CC -!- FUNCTION: Acts as an adapter for the myotubularin-related phosphatases.
CC Regulates phosphatase MTM1 protein stability and possibly its
CC intracellular location. By stabilizing MTM1 protein levels, required
CC for skeletal muscle maintenance but not for myogenesis.
CC {ECO:0000250|UniProtKB:Q80TA6}.
CC -!- SUBUNIT: Heterodimer with lipid phosphatase MTM1 (By similarity).
CC Heterodimer with lipid phosphatase MTMR2 (By similarity).
CC {ECO:0000250|UniProtKB:Q80TA6, ECO:0000250|UniProtKB:Q9C0I1}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q9C0I1}.
CC Sarcoplasmic reticulum {ECO:0000250|UniProtKB:Q80TA6}. Cytoplasm,
CC myofibril, sarcomere {ECO:0000250|UniProtKB:Q80TA6}. Note=Localizes to
CC punctate vesicles when associated with MTM1 (By similarity). Localizes
CC to triads, a structure formed by a T tubule and two sarcoplasmic
CC reticulum terminal cisterna. In skeletal muscles, co-localizes with
CC MTM1 in the sarcomere. Partially localizes to the sarcoplasmic
CC reticulum in skeletal muscles (By similarity).
CC {ECO:0000250|UniProtKB:Q80TA6, ECO:0000250|UniProtKB:Q9C0I1}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=Q5FVM6-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q5FVM6-2; Sequence=VSP_030724, VSP_030725;
CC -!- SIMILARITY: Belongs to the protein-tyrosine phosphatase family. Non-
CC receptor class myotubularin subfamily. {ECO:0000305}.
CC -!- CAUTION: Although it belongs to the non-receptor class myotubularin
CC subfamily, lacks the conserved active site cysteine residue at position
CC 392 in the dsPTPase catalytic loop and does not have phosphatase
CC activity. {ECO:0000250|UniProtKB:Q9C0I1}.
