General description
MTM1 (myotubularin 1) is a lipid phosphatase, which is abundant at the junctional SR (sarcoplasmic reticulum) of the muscle triads. It is a member of conserved phosphatase family myotubularin, which contains both active phosphatases and inactive myotubularin-related proteins (MTMRs).
Immunogen
Myotubularin recombinant protein epitope signature tag (PrEST)
Application
Anti-MTM1 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Biochem/physiol Actions
MTM1 (myotubularin 1) protein plays an essential role in facilitating the curvature of SR (sarcoplasmic reticulum) membrane and SR remodelling. Therefore, it is critical for homeostasis of calcium and excitation-contraction coupling. The major function of this protein is the dephosphorylation of phosphatidylinositol-3-phosphate (PtdIns3P) and phosphatidylinositol-3,5-bisphosphate (PtdIns(3,5P)2). Mutations in this gene are linked to X-linked myotubular myopathy (XLMTM), which is an inherited disorder characterized by severe generalized hypotonia and skeletal muscles weakness with respiratory insufficiency. Mostly this disease is fatal in the initial months of life. Heterozygous mutations resulting in abnormal splicing in this gene are associated with early onset, slowly progressive myopathy. c.431delT (p.Leu144fs) mutation in this gene results in bilateral subdural hygromas and cephalhaematomas in male twins suffering from severe myotubular myopathy.
Features and Benefits
Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.
Every Prestige Antibody is tested in the following ways:
Every Prestige Antibody is tested in the following ways:
- IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
- Protein array of 364 human recombinant protein fragments.

X-linked myotubular myopathy (XLMTM) is a congenital disorder caused by mutations of the myotubularin gene, MTM1. Myotubularin belongs to a large family of conserved lipid phosphatases that include both catalytically active and inactive myotubularin-related proteins (i.e., "MTMRs"). Biochemically, catalytically inactive

Centronuclear myopathies (CNMs) are characterized by muscle weakness and increased numbers of central nuclei within myofibers. X-linked myotubular myopathy, the most common severe form of CNM, is caused by mutations in MTM1, encoding myotubularin (MTM1), a lipid phosphatase. To increase
