Transcription factors driving periodic gene expression during the fission yeast cell cycle
Jordáková, Anna ; Převorovský, Martin (advisor) ; Paleček, Jan (referee)
The fission yeast Schizosaccharomyces pombe plays an important role in elucidation of the mechanisms of cell cycle regulation and characterization of the relevant effector molecules involved. The cell cycle of S. pombe consists of a prolonged period of growth (G2 phase), which is followed by a nuclear division (M phase), a very short G1 phase and DNA replication (S phase). Already during S phase formation of division septum occurs. Cell cycle progression is regulated at multiple levels. Although the yeast S. pombe is an extensively studied model organism, knowledge of the transcriptional network regulating progression through the cell cycle is still incomplete. Transcription factors are very important regulators of gene expression and therefore their characterization is the subject of research. At the transcriptional level, several key transcription factors have been identified that regulate periodically oscillating and interdependent waves of gene expression during the cell cycle. This study summarizes the current state of knowledge in the field of the transcriptional regulation of periodic gene expression in the fission yeast cell cycle.
