Phosphatase Classification: Fold CC1: Superfamily CC1: Family Myotubularin: Subfamily YMR1
YMR1 encodes PI(3)P phosphatase found in fungi [1]. It is the single myotubularin in most fungi.
Evolution
YMR1 is found in most fungi.
Domain Structure
YMR1 subfamily has three domains: PH/GRAM, phosphatase domain and coiled-coil domain. The GRAM domain is similar to PH domain in structure and is found in membrane-associated proteins.
Catalytic activity and functions
YMR1 of budding yeast encodes PI(3)P phosphatase, so does its ortholog in fission yeast [1, 2].
