miRNA processing turned upside down.
MicroRNAs are 19-22 nt-long RNAs that regulate eukaryotic gene expression. They are processed from stem-loop containing precursor transcripts by RNAse III enzymes of the Dicer family. In this issue of the EMBO Journal, a study by Bologna and colleagues investigates the processing of two plant MIRNA families with unusually long precursors. Their findings suggest a non-canonical mode of biogenesi...
متن کاملMicroRNAs, macrocontrol: regulation of miRNA processing.
MicroRNAs (miRNAs) are a set of small, non-protein-coding RNAs that regulate gene expression at the post-transcriptional level. Maturation of miRNAs comprises several regulated steps resulting in approximately 22-nucleotide single-stranded mature miRNAs. Regulation of miRNA expression can occur both at the transcriptional level and at the post-transcriptional level during miRNA processing. Rece...
متن کاملmiRNA Processing: Dicer-1 Meets Its Match
July 2005 | Volume 3 | Issue 7 | e259 | e244 Cell membranes are largely made of proteins, and membrane proteins account for about a third of all genes. Despite their importance, they are devilishly hard to isolate and stabilize, and therefore are hard to study. The problem lies in their structure: membrane proteins have at least one hydrophobic domain, composed of a stretch of waterrepelling am...
متن کاملPosttranslational Regulation of Smads.
Transforming growth factor β (TGF-β) family signaling dictates highly complex programs of gene expression responses, which are extensively regulated at multiple levels and vary depending on the physiological context. The formation, activation, and destruction of two major functional complexes in the TGF-β signaling pathway (i.e., the TGF-β receptor complexes and the Smad complexes that act as c...
متن کاملGlobal profiling of miRNAs and the hairpin precursors: insights into miRNA processing and novel miRNA discovery
MicroRNAs (miRNAs) constitute an important class of small regulatory RNAs that are derived from distinct hairpin precursors (pre-miRNAs). In contrast to mature miRNAs, which have been characterized in numerous genome-wide studies of different organisms, research on global profiling of pre-miRNAs is limited. Here, using massive parallel sequencing, we have performed global characterization of bo...
