 140-233 4.08e-56

GRAM domain-containing protein (GRAMDC) Pleckstrin Homology-Glucosyltransferases, Rab-like GTPase activators and Myotubularins (PH-GRAM) domain; The GRAMDC proteins are membrane proteins. Nothing is known about its function. Members include: GRAMDC1A, GRAMDC1B, GRAMDC1C, GRAMDC2, GRAMDC3, GRAMDC4, and GRAMDC-like proteins. All of the members, except for GRAMDC4 are included in this hierarchy. Each contains a single PH-GRAM domain at their N-terminus. The GRAM domain is found in glucosyltransferases, myotubularins and other putative membrane-associated proteins. The GRAM domain is part of a larger motif with a pleckstrin homology (PH) domain fold.

 410-556 7.40e-49

VAD1 Analog of StAR-related lipid transfer domain; The VASt (VAD1 Analog of StAR-related lipid transfer) domain is conserved across eukaryotes and is structurally related to Bet v1-like domains, including START lipid-binding domains. The 190-amino acid VASt domain is predominantly associated with lipid binding domains such as GRAM pfam02893, C2 and PH domains. The VASt domain is likely to have a function in binding large hydrophobic ligands and may be specific for sterol. The predicted structure of the VASt domain is a two-layer sandwich alpha beta fold, also called 'helix grip fold', containing three alpha helices (alpha1 to 3), six beta-sheets (beta1 to 6) and two loops (omega1 and 2) numbered from N to C terminus. Some proteins known to contain a VASt domain are : Plant vascular associated death1 (VAD1), a regulator of programmed cell death (PCD) harboring a GRAM putative lipid-binding domain. Yeast SNF1 Interacting Protein 3 (SIP3), may be involved in sterol transfer between intracellular membranes. Yeast Suicide Protein 1 (YSP1), a mitochondrial protein specifically required for the mitochondrial thread-grain transition, de-energization, and the cell death. May be involved in sterol transfer between intracellular membranes. Yeast Suicide Protein 2 (YSP2), a mitochondrial membrane protein involved in mitochondrial fragmentation and may be involved in sterol transfer between intracellular membranes.It is also found in human GramD1a-c.

C2 and GRAM domain-containing protein Pleckstrin Homology-Glucosyltransferases, Rab-like GTPase activators and Myotubularins (PH-GRAM) domain; C2GRAM contains two N-terminal C2 domains followed by a single PH-GRAM domain. Since it contains both of these domains it is assumed that this gene cross-links both calcium and phosphoinositide signaling pathways. In general he C2 domain is involved in binding phospholipids in a calcium dependent manner or calcium independent manner. The GRAM domain is found in glucosyltransferases, myotubularins and other putative membrane-associated proteins. The GRAM domain is part of a larger motif with a pleckstrin homology (PH) domain fold.

 142-233 1.68e-09

Pleckstrin Homology-Glucosyltransferases, Rab-like GTPase activators and Myotubularins (PH-GRAM) domain; 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.

Autophagy-related protein 26/Sterol 3-beta-glucosyltransferase Pleckstrin homology (PH) domain, ...
 141-229 2.28e-09

Autophagy-related protein 26/Sterol 3-beta-glucosyltransferase Pleckstrin homology (PH) domain, repeat 2; ATG26 (also called UGT51/UDP-glycosyltransferase 51), a member of the glycosyltransferase 28 family, resulting in the biosynthesis of sterol glucoside. ATG26 in decane metabolism and autophagy. There are 32 known autophagy-related (ATG) proteins, 17 are components of the core autophagic machinery essential for all autophagy-related pathways and 15 are the additional components required only for certain pathways or species. The core autophagic machinery includes 1) the ATG9 cycling system (ATG1, ATG2, ATG9, ATG13, ATG18, and ATG27), 2) the phosphatidylinositol 3-kinase complex (ATG6/VPS30, ATG14, VPS15, and ATG34), and 3) the ubiquitin-like protein system (ATG3, ATG4, ATG5, ATG7, ATG8, ATG10, ATG12, and ATG16). Less is known about how the core machinery is adapted or modulated with additional components to accommodate the nonselective sequestration of bulk cytosol (autophagosome formation) or selective sequestration of specific cargos (Cvt vesicle, pexophagosome, or bacteria-containing autophagosome formation). The pexophagosome-specific additions include the ATG30-ATG11-ATG17 receptor-adaptors complex, the coiled-coil protein ATG25, and the sterol glucosyltransferase ATG26. ATG26 is necessary for the degradation of medium peroxisomes. It contains 2 GRAM domains and a single PH domain. PH domains are only found in eukaryotes. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. PH domains also have diverse functions. They are often involved in targeting proteins to the plasma membrane, but few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.
