WebJul 4, 2024 · In mammalian cells, the majority of promoters do not appear to contain functional TATA elements as they are only present in about 10–15% of all mammalian core promoters. 34 A more recent study in CHO shows that only about 7% of all promoters possess a TATA box. 17 In the absence of TATA boxes, the transcription factor Sp1 in … WebUbiquitous Promoters are available as native or composite promoter: Native promoters, also called minimal promoters, consist of a single fragment from the 5’ region of a given gene. Each of them comprises a core promoter and its natural 5’UTR. In some cases, the 5’UTR contains an intron. Composite promoters combine promoter elements of ...

[2] WebMay 12, 2010 · Most promoters have fairly consistent strengths across different cell types, but the CMV promoter can vary considerably from cell type to cell type. At maximal induction, the TRE promoter is comparable to a strong constitutive promoter. These results should facilitate more rational choices of promoters in ectopic gene expression studies. golfhouse cz
