Bacterial Small RNA Regulators

Proteins that interact with bacterial small RNA regulators.

Small regulatory RNAs have been identified in a wide range of organisms, where they modify mRNA stability, translation or protein function. Small RNA regulators (sRNAs) either pair with mRNA targets or modify protein activities. Here we discuss current knowledge of the various proteins that interact with RNA regulators and review the physiologic implications of sRNA-protein complexes in DNA, RN...

Small RNA Regulators of Gene Expression

This year, the Lasker Foundation recognizes Victor Ambros, Gary Ruvkun, and David Baulcombe for their pioneering work elucidating the role of short RNA species in the posttranscriptional regulation of eukaryotic gene expression.

The small RNA regulators of Escherichia coli: roles and mechanisms*.

Small noncoding RNAs have been found in all organisms, primarily as regulators of translation and message stability. The most exhaustive searches have taken place in E. coli, resulting in identification of more than 50 small RNAs, or 1%-2% of the number of protein-coding genes. One large class of these small RNAs uses the RNA chaperone Hfq; members of this class act by pairing to target messeng...

RNA silencing: small RNAs as ubiquitous regulators of gene expression.

'RNA silencing' is the suppression of gene expression through nucleotide sequence-specific interactions that are mediated by RNA. Initially identified as an immune system that is targeted against transposons and viruses, RNA silencing is emerging as a fundamental regulatory process that is likely to affect many layers of endogenous gene expression in most, if not all, eukaryotes.
