Publication Abstract from PubMed
Sec14 family homologs are the major yeast phosphatidylinositol/phosphatidylcholine transfer proteins regulating lipid metabolism and vesicle trafficking. The structure of Saccharomyces cerevisiae Sfh3 displays a conserved Sec14 scaffold and reveals determinants for the specific recognition of phosphatidylinositol ligand. Apo-Sfh3 forms a dimer through the hydrophobic interaction of gating helices. Binding of phosphatidylinositol leads to dissociation of the dimer into monomers in a reversible manner. This study suggests that the substrate induced dimer-monomer transformation is an essential part of lipid transfer cycles by Sfh3.
