WebAbstract Mammalian Staufen (Stau)1 is an RNA binding protein that is thought to function in mRNA transport and translational control. Nonsense-mediated mRNA decay (NMD) degrades abnormal and natural mRNAs that terminate translation sufficiently upstream of a splicing-generated exon-exon junction. WebOne mechanism by which this happens is the Staufen 1 mediated decay. Staufen 1 (STAU1) protein binds the 3′UTR that contain duplex RNA structures to mediate mRNA decay and regulate gene expression . LncRNAs have been found to form STAU1 binding sites by interacting with the 3′UTR of coding genes, ...

WebAbstract Nonsense-mediated mRNA decay (NMD) is a translation-coupled mechanism that eliminates mRNAs containing premature translation-termination codons (PTCs). In mammalian cells, NMD is also linked to pre-mRNA splicing, as in many instances strong mRNA reduction occurs only when the PTC is located upstream of an intron. WebMay 19, 2024 · Nonsense-mediated RNA decay (NMD) was originally discovered as a cellular surveillance pathway that safeguards the quality of mRNA transcripts in eukaryotic cells. In its canonical function, NMD prevents translation of mutant mRNAs harboring premature termination codons (PTCs) by targeting them for degradation. germans learning a second language memeWebStaufen is a dsRNA-binding protein involved in many aspects of RNA regulation, such as mRNA transport, Staufen-mediated mRNA decay and the regulation of mRNA translation.
