Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0000881
UniProt IDQ16829
Primary gene name(s)DUSP7
Synonym gene name(s)PYST2
Protein nameDual specificity protein phosphatase 7
Protein functionRegulates the activity of the MAP kinase family in response to changes in the cellular environment. PYST2-S may act as a negative regulator of PYST2-L although it is unclear whether this is by competing for transcription, translation or activation factors. {ECO:0000269|PubMed:14603440}.
