Phosphatase Subfamily MTMR10

Phosphatase Classification: FoldCC1: Superfamily CC1: Family Myotubularin: Subfamily MTMR10

MTMR10 is a conserved pseudophosphatase in metazoan. Its molecular function is unclear.

Evolution

MTMR10 is found in most metazoan.

Domain Structure

MTMR10 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. Sponge.

Catalytic activity and functions

MTMR10 is an inactive phosphatase (pseudophosphatase), but its function is unclear. Other pseudophosphatases within myotubularin family (Subfamily MTMR5 and Subfamily MTMR9) regulate active myotubularins via protein interactions mediated by coiled coils. It interacts with MTM1 and MTMR1 of MTMR1 subfamily [1].
