A positive cis-acting DNA element is required for high-level transcription in Chlamydia.
The spacer A/T region is a positive cis-acting DNA element that was identified in the Chlamydia trachomatis rRNA promoter region. We have now demonstrated that similar sequences in other chlamydial promoters are important for transcription. Substitution of candidate spacer A/T regions in four chlamydial promoters decreased transcription by partially purified C. trachomatis RNA polymerase in an ...
متن کاملCis-acting elements in its 3′ UTR mediate post-transcriptional regulation of KRAS
Multiple RNA-binding proteins and non-coding RNAs, such as microRNAs (miRNAs), are involved in post-transcriptional gene regulation through recognition motifs in the 3' untranslated region (UTR) of their target genes. The KRAS gene encodes a key signaling protein, and its messenger RNA (mRNA) contains an exceptionally long 3' UTR; this suggests that it may be subject to a highly complex set of ...
متن کاملSynergistic operation of the CAR2 (Ornithine transaminase) promoter elements in Saccharomyces cerevisiae.
Dal82p binds to the UIS(ALL) sites of allophanate-induced genes of the allantoin-degradative pathway and functions synergistically with the GATA family Gln3p and Gat1p transcriptional activators that are responsible for nitrogen catabolite repression-sensitive gene expression. CAR2, which encodes the arginine-degradative enzyme ornithine transaminase, is not nitrogen catabolite repression sensi...
متن کاملCommon and unique cis-acting elements mediate xanthotoxin and flavone induction of the generalist P450 CYP321A1
How polyphagous herbivores up-regulate their counterdefense genes in response to a broad range of structurally different allelochemicals remains largely unknown. To test whether this is accomplished by having more allelochemical-response elements or the similar number of functionally more diverse elements, we mapped out the cis-acting elements mediating the induction of the allelochemical-metab...
متن کاملImpact of cis-acting elements’ frequency in transcription activity in dicot and monocot plants
The production of new cultivars via recombinant DNA technology is important in applied agriculture. Promoters play fundamental roles in successful transformation and gene expression. Fragments of the upstream regulatory region of the movement protein gene of the Tomato yellow leaf curl virus (TYLCV; two fragments) and Watermelon chlorotic stunt virus (WmCSV, two fragments) and one fragment of t...
