Myotubularin

Myotubularin domain represents a region within eukaryotic myotubularin-related proteins that is sometimes found with the GRAM domain InterPro: IPR004182. Myotubularin is a dual-specific lipid phosphatase that dephosphorylates phosphatidylinositol 3-phosphate and phosphatidylinositol (3,5)-bi-phosphate.[2] Mutations in gene encoding myotubularin-related proteins have been associated with disease.[3]
