cys-based protein tyrosine phosphatase and dual-specificity phosphatase superfamily; This superfamily is composed of cys-based phosphatases, which includes classical protein tyrosine phosphatases (PTPs) as well as dual-specificity phosphatases (DUSPs or DSPs). They are characterized by a CxxxxxR conserved catalytic loop (where C is the catalytic cysteine, x is any amino acid, and R is an arginine). PTPs are part of the tyrosine phosphorylation/dephosphorylation regulatory mechanism, and are important in the response of the cells to physiologic and pathologic changes in their environment. DUSPs show more substrate diversity (including RNA and lipids) and include pTyr, pSer, and pThr phosphatases.

protein tyrosine phosphatase-like pseudophosphatase domain of myotubularin related phosphoinositide phosphatase 9; Myotubularin related phosphoinositide phosphatase 9 (MTMR9) is enzymatically inactive and contains a C-terminal coiled-coil domain and an N-terminal PH-GRAM domain. Mutations have been associated with obesity and metabolic syndrome. In general, myotubularins are a unique subgroup of protein tyrosine phosphatases that use inositol phospholipids, rather than phosphoproteins, as substrates. MTMR9 is a pseudophosphatase that lacks the catalytic cysteine in its catalytic pocket. It forms complexes with catalytically active MTMR6, MTMR7 and MTMR8, and regulates their activities; the complexes display differential substrate preferences. The MTMR6/R9 complex serves to inhibit stress-induced apoptosis while the MTMR8/R9 complex inhibits autophagy.

Myotubularian (MTM) related 9 protein (MTMR9) Pleckstrin Homology-Glucosyltransferases, Rab-like GTPase activators and Myotubularins (PH-GRAM) domain; MTMR9 is a catalytically inactive phosphatase that plays a role as an adapter for the phosphatase myotubularin to regulate myotubularintracellular location. It contains a Gly residue instead of a conserved Cys residue in the dsPTPase catalytic loop which renders it catalytically inactive as a phosphatase. MTMR9 contains an N-terminal PH-GRAM domain, a Rac-induced recruitment domain (RID) domain, an inactive PTP domain, a SET interaction domain, and a C-terminal coiled-coil region. Myotubularin-related proteins are a subfamily of protein tyrosine phosphatases (PTPs) that dephosphorylate D3-phosphorylated inositol lipids. Mutations in this family cause the human neuromuscular disorders myotubular myopathy and type 4B Charcot-Marie-Tooth syndrome. 6 of the 13 MTMRs (MTMRs 5, 9-13) contain naturally occurring substitutions of residues required for catalysis by PTP family enzymes. Although these proteins are predicted to be enzymatically inactive, they are thought to function as antagonists of endogenous phosphatase activity or interaction modules. Most MTMRs contain a N-terminal PH-GRAM domain, a Rac-induced recruitment domain (RID) domain, a PTP domain (which may be active or inactive), a SET-interaction domain, and a C-terminal coiled-coil region. In addition some members contain DENN domain N-terminal to the PH-GRAM domain and FYVE, PDZ, and PH domains C-terminal to the coiled-coil region. The GRAM domain, found in myotubularins, glucosyltransferases, and other putative membrane-associated proteins, is part of a larger motif with a pleckstrin homology (PH) domain fold. The PH domain family possesses multiple functions including the ability to bind phosphoinositides via its beta1/beta2, beta3/beta4, and beta6/beta7 connecting loops and to other proteins. However, no phosphoinositide binding sites have been found for the MTMRs to date.

protein tyrosine phosphatase-like domain of myotubularin related phosphoinositide phosphatases 6, 7, and 8; This subgroup of enzymatically active phosphatase domains of myotubularins consists of MTMR6, MTMR7 and MTMR8, and related domains. Beside the phosphatase domain, they contain a C-terminal coiled-coil domain and an N-terminal PH-GRAM domain. In general, myotubularins are a unique subgroup of protein tyrosine phosphatases that use inositol phospholipids, rather than phosphoproteins, as substrates. They dephosphorylate the D-3 position of phosphatidylinositol 3-phosphate [PI(3)P] and phosphatidylinositol 3,5-bisphosphate [PI(3,5)P2], generating phosphatidylinositol and phosphatidylinositol 5-phosphate [PI(5)P], respectively. MTMR6, MTMR7 and MTMR8 form complexes with catalytically inactive MTMR9, and display differential substrate preferences. In cells, the MTMR6/R9 complex significantly increases the cellular levels of PtdIns(5)P, the product of PI(3,5)P(2) dephosphorylation, whereas the MTMR8/R9 complex reduces cellular PtdIns(3)P levels. The MTMR6/R9 complex serves to inhibit stress-induced apoptosis while the MTMR8/R9 complex inhibits autophagy.

Mutations in MTM1 cause X-linked myotubular myopathy. In general, myotubularins are a unique subgroup of protein tyrosine phosphatases that use inositol phospholipids, rather than phosphoproteins, as substrates. They dephosphorylate the D-3 position of phosphatidylinositol 3-phosphate [PI(3)P] and phosphatidylinositol 3,5-bisphosphate [PI(3,5)P2], generating phosphatidylinositol and phosphatidylinositol 5-phosphate [PI(5)P], respectively.

protein tyrosine phosphatase-like pseudophosphatase domain of myotubularin related phosphoinositide phosphatases 5 and 13; This subgroup of enzymatically inactive phosphatase domains of myotubularins consists of MTMR5, also known as SET binding factor 1 (SBF1) and MTMR13, also known as SET binding factor 2 (SBF2), and similar domains. Beside the pseudophosphatase domain, they contain a variety of other domains, including a DENN and a PH-like domain. In general, myotubularins are a unique subgroup of protein tyrosine phosphatases that use inositol phospholipids, rather than phosphoproteins, as substrates. MTMR5 and MTMR13 are pseudophosphatases that lack the catalytic cysteine in their catalytic pocket. Mutations in MTMR13 causes Charcot-Marie-Tooth type 4B2, a severe childhood-onset neuromuscular disorder, characterized by demyelination and redundant loops of myelin known as myelin outfoldings, a similar phenotype as mutations in MTMR2. Mutations in the MTMR5 gene cause Charcot-Marie-tooth disease type 4B3. MTMR5 and MTMR13 interact with MTMR2 and stimulate its phosphatase activity.

Myotubularian (MTM) related (MTMR) 7 and 8 proteins Pleckstrin Homology-Glucosyltransferases, Rab-like GTPase activators and Myotubularins (PH-GRAM) domain; MTMR6, MTMR7, and MRMR8 are all member of the myotubularin dual specificity protein phosphatase gene family. They bind to phosphoinositide lipids through its PH-GRAM domain. These proteins also interact with each other as well as MTMR9. They contain a N-terminal PH-GRAM domain, a Rac-induced recruitment domain (RID) domain, an active PTP domain, a SET-interaction domain, and a C-terminal coiled-coil region. Myotubularin-related proteins are a subfamily of protein tyrosine phosphatases (PTPs) that dephosphorylate D3-phosphorylated inositol lipids. Mutations in this family cause the human neuromuscular disorders myotubular myopathy and type 4B Charcot-Marie-Tooth syndrome. 6 of the 13 MTMRs (MTMRs 5, 9-13) contain naturally occurring substitutions of residues required for catalysis by PTP family enzymes. Although these proteins are predicted to be enzymatically inactive, they are thought to function as antagonists of endogenous phosphatase activity or interaction modules. Most MTMRs contain a N-terminal PH-GRAM domain, a Rac-induced recruitment domain (RID) domain, a PTP domain (which may be active or inactive), a SET-interaction domain, and a C-terminal coiled-coil region. In addition some members contain DENN domain N-terminal to the PH-GRAM domain and FYVE, PDZ, and PH domains C-terminal to the coiled-coil region. The lipid-binding FYVE domain has been shown to bind phosphotidylinositol-3-phosphate. The GRAM domain, found in myotubularins, glucosyltransferases, and other putative membrane-associated proteins, is part of a larger motif with a pleckstrin homology (PH) domain fold. The PH domain family possesses multiple functions including the ability to bind phosphoinositides via its beta1/beta2, beta3/beta4, and beta6/beta7 connecting loops and to other proteins. However, no phosphoinositide binding sites have been found for the MTMRs to date.
