ncbi summary :
This gene encodes a dual-specificity phosphatase that acts on both phosphotyrosine and phosphoserine. It is required for muscle cell differentiation and mutations in this gene have been identified as being responsible for X-linked myotubular myopathy. [provided by RefSeq, Jul 2008]
uniprot summary :
MTM1: Lipid phosphatase which dephosphorylates phosphatidylinositol 3-monophosphate (PI3P) and phosphatidylinositol 3,5-bisphosphate (PI(3,5)P2). Has also been shown to dephosphorylate phosphotyrosine- and phosphoserine- containing peptides. Negatively regulates EGFR degradation through regulation of EGFR trafficking from the late endosome to the lysosome. Plays a role in vacuolar formation and morphology. Regulates desmin intermediate filament assembly and architecture. Plays a role in mitochondrial morphology and positioning. Required for skeletal muscle maintenance but not for myogenesis. Defects in MTM1 are the cause of centronuclear myopathy X-linked (CNMX). A congenital muscle disorder characterized by progressive muscular. weakness and wasting involving mainly limb girdle, trunk, and neck muscles. It may also affect distal muscles. Weakness may be present during childhood or adolescence or may not become evident until the third decade of life. Ptosis is a frequent clinical feature. The most prominent histopathologic features include high frequency of centrally located nuclei in muscle fibers not secondary to regeneration, radial arrangement of sarcoplasmic strands around the central nuclei, and predominance and hypotrophy of type 1 fibers. Belongs to the protein-tyrosine phosphatase family. Non-receptor class myotubularin subfamily. Protein type: Motility/polarity/chemotaxis; EC 3.1.3.64; EC 3.1.3.95; Protein phosphatase, dual-specificity. Chromosomal Location of Human Ortholog: Xq28. Cellular Component: ruffle; I band; late endosome; cytoplasm; plasma membrane; cytosol; filopodium.
