We previously described the use of quantitative proteomics to study macromolecular complexes. Applying the method to analyze a yeast RNA polymerase II preinitiation complex, we identified a new 8-kDa protein, encoded by the uncharacterized open reading frame YDR079c-a, as a potential new component of the preinitiation complex. Here we show that YDR079c-a is a bona fide component of polymerase II preinitiation complexes and investigate its role in transcription. YDR079c-a is recruited to promoter ...[more]
Project description:New1 is not an essential gene but its deletion shows a cold-sensitive phenotype in yeast Saccharomyces cerevisiae. In this study, we compare the NEW1 knockout effect on translation using Ribo-Seq and RNA-Seq analyses.
Project description:MNase-seq Experiments from Calorie Restricted and Non-Restricted Yeast from WT, ISW2DEL and ISW2K215R strains We used MNase-seq to study genome-wide nucleosome positions under Calorie Restricted and Non-restricted Saccharomyces cerevisiae
Project description:In this study we have deleted four metabolic genes (HIS3, LEU2, URA3 and MET15) in their sixteen possible combinations. These strains are following: knockout of HIS3, LEU2, URA3, MET15; knockout of HIS3, LEU2, MET15; knockout of HIS3, URA3, MET15; knockout of LEU2, URA3, MET15; knockout of HIS3, LEU2, URA3; knockout of HIS3, MET15; knockout of LEU2, MET15; knockout of URA3, MET15; knockout of HIS3, LEU2; knockout of HIS3, URA3; knockout of LEU2, URA3; knockout of MET15, knockout of HIS3; knockout of LEU2; knockout of URA3 and prototrophic strain. We grew the 16 strains in synthetic complete media (SC), and sampled for transcriptomincs in triplicates at mid-exponential phase (OD value of 0.8).
