Gal promoter in yeast
WebA beta galactosidase reporter plasmid for the expression of genes in Saccharomyces cerevisiae yeast cells. The beta galactosidase reporter is driven by the yeast TPI promoter which is a strong constitutive promoter. The plasmid contains the TEF1 promoter to drive the expression of a gene of interest. WebThe GAL4-UAS system is a biochemical method used to study gene expression and function in organisms such as the fruit fly.It is based on the finding by Hitoshi Kakidani and Mark Ptashne, and Nicholas Webster and Pierre Chambon in 1988 that Gal4 binding to UAS sequences activates gene expression. The method was introduced into flies by Andrea …

WebThough the CYC1 promoter is fully induced in yeast grown in glycerol medium, UASC-GAL chimeric promoters containing UASG were repressed as much as 400-fold (UASC-GAL1) or 1350-fold (UASC-GAL10) in this growth medium. Several distinct portions of the GAL1-GAL10 divergent promoter region blocked the UASC-induced expression of the GAL1 …
