WebThe Escherichia coli small RNA SgrS controls a metabolic stress response that occurs upon accumulation of certain glycolytic intermediates. SgrS base pairs with and represses translation of ptsG and manXYZ mRNAs, which encode sugar transporters, and activates translation of yigL mRNA, encoding a sugar phosphatase. Small RNA (sRNA) are polymeric RNA molecules that are less than 200 nucleotides in length, and are usually non-coding. RNA silencing is often a function of these molecules, with the most common and well-studied example being RNA interference (RNAi), in which endogenously expressed microRNA (miRNA) or exogenously derived small interfering RNA (siRNA) induces the degradation of complementary messenger RNA.

WebSep 21, 2024 · Small interfering RNA (siRNA), also known as short interfering RNA or silencing RNA, is a type of double-stranded RNA molecules that function within the RNA interference (RNAi) pathway. It inhibits translation, hence inhibiting the expression of certain genes with complementary nucleotide sequences, by degrading mRNA after transcription.
