    Description: Diploid cells of budding yeast produce haploid cells through the developmental program of sporulation, which consists of meiosis and spore morphogenesis. DNA microarrays containing nearly every yeast gene were used to assay changes in gene expression during sporulation. At least seven distinct temporal patterns of induction were observed. The transcription factor Ndt80 appeared to be important for induction of a large group of genes at the end of meiotic prophase. Consensus sequences known or proposed to be responsible for temporal regulation could be identified solely from analysis of sequences of coordinately expressed genes. The temporal expression pattern provided clues to potential functions of hundreds of previously uncharacterized genes, some of which have vertebrate homologs that may function during gametogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chu, S -- DeRisi, J -- Eisen, M -- Mulholland, J -- Botstein, D -- Brown, P O -- Herskowitz, I -- AI18738/AI/NIAID NIH HHS/ -- GH00450/GH/CGH CDC HHS/ -- GM46406/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1998 Oct 23;282(5389):699-705.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Biophysics, University of California, San Francisco, San Francisco, CA 94143-0448, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9784122" target="_blank"〉PubMed〈/a〉

    Description: Here a method is described to identify genes encoding proteins that recognize a specific DNA sequence. A bank of random protein segments tagged with a transcriptional activation domain is screened for proteins that can activate a reporter gene containing the sequence in its promoter. This strategy was used to identify an essential protein that interacts in vivo with the yeast origin of DNA replication. Matches between its predicted amino acid sequence and peptide sequence obtained from the 50-kilodalton subunit of the yeast origin recognition complex (ORC) established that the gene isolated here, ORC6, encodes this subunit. These observations provide evidence that ORC recognizes yeast replication origins in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, J J -- Herskowitz, I -- AI18738/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1993 Dec 17;262(5141):1870-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Biophysics, University of California, San Francisco 94143-0448.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8266075" target="_blank"〉PubMed〈/a〉

    Description: The events of the eukaryotic cell cycle are governed by cyclin-dependent kinases (cdk's), whose activation requires association with cyclin regulatory subunits expressed at specific cell cycle stages. In the budding yeast Saccharomyces cerevisiae, the cell cycle is thought to be controlled by a single cdk, CDC28. Passage through the G1 phase of the cell cycle is regulated by complexes of CDC28 and G1 cyclins (CLN1, CLN2, and CLN3). A putative G1 cyclin, HCS26, has recently been identified. In a/alpha diploid cells lacking CLN1 and CLN2, HCS26 is required for passage through G1. HCS26 does not associate with CDC28, but instead associates with PHO85, a closely related protein kinase. Thus, budding yeast, like higher eukaryotes, use multiple cdk's in the regulation of cell cycle progression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Espinoza, F H -- Ogas, J -- Herskowitz, I -- Morgan, D O -- AI18738/AI/NIAID NIH HHS/ -- CA52481/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1994 Nov 25;266(5189):1388-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology, University of California, San Francisco 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973730" target="_blank"〉PubMed〈/a〉

    Description: Induction of the yeast gene PHO5 is mediated by the transcription factors PHO2 and PHO4. PHO5 transcription is not detectable in high phosphate; it is thought that the negative regulators PHO80 and PHO85 inactivate PHO2 and PHO4. Here it is reported that PHO80 has homology to yeast cyclins and interacts with PHO85, a p34cdc2/CDC28-related protein kinase. The PHO80-PHO85 complex phosphorylates PHO4; this phosphorylation is correlated with negative regulation of PHO5. These results demonstrate the existence of a cyclin-cdk complex that is used for a regulatory process other than cell-cycle control and identify a physiologically relevant substrate for this complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaffman, A -- Herskowitz, I -- Tjian, R -- O'Shea, E K -- New York, N.Y. -- Science. 1994 Feb 25;263(5150):1153-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Medicine, Department of Biochemistry and Biophysics, University of California at San Francisco 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8108735" target="_blank"〉PubMed〈/a〉
