The Vps13 protein family is highly conserved in eukaryotic cells. Mutations in human VPS13 genes result in a variety of diseases, such as chorea acanthocytosis (ChAc), but the cellular functions of Vps13 proteins are not well defined. In yeast, there is a single VPS13 orthologue, which is required for at least two different processes: protein sorting to the(More)
BACKGROUND Schizosaccharomyces pombe pik1 encodes a phosphatidylinositol 4-kinase, reported to bind Cdc4, but not Cdc4(G107S). PRINCIPAL FINDINGS Gene deletion revealed that pik1 is essential. In cells with pik1 deleted, ectopic expression of a loss-of-function allele, created by fusion to a temperature-sensitive dihydrofolate reductase, allowed normal(More)
The Vps13 protein family is highly conserved in eukaryotic cells. In humans, mutations in the gene encoding the family member VPS13A lead to the neurodegenerative disorder chorea-acanthocytosis. In the yeast Saccharomyces cerevisiae, there is just a single version of VPS13, thereby simplifying the task of unraveling its molecular function(s). While VPS13(More)
