    4. These data show that Ncr1p and Npc2p proteins promote microautophagy in stationary phase and under nitrogen starvation conditions, likely by increasing sterol in the limiting membrane of the vacuole.
      Title: Niemann-Pick type C proteins promote microautophagy by expanding raft-like membrane domains in the yeast vacuole.
    5. Data show that Npc2p is evolutionarily related to the mammalian NPC2 family of proteins, and is treated similarly to human NPC2 when expressed in mammalian cells.
      Title: Saccharomyces cerevisiae Npc2p is a functionally conserved homologue of the human Niemann-Pick disease type C 2 protein, hNPC2.
