Gene: MTM1 (myotubularin 1) Homo sapiens
Symbol: MTM1
Name: myotubularin 1
Description: Exhibits intermediate filament binding activity; phosphatase activity; and phosphatidylinositol binding activity. Involved in several processes, including dephosphorylation; intermediate filament organization; and mitochondrion morphogenesis. Localizes to several cellular components, including the filopodium; late endosome; and ruffle. Implicated in centronuclear myopathy X-linked and congenital structural myopathy.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: CNM; MTMX; myotubularin; phosphatidylinositol-3,5-bisphosphate 3-phosphatase; phosphatidylinositol-3-phosphate phosphatase; XLMTM
