WebApr 11, 2024 · Background and Objectives Zhu-Tokita-Takenouchi-Kim (ZTTK) syndrome (OMIM 617140) is a recently identified neurodevelopmental disorder caused by heterozygous loss-of-function (LoF) variants in SON . Because the SON protein functions as an RNA-splicing regulator, it has been shown that some clinical features of ZTTK … WebX chromosome inactivation (XCI) is a dynamically regulated developmental process with inactivation and reactivation accompanying the loss and gain of pluripotency, respectively. A functional relationship between pluripotency and lack of XCI has been suggested, whereby pluripotency transcription factors repress the master regulator of XCI, the noncoding …

However, because of the deep divergences involved in these comparisons, little is understood about how these changes occur, particularly in the case of intron gain. To …
Web1 day ago · The core snRNPs together with the corresponding snRNAs are directly involved in the biochemical reactions of intron excision and exon ligation of the pre-mRNA (Gehring & Roignant, 2024). Intron removal represents a key event in pre-mRNA processing, and AS combines intron removal and alternative exon ligation of the pre-mRNA, thus offering an … WebThe Δ40p53 isoforms (also named p47 or ΔNp53) are generated by alternative splicing of intron 2 and/or alternative initiation of translation. Indeed, the retention of a part of intron 2 (i2) generates a stop codon between exons 2 and 3 in the p53i2 messenger ribonucleic acid (mRNA) that leads to the initiation of translation at AUG40.

Introns may be lost or gained over evolutionary time, as shown by many comparative studies of orthologous genes. Subsequent analyses have identified thousands of examples of intron loss and gain events, and it has been proposed that the emergence of eukaryotes, or the initial stages of eukaryotic evolution, involved an intron invasion. Two definitive mechanisms of intron loss, reverse transcriptase-mediated intron loss (RTMIL) and genomic deletions, have been identified…
