Biogenesis and mechanisms of microRNA‐mediated gene regulation

Rani, Varsha, Sengar, Rakesh Singh·2022·Biotechnology and Bioengineering

Abstract

Endogenous RNAs that control posttranscriptional gene expression are microRNAs (miRNAs). These small regulatory molecules play a crucial role in certain biological processes and their expression is often strictly regulated. They are small 21–24 nucleotide molecules that act as major regulators of gene expression at the posttranscriptional level. One of the mechanisms by which miRNAs control the gene expression is to interact the interaction of the seeds with the 3ʹ‐end and and more seldom the 5ʹ‐end of mRNA transcribed by the target genes. miRNAs have been identified as important cytoplasmic regulators of gene expression. miRNAs function as posttranscriptional regulators of their messenger RNA (mRNA) targets by mRNA degradation and/or translational repression. It is becoming evident, however, that miRNAs have nuclear functions as well. About the cell type, the physiological state of the body, and various external factors, the following explanation will summarize the complex multilevel regulation of miRNA expression. A better understanding of the molecular mechanisms controlling miRNA expression will provide clarification of the variations in the expression of protein‐coding genes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
