PTPMT1 (NM_001143984) Human Recombinant Protein

Lipid phosphatase which dephosphorylates phosphatidylglycerophosphate (PGP) to phosphatidylglycerol (PG) (By similarity) . 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 (By similarity) . Has probably a preference for proteins phosphorylated on Ser and/or Thr residues compared to proteins phosphorylated on Tyr residues (By similarity) . Probably involved in regulation of insulin secretion in pancreatic beta cells (By similarity) . May prevent intrinsic apoptosis, probably by regulating mitochondrial membrane integrity (PubMed:24709986) .[UniProtKB/Swiss-Prot Function]
