Abstract:
The box H/ACA ribonucleoproteins (RNPs) are protein-RNA complexes responsible for pseudouridylation, the most abundant post-transcriptional modification of cellular RNAs. Integrity of its box H/ACA domain is also essential for assembly and stability of the human telomerase RNP. The recent publication of the complete box H/ACA RNP structures combined with the previously reported structures of the protein and RNA components makes it possible to deduce the structural accommodation that accompanies assembly of the full particle. This analysis reveals how the protein components distort the RNA component of the RNP, enabling productive docking of the substrate RNA into the enzymatic active site.

01:23Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...
