Protein

Phosphatidylglycerophosphatase and protein-tyrosine phosphatase 1

Gene

PTPMT1

Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein 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. 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 (By similarity).By similarity

Catalytic activityi

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