Function of the spliceosome
WebWhat is the function of the spliceosome? The spliceosome removes the introns and joins the exons to form the mature transcript. In eukaryotic gene regulation, RNA interference occurs through the action of microRNAs that block translation of specific mRNA molecules. Web1 day ago · The spliceosome is a large noncoding RNA–protein complex composed of U-rich five major ( U1, U2, U4, U5, U6) and several minor small nuclear RNAs (snRNAs), core small nuclear ribonucleoproteins (snRNPs), and a myriad of auxiliary RNA-binding proteins (RBPs; Wang & Brendel, 2004 ).

WebMay 25, 2024 · The second class, which we discover in this study, includes the auxiliary, exonic remnants of canonical splice sites subsequent to intron removal. Crucially, these are weak and are not expected to function as autonomous splice sites, but they can nevertheless become substantially activated under EJC loss-of-function conditions.
