Ergosterol 126-136 oxysterol-binding protein KES1 Saccharomyces cerevisiae S288C 78-82 16136145-2 2005 Here we report the structure of the full-length yeast ORP Osh4 (also known as Kes1) at 1.5-1.9 A resolution in complexes with ergosterol, cholesterol, and 7-, 20- and 25-hydroxycholesterol. Cholesterol 138-149 oxysterol-binding protein KES1 Saccharomyces cerevisiae S288C 58-62 16136145-2 2005 Here we report the structure of the full-length yeast ORP Osh4 (also known as Kes1) at 1.5-1.9 A resolution in complexes with ergosterol, cholesterol, and 7-, 20- and 25-hydroxycholesterol. Cholesterol 138-149 oxysterol-binding protein KES1 Saccharomyces cerevisiae S288C 78-82 16136145-7 2005 The structure of Osh4 in the absence of ligand exposes potential phospholipid-binding sites that are positioned for membrane docking and sterol exchange. Phospholipids 65-77 oxysterol-binding protein KES1 Saccharomyces cerevisiae S288C 17-21 15617515-3 2005 Current data imply that the yeast ORP Kes1p is a negative regulator of Golgi-derived vesicular transport mediated by the essential phosphatidylinositol/phosphatidylcholine transfer protein Sec14p. Phosphatidylinositols 131-151 oxysterol-binding protein KES1 Saccharomyces cerevisiae S288C 38-43 15617515-3 2005 Current data imply that the yeast ORP Kes1p is a negative regulator of Golgi-derived vesicular transport mediated by the essential phosphatidylinositol/phosphatidylcholine transfer protein Sec14p. Phosphatidylcholines 152-171 oxysterol-binding protein KES1 Saccharomyces cerevisiae S288C 38-43 15617515-5 2005 Recent studies have determined that Kes1p and ORP1S both bind phospholipids as ligands. Phospholipids 62-75 oxysterol-binding protein KES1 Saccharomyces cerevisiae S288C 36-41 15617515-9 2005 The results determined that the phospholipid binding domain per se was insufficient for inhibition of vesicular transport by ORP1S, and that transport of carboxypeptidase Y and invertase from the Golgi may be regulated differentially by specific regions of ORP1S/Kes1p. Phospholipids 32-44 oxysterol-binding protein KES1 Saccharomyces cerevisiae S288C 263-268 11916983-3 2002 Kes1p, one of seven members of the yeast OSBP family, negatively regulates Golgi complex secretory functions that are dependent on the action of the major yeast phosphatidylinositol/phosphatidylcholine Sec14p. Phosphatidylinositols 161-181 oxysterol-binding protein KES1 Saccharomyces cerevisiae S288C 0-5 11916983-3 2002 Kes1p, one of seven members of the yeast OSBP family, negatively regulates Golgi complex secretory functions that are dependent on the action of the major yeast phosphatidylinositol/phosphatidylcholine Sec14p. Phosphatidylcholines 182-201 oxysterol-binding protein KES1 Saccharomyces cerevisiae S288C 0-5 11916983-4 2002 We now demonstrate that Kes1p is a peripheral membrane protein of the yeast Golgi complex, that localization to the Golgi complex is required for Kes1p function in vivo, and that targeting of Kes1p to the Golgi complex requires binding to a phosphoinositide pool generated via the action of the Pik1p, but not the Stt4p, PtdIns 4-kinase.
