Ubiquitin-dependent proteolysis regulates gene expression in many eukaryotic systems. Pof1 is an essential fission yeast F-box protein that is homologous to budding yeast Met30. Temperature-sensitive pof1 mutants display acute growth arrest with small cell size. Extragenic suppressor analysis identified Zip1, a bZIP (basic leucine zipper) transcription(More)
Schizosaccharomyces pombe GATA factor Ams2 is responsible for cell cycle-dependent transcriptional activation of all the core histone genes peaking at G1/S phase. Intriguingly, its own protein level also fluctuates concurrently. Here, we show that Ams2 is ubiquitylated and degraded through the SCF (Skp1-Cdc53/Cullin-1-F-box) ubiquitin ligase, in which F box(More)
