Function

Dual specificity phosphatase or Dual specificity protein phosphatase (DUSP) is a phosphatase which dephosphorylates phosphotyrosine, phosphoserine or phosphothreonine residues^[1]. There are several DUSP enzymes in mammals sharing a common catalytic mechanism. The DUSP include:
• Slingshot phosphatase^[2]
• Phosphatase of regenerating liver (PRL)^[3]
• Cdc14 leads to mitotic exit by dephosphorylation of targets of the protein kinase Cdk1.^[4]
• Cdc25 activates Cdk1 by its dephosphorylation.^[5]
• PTEN (Phosphatase and TEnsin homolog) dephosphorylates phosphasitide substrates.^[6] For details see PTEN.
• Myotubularin dephosphorylates phosphadinylinositol 3-phosphate and phosphadinylinositol (3,5)-bi-phosphate^[7]
• MAPK phosphatase see MAP kinase phosphatase

Relevance

Cdc25A and Cdc25B are overexpressed in several types of cancers and their inhibitors are being tested as chemotherapeutic agents.
PTEN gene is mutated with high frequency in a variety of human cancers.^[8]
Phosphatase of regenerating liver is overexpressed in several types of cancers.

Disease

Myotubularin mutations are responsible for the hereditary motor disease Charcot-Marie-Tooth disease.^[9]
