Myotubularian (MTM) related 4 protein (MTMR4) Pleckstrin Homology-Glucosyltransferases, Rab-like GTPase activators and Myotubularins (PH-GRAM) domain; MTMR4 is a member of the myotubularin dual specificity protein phosphatase gene family. MTMR4 binds to phosphoinositide lipids through its PH-GRAM domain, and can hydrolyze phosphatidylinositol(3)-phosphate and phosphatidylinositol(3,5)-biphosphate in vitro. The protein form heteromers with MTMR3. Both MTMR3 and MTMR4 contain a N-terminal PH-GRAM domain, a Rac-induced recruitment domain (RID) domain, an active PTP domain, a SET-interaction domain, a coiled-coil region, and a C-terminal lipid-binding FYVE domain which binds phosphotidylinositol-3-phosphate. 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. Pssm-ID: 270150 Cd Length: 114 Bit Score: 249.51 E-value: 2.17e-78

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.

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. Pssm-ID: 350384 Cd Length: 224 Bit Score: 174.45 E-value: 1.69e-49

Myotubularian (MTM) related 3 protein (MTMR3) Pleckstrin Homology-Glucosyltransferases, Rab-like GTPase activators and Myotubularins (PH-GRAM) domain; MTMR3 is a member of the myotubularin dual specificity protein phosphatase gene family. MTMR3 binds to phosphoinositide lipids through its PH-GRAM domain, and can hydrolyze phosphatidylinositol(3)-phosphate and phosphatidylinositol(3,5)-biphosphate in vitro. The protein can self-associate and also form heteromers with MTMR4. Both MTMR3 and MTMR4 contain a N-terminal PH-GRAM domain, a Rac-induced recruitment domain (RID) domain, an active PTP domain, a SET-interaction domain, a coiled-coil region, and a C-terminal lipid-binding FYVE domain which binds phosphotidylinositol-3-phosphate. 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. Pssm-ID: 270149 Cd Length: 94 Bit Score: 163.25 E-value: 2.60e-47
