RNA-mediated control of bacterial gene expression: role of regulatory non-coding RNAs
Résumé
Regulatory noncoding RNAs are found in 5′ untranslated regions of messengers RNAs, or as individual molecules transcribed from the complementary DNA strand to annotated genes (antisense RNAs) or from empty chromosomal regions (noncoding RNAs). They can regulate each step of gene expression by directly acting on transcription or translation processes via alternative folding, base-pairing to RNA targets, or binding to regulatory proteins.
