Uniprot Id

P51452

Target Species

Human

Target Name

DUSP3

Target Full Name

Dual specificity protein phosphatase 3

Target Function

Shows activity both for tyrosine-protein phosphate and serine-protein phosphate, but displays a strong preference toward phosphotyrosines. Specifically dephosphorylates and inactivates ERK1 and ERK2.

Target Subcellular Location

Nucleus.

Target Protein Families

Protein-tyrosine phosphatase family, Non-receptor class dual specificity subfamily

Target Synonyms

Dual specificity phosphatase 3; Dual specificity protein phosphatase 3; Dual specificity protein phosphatase VHR; DUS3_HUMAN; DUSP3; Serine/threonine specific protein phosphatase; Vaccinia H1-related phosphatase; Vaccinia virus phosphatase VH1 related; VHR

Target Background

The protein encoded by this gene is a member of the dual specificity protein phosphatase subfamily. These phosphatases inactivate their target kinases by dephosphorylating both the phosphoserine/threonine and phosphotyrosine residues. They negatively regulate members of the mitogen-activated protein (MAP) kinase superfamily (MAPK/ERK, SAPK/JNK, p38), which are associated with cellular proliferation and differentiation. Different members of the family of dual specificity phosphatases show distinct substrate specificities for various MAP kinases, different tissue distribution and subcellular localization, and different modes of inducibility of their expression by extracellular stimuli. This gene maps in a region that contains the BRCA1 locus which confers susceptibility to breast and ovarian cancer. Although DUSP3 is expressed in both breast and ovarian tissues, mutation screening in breast cancer pedigrees and in sporadic tumors was negative, leading to the conclusion that this gene is not BRCA1.
