UniProt Protein Function: | MTMR7: a protein of the myotubularin family. Myotubularins are a family of unique protein tyrosine phosphatases that utilize inositol phospholipids, rather than phosphoproteins, as physiological substrates. Myotubularins specifically dephosphorylate phosphatidylinositol 3-phosphate [PI(3)P] and phosphatidylinositol 3,5-bisphosphate [PI(3,5)P2], generating phosphatidylinositol and phosphatidylinositol 5-phosphate [PI(5)P], respectively. PI(3)P and PI(3,5)P2 regulate membrane trafficking events through the recruitment of effector proteins containing the lipid-binding domains FYVE, PH, and ENTH. MTMR5, -9, -10, -11, -12, -13 are catalytically inactive lipid phosphatases but may mediate important protein-protein interactions. Expressed at high levels in the brain. Two alternatively spliced human isoforms have been described.Protein type: Protein phosphatase, tyrosine (non-receptor); Motility/polarity/chemotaxis; EC 3.1.3.-; Phosphatase, lipidChromosomal Location of Human Ortholog: 8p22Cellular Component: membrane; cytosolMolecular Function: protein tyrosine phosphatase activityBiological Process: phospholipid metabolic process; inositol phosphate dephosphorylation; phosphatidylinositol biosynthetic process; phosphoinositide dephosphorylation; protein amino acid dephosphorylation |

NCBI Summary: | This gene encodes a member of the myotubularin family of tyrosine/dual-specificity phosphatases. The encoded protein is characterized by four distinct domains that are conserved among all members of the myotubularin family: the glucosyltransferase, Rab-like GTPase activator and myotubularins domain, the Rac-induced recruitment domain, the protein tyrosine phosphatases and dual-specificity phosphatases domain and the suppressor of variegation 3-9, enhancer-of-zeste, and trithorax interaction domain. This protein dephosphorylates the target substrates phosphatidylinositol 3-phosphate and inositol 1,3-bisphosphate. A pseudogene of this gene is found on chromosome 5.
