AZF1 is a glucose-dependent positive regulator of CLN3 transcription in Saccharomyces cerevisiae.
Transcription of the CLN3 G(1) cyclin in Saccharomyces cerevisiae is positively regulated by glucose in a process that involves a set of DNA elements with the sequence AAGAAAAA (A(2)GA(5)). To identify proteins that interact with these elements, we used a 1-hybrid approach, which yielded a nuclear zinc finger protein previously identified as Azf1. Gel shift and chromatin immunoprecipitation exp...
متن کاملA positive regulator of mitosis, Sok2, functions as a negative regulator of meiosis in Saccharomyces cerevisiae.
The choice between meiosis and alternative developmental pathways in budding yeast depends on the expression and activity of transcriptional activator Ime1. The transcription of IME1 is repressed in the presence of glucose, and a low basal level of IME1 RNA is observed in vegetative cultures with acetate as the sole carbon source. IREu, a 32-bp element in the IME1 promoter, exhibits upstream ac...
متن کاملPositive and negative autoregulation of REB1 transcription in Saccharomyces cerevisiae.
Reb1p is a DNA binding protein of Saccharomyces cerevisiae that has been implicated in the activation of transcription by polymerase (Pol) II, in the termination of transcription by Pol I, and in the organization of nucleosomes. Studies of the transcriptional control of the REB1 gene have led us to identify three Reb1p binding sites in the 5' region of the its gene, termed A, B, and C, at posit...
متن کاملSaccharomyces cerevisiae BUR6 encodes a DRAP1/NC2alpha homolog that has both positive and negative roles in transcription in vivo.
BUR3 and BUR6 were identified previously by selecting for mutations that increase transcription from an upstream activating sequence (UAS)-less promoter in Saccharomyces cerevisiae. The bur3-1 and bur6-1 mutations are recessive, increase transcription from a suc2 delta uas allele, and cause other mutant phenotypes, suggesting that Bur3p and Bur6p function as general repressors of the basal tran...
متن کاملGene Transcription in Saccharomyces cerevisiae
Several highly inducible enzyme activities are required for the degradation of allantoin in Saccharomyces cerevisiae. Induction of these pathway enzymes has been shown to be regulated at transcription, and response to inducer is lost in dal81 and dal82/durM mutants. The similar phenotypes generated by da)81 and dal82 mutations prompted the question of whether they were allelic. We demonstrated ...
