    Summary
    Enables phosphatidylinositol transfer activity and sterol binding activity. Involved in several processes, including negative regulation of sexual sporulation resulting in formation of a cellular spore; phospholipid transport; and sterol biosynthetic process. Located in cell periphery; lipid droplet; and nucleus-vacuole junction. [provided by Alliance of Genome Resources, Dec 2024]

    What's a GeneRIF?
    1. Overexpression of a lipid-binding defective mutant of phosphatidylinositol transporter (PDR16) does not confer the resistance to aureobasidin A (AbA), indicating that the lipid-binding activity is essential for acquiring resistance to AbA. In AbA-treated cells, but not in cells in which AUR1 is repressed by the tetracycline-regulatable promoter, the reductions of complex sphingolipid levels are suppressed by the PDR16.
      Title: Overexpression of PDR16 confers resistance to complex sphingolipid biosynthesis inhibitor aureobasidin A in yeast Saccharomyces cerevisiae.
    2. The increased susceptibility to azoles, and enhanced changes in sterol biosynthesis upon exposure to azoles of the pdr16Delta strain compared to wt strain, are not the results of increased intracellular concentration of azoles in the pdr16Delta cells.
      Title: The yeast Saccharomyces cerevisiae Pdr16p restricts changes in ergosterol biosynthesis caused by the presence of azole antifungals.
    3. The dimeric structure of Sfh3 (Sec14 family homologue 3 in yeast) is reported for the first time and differs from the Sec14 proteins reported to date.
      Title: Dimeric Sfh3 has structural changes in its binding pocket that are associated with a dimer-monomer state transformation induced by substrate binding.
    4. Substrate induced dimer-monomer transformation is an essential part of lipid transfer cycles by Sfh3.
