Protein

Phosphatidylglycerophosphatase and protein-tyrosine phosphatase 1

Gene
Ptpmt1
Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at transcript leveli

Functioni

Lipid phosphatase which dephosphorylates phosphatidylglycerophosphate (PGP) to phosphatidylglycerol (PG). PGP is an essential intermediate in the biosynthetic pathway of cardiolipin, a mitochondrial-specific phospholipid regulating the membrane integrity and activities of the organelle By similarity. Has also been shown to display phosphatase activity toward phosphoprotein substrates, specifically mediates dephosphorylation of mitochondrial proteins, thereby playing an essential role in ATP production. Has probably a preference for proteins phosphorylated on Ser and/or Thr residues compared to proteins phosphorylated on Tyr residues. Probably involved in regulation of insulin secretion in pancreatic beta cells.1 Publication

Catalytic activityi

Protein tyrosine phosphate + H2O = protein tyrosine + phosphate.
[a protein]-serine/threonine phosphate + H2O = [a protein]-serine/threonine + phosphate.
Phosphatidylglycerophosphate + H2O = phosphatidylglycerol + phosphate.

Miscellaneous

Its absence in pancreatic insulinoma cell line INS-1 832/13 alters the mitochondrial phosphoprotein profile and markedly enhances both ATP production and insulin secretion, suggesting that it may serve as a drug target for the treatment of type II diabetes.
