General description

Myotubularin is a cytoplasmic phosphatase which belongs to the protein-tyrosine phosphatase family. It contains a GRAM domain and a myotubularin phosphatase domain. Myotubularin targets phosphoinositide substrates, including phosphatidylinositol 3-monophosphate (PI3P) and phosphatidylinositol 3,5-bisphosphate (PI(3,5)P2). It may also dephosphorylate phosphotyrosine- and phosphoserine-containing peptides. Myotubularin indirectly regulates many cellular processes that are facilitated by phosphoinositides, and plays an important role in the formation and morphology of membrane-bound intracellular structures such as vacuoles and mitochondria. It also regulates the transport of EGFR from late endosomes to lysosomes, resulting in the degradation of EGFR. Defects in myotubularin result in X-linked myotubular myopathy, a congenital muscle-wasting condition that affects the limb girdle, trunk, and neck muscles. It has also been implicated in other neuromuscular diseases, such as Charcot-Marie-Tooth disease type 4B.

Myotubularin, the phosphatase mutated in X-linked myotubular myopathy, was shown to dephosphorylate phosphatidylinositol 3-monophosphate (PtdIns3P) and was also reported to interact with nuclear transcriptional regulators from the trithorax family. We have characterized a panel of specific antibodies and investigated the

The myotubularin-related 1 (MTMR1) gene belongs to a highly conserved family of eucaryotic phosphatases, with at least 11 members in humans. The founder member of this gene family, MTM1, is mutated in X-linked myotubular myopathy, a severe congenital disorder that
