16828; also known as Dual specificity protein phosphatase PYST1, MAP kinase phosphatase 3, Mitogen-activated protein kinase phosphatase 3, MKP-3) is encoded by the DUSP6 (also known as HH19, MKP3, PYST1) gene (Gene ID 1848) in human. MPK-3 (DUSP6) belongs to the family of dual-specificity phosphatases (DUSPs) that mediate dephosphorylation of MAPKs on threonine/serine and tyrosine residues. DUSP6 is upregulated in HER2+ carcinomas and is among several DUSPs thought to be involved in breast cancer metastasis. DUSP1, DUSP4, and DUSP6 are induced during epithelial-to-mesenchymal transition (EMT) and are involved in forming and maintaining breast cancer stem cells (CSCs), DUSP1 knockdown reduces CSC formation, while DUSP4 or DUSP6 knockdown enhances CSC formation. PKC CK2alpha is reported to phosphorylate DUSP6 and increase its dephosphatase activity. ERK1/2, on the other hand, can phosphorylate DUSP6 to promote its proteosomal degradation.
