Splicing defect
WebPre-mRNA splicing is an essential mechanism for ensuring integrity of the transcriptome in eukaryotes. Therefore, splicing deficiency might cause a decrease in functional proteins and the production of nonfunctional, aberrant proteins. To prevent the production of such aberrant proteins, eukaryotic cells have several mRNA quality control mechanisms. In … Web9 Jun 2024 · Experimental splicing analyses are needed not only to determine the exact nature of splicing defects generated by splice site variants but also essential to the …

WebThe splicing mutation may occur in both introns and exons and disrupt existing splice sites or splicing regulatory sequences (intronic and exonic splicing silencers and enhancers), create new ones, or activate the cryptic ones. WebNevertheless, a point mutation in RRM2 (R263P) causes pre-mRNA splicing defects in round spermatids affecting male fertility in mice 25. A superposition of 1 H, 15 N-HSQC NMR spectra of the RRM2 ...
Web1 Jul 2024 · Variants which affect splicing are significant contributors to human disease. Splicing is the process by which introns are removed, and exons joined together in pre-mRNA processing. It is mediated by a large RNA–protein complex (the spliceosome), reliant on numerous cis and trans acting factors.
