WebAug 1, 2024 · P-bodies (PBs) are cytosolic RNP granules that are conserved among eukaryotic organisms. In the past few years, major progress has been made in understanding the biochemical and biophysical mechanisms that lead to their formation. However, whether they play a role in mRNA storage or decay remains actively debated. WebFeb 1, 2024 · Although each sRNA pathway possesses specific characteristics in terms of biogenesis and accessory proteins, the fundamental mechanism of RNA silencing falls into a few common steps: (i) induction by dsRNA, (ii) dsRNA processing by DICER-LIKE (DCL) into sRNA duplexes, (iii) sRNA methylation by HUA ENHANCER1 (HEN1), and (iv) …
