(Submitter supplied) In S. cerevisiae, the forkhead transcription factor Hcm1 has been involved in chromosome segregation, spindle pole dynamics and budding. We found that, in response to oxidative stress stimuli, Hcm1 shifts from cytoplasm to the nucleus, interacting with the histone deacetylase Sir2, which regulates Hcm1 localization. Hcm1-overexpressing cells showed increased resistance to oxidative stress which can be attributed to increased catalase and Sod2 activities. more...

(Submitter supplied) There are about 800 genes in Saccharomyces cerevisiae whose transcription is cell-cycle regulated. Some of these form clusters of co-regulated genes. The 'CLB2' cluster contains 33 genes whose transcription peaks early in mitosis, including CLB1, CLB2, SWI5, ACE2, CDC5, CDC20 and other genes important for mitosis. Here we find that the genes in this cluster lose their cell cycle regulation in a mutant that lacks two forkhead transcription factors, Fkh1 and Fkh2. more...

(Submitter supplied) Analysis of gene expression across the cell cycle from wild type cells, and cells expressing alleles of Yox1, Yhp1, Hcm1, and Tos4 that cannot be phosphorylated by Cdk1. Expression of S-phase and M/G1 transcripts are downregulated when phosphorylation of these factors is blocked, demonstrating that Cdk1 promotes expression of late cell cycle genes.

(Submitter supplied) The replication of eukaryotic chromosomes is organized temporally and spatially within the nucleus through epigenetic regulation of replication origin function. The characteristic initiation timing of specific origins is thought to reflect their chromatin environment or sub-nuclear positioning, however the mechanism remains obscure. Here we show that the yeast Forkhead transcription factors, Fkh1 and Fkh2, are global determinants of replication origin timing. more...

(Submitter supplied) Forkhead box (FOX) transcription factors regulate a wide variety of cellular functions in higher eukaryotes, including cell cycle control and developmental regulation. In Saccharomyces cerevisiae, Forkhead proteins Fkh1 and Fkh2 perform analogous functions, regulating genes involved in cell cycle control, while also regulating matingtype silencing and switching involved in gamete development. Recently, we revealed a novel role for Fkh1 and Fkh2 in the regulation of replication origin initiation timing, which, like donor preference in mating-type switching, appears to involve long-range chromosomal interactions, suggesting roles for Fkh1 and Fkh2 in chromatin architecture and organization. more...

(Submitter supplied) Two homeodomain proteins, Yox1 and Yhp1, act as repressors at early cell cycle boxes (ECBs) to restrict their activity to the M/G1 phase of the cell cycle in budding yeast. These proteins bind to Mcm1 and to a typical homeodomain binding site. The expression of Yox1 is periodic and directly correlated with its binding to, and repression of, ECB activity. The absence of Yox1 and Yhp1 or the constitutive expression of Yox1 leads to the loss of cell-cycle regulation of ECB activity. more...

(Submitter supplied) Genetic and environmental factors influence the phenotype of an organism. Time is rarely considered when studying changes in cellular phenotype. Time-resolved microarray data revealed genome-wide transcriptional changes in cells oscillating with ~2 and ~4 h periods. We mapped the global patterns of transcriptional oscillations into a 3-dimensional map to represent different cellular phenotypes of oscillation period. more...
