Protein activity is the ultimate arbiter of function in most cellular pathways, and protein concentration is fundamentally connected to protein action. While the proteome of yeast has been subjected to the most comprehensive analysis of any eukaryote, existing datasets are difficult to compare, and there is no consensus abundance value for each protein. We evaluated 21 quantitative analyses of the S. cerevisiae proteome, normalizing and converting all measurements of protein abundance into the intuitive measurement of absolute molecules per cell. We estimate the cellular abundance of 92% of the proteins in the yeast proteome and assess the variation in each abundance measurement. Using our protein abundance dataset, we find that a global response to diverse environmental stresses is not detected at the level of protein abundance, we find that protein tags have only a modest effect on protein abundance, and we identify proteins that are differentially regulated at the mRNA abundance, mRNA translation, and protein abundance levels.

A Pilot Trial of the Immunogenicity, and Safety of GI-4000; an Inactivated Recombinant Saccharomyces Cerevisiae Expressing Mutant Ras Protein, as Consolidation Therapy Following Curative Treatment for Stage I-III Non-Small Cell Lung Cancer (NSCLC) With Tu
This is a consolidation therapy trial evaluating GI-4000 in subjects with NSCLC treated with curative intent who are disease free at their first post-treatment restaging assessment.
The purpose of this study is to further evaluate the immunogenicity and safety of 10μg/0.5ml Recombinant Hepatitis B Vaccines(Saccharomyces Cerevisiae) in the Healthy Neonates.
A relationship between IBD and spondyloarthropathy is well recognized. ASCA ( anti saccharomyces cerevisiae antibodies)are considered to be a serological marker for Crohn's disease and hav...
The eradication rate of standard quadruple therapy has become less successful due to low compliance and high resistance to the antibiotics. Therefore, it is necessary to develop new treatm...
A member of the Rho family of MONOMERIC GTP-BINDING PROTEINS from SACCHAROMYCES CEREVISIAE. It is involved in morphological events related to the cell cycle. This enzyme was formerly listed as EC 220.127.116.11.
Proteins obtained from the species SACCHAROMYCES CEREVISIAE. The function of specific proteins from this organism are the subject of intense scientific interest and have been used to derive basic understanding of the functioning similar proteins in higher eukaryotes.
A protein kinase encoded by the Saccharomyces cerevisiae CDC28 gene and required for progression from the G1 PHASE to the S PHASE in the CELL CYCLE.
A species of the genus SACCHAROMYCES, family Saccharomycetaceae, order Saccharomycetales, known as "baker's" or "brewer's" yeast. The dried form is used as a dietary supplement.
A set of nuclear proteins in SACCHAROMYCES CEREVISIAE that are required for the transcriptional repression of the silent mating type loci. They mediate the formation of silenced CHROMATIN and repress both transcription and recombination at other loci as well. They are comprised of 4 non-homologous, interacting proteins, Sir1p, Sir2p, Sir3p, and Sir4p. Sir2p, an NAD-dependent HISTONE DEACETYLASE, is the founding member of the family of SIRTUINS.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
