Myotubularin-related protein 1 (MTMR1)

Lipid phosphatase that has high specificity for phosphatidylinositol 3-phosphate and has no action with phosphatidylinositol 4-phosphate, phosphatidylinositol (4,5)- bisphosphate and phosphatidylinositol (3,4,5)-trisphosphate (PubMed:11733541, PubMed:27018598). Activity with phosphatidylinositol (3,5)-bisphosphate is controversial; it has been proven by PubMed:27018598, while PubMed:11733541 find no activity with this substrate.
