The splicing … WebAlternative splicing of amyloid precursor protein (APP), one of the candidate genes for Alzheimer's disease, yields three major mRNAs, which give rise to APP770, APP751 and …
Web3 Apr 2024 · Cells produce multiple mRNAs through alternative splicing, which ensures proteome diversity. Because most human genes undergo alternative splicing, key components of signal transduction pathways are no exception. Cells regulate various signal transduction pathways, including those associated with cell proliferation, development, … WebIntroduction. Alternative splicing (AS) is the mechanism that generates multiple mRNAs from the same gene, leading to proteomic and functional diversity, and it is mediated by AS factors that, by recognizing RNA sequences on immature transcripts, facilitate the inclusion or exclusion of exons and introns. 1 NOVA1 and NOVA2 proteins are AS factors initially …
Web30 Mar 2024 · We identified transcriptome-wide functional and biophysical targets of Mbnl proteins in brain, heart, muscle, and myoblasts by using RNA-seq and CLIP-seq approaches. This analysis identified several hundred splicing events whose regulation depended on Mbnl function in a pattern indicating functional interchangeability between Mbnl1 and Mbnl2.

WebSplicing depends on the presence of signal sequences in the pre-mRNA. In almost all genes, the first two nucleotides at the 5′ end of an intron are GT and the last two at the 3′ end are AG. These are part of larger signal sequences present at the 5′ and 3′ ends of the introns.
