Deficiency of MIP/MTMR14 phosphatase induces a muscle disorder by disrupting Ca2+ homeostasis

Mutations in the MIP phosphatase MTMR14 are associated with human autosomal centronuclear myopathy. Mice that lack MIP have impaired muscle performance and enhanced fatigue due to the accumulation of MIP substrates PtdIns(3,5)P2 and PtdIns(3,4)P2, which cause alterations in intracellular Ca2+ levels...
