WebThe PKR kinase activity suppresses translation by phosphorylation of initiation factors and synthesis of oligo-2′–5′ poly activates the endoribonuclease RNase L, which degrades RNA. However, neither this suppression of translation nor degradation of mRNA has been shown to be gene-specific in action. WebThe invention relates to an RNA for inhibiting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) replication. According to an aspect of the invention, the RNA is an at least partially double-stranded RNA having a sequence being at least 95 % identical to a sequence chosen from the group consisting of SEQ ID NO. 6 and SEQ ID NO.

Antisense RNAs can be classified in different ways. In terms of regulatory mechanisms, some authors group asRNAs into RNA-DNA interactions, RNA-RNA interactions either in nucleus or cytoplasm and RNA-protein interactions (epigenetic). Antisense RNAs can be categorized by the type of the promoters that initiate expression of asRNAs: independent promoters, shared bidirection… WebApr 9, 2015 · Elongation rate and pausing are determined by template sequence and RNA structure (e.g., stem-loops) and involve at least two components of the RNAP catalytic center, the bridge helix (BH) and trigger loop (TL). Elongation is proposed to occur in two steps. First, the TL folds in response to NTP binding.

WebAntisense RNA (asRNA) is an efficient means for regulating gene expression. Generally, there are two kinds of mechanisms for inhibiting target RNA translation by binding of asRNA: (1) hindering ribosome-binding site interactions with ribosomes and/or (2) stimulation of the degradation of the target RNA by ribonucleases via altering its structure. WebBy binding to specific protein partners, a noncoding transcript (green) can modulate the activity of the protein (5), serve as a structural component that allows a larger RNA–protein complex to form (6), or alter where the protein localizes in the cell (7).
