Very-long-chain fatty acid-containing phospholipids accumulate in fatty acid synthase temperature-sensitive mutant strains of the fission yeast Schizosaccharomyces pombe fas2/lsd1.


Fission yeast lsd1 strains show aberrant mitosis with a lsd phenotype, large and small daughter nuclei, and a very thick septum, the phenotypic expression being temperature-sensitive. The lsd1(+) gene is the homologue of the budding yeast FAS2 gene encoding the fatty acid synthase alpha-subunit as reported previously (S. Saitoh, K. Takahashi, K. Nabeshima… (More)
