The yeast deletion project, formally the Saccharomyces Genome Deletion Project, is a project to create data for a near-complete collection of gene-deletion mutants of the yeast Saccharomyces cerevisiae. Each strain carries a precise deletion of one of the genes in the genome. This allows researchers to determine what each gene does by comparing ...
Delitto perfetto (Italian: [deˈlitto perˈfɛtto]) is a genetic technique for in vivo site-directed mutagenesis in yeast. This name is the Italian term for "perfect murder", and it refers to the ability of the technique to create desired genetic changes without leaving any foreign DNA in the genome.
Gene knockout by mutation is commonly carried out in bacteria. An early instance of the use of this technique in Escherichia coli was published in 1989 by Hamilton, et al. [2] In this experiment, two sequential recombinations were used to delete the gene.
In genetics, Flp-FRT recombination is a site-directed recombination technology, increasingly used to manipulate an organism's DNA under controlled conditions in vivo.It is analogous to Cre-lox recombination but involves the recombination of sequences between short flippase recognition target (FRT) sites by the recombinase flippase (Flp) derived from the 2 μ plasmid of baker's yeast ...
This is achieved by analyzing the proteome and metabolome in a genome-wide collection of yeast gene deletion strains. [11] [12] Microbial cytogenetics. The group found that aneuploidy (abnormal chromosome number) is tolerated in yeast through a mechanism of dosage compensation: the expression of genes on aneuploid chromosomes is adjusted so as ...
In yeast, deletion strains are frequently used to assess protein stability over time with cycloheximide chases. For example, yeast strains lacking critical degradation machinery such as chaperones, E3 ligases, and vacuolar proteins are often used to determine the mechanism of degradation for a protein substrate of interest.
Network-based methods: Statistical methods that take the underlying structure of gene networks into account, representing either associative or causative interactions or dependencies among gene products. [32] Weighted gene co-expression network analysis is widely used for identifying co-expression modules and intramodular hub genes. Modules may ...
Figure 1: Principle of RMCE: exchange of genetic cassettes (´flip´ step) is enabled by a recombinase (´Flp´) from yeast. Part B shows mutants (Fn) of the naturally occurring 48 bp FRT -site (F). If a gene cassette is flanked by a set of these sites (F and Fn, for example) it can change places, by double-reciprocal recombination, with a ...
