This family represents the phosphatase domain within eukaryotic myotubularin-related proteins. Myotubularin is a dual-specific lipid phosphatase that dephosphorylates phosphatidylinositol 3-phosphate and phosphatidylinositol (3,5)-bi-phosphate [1]. Mutations in gene encoding myotubularin-related proteins have been associated with disease [2].	Domain
