Webb小核RNA（英語： small nuclear RNA ，常見縮寫為snRNA，也見譯為核内小RNA），是含有100到300碱基的RNA。. 它參與真核生物 细胞核中RNA的加工。 snRNA和許多蛋白質結合在一起成为小胞核核糖核蛋白（snRNPs即small nuclear ribonucleoproteins），參與信使RNA前體（pre-mRNA）的剪接，使後者成為成熟mRNA。 WebbEukaryotic pre-mRNAs have their introns spliced out by spliceosomes made up of small nuclear ribonucleoproteins. In complex eukaryotic cells, one primary transcript is able to prepare large amounts of mature mRNAs due to alternative splicing. Alternative splicing is regulated so that each mature mRNA may encode a multiplicity of proteins.
WebbThis genetic interaction could also be demonstrated in an in vitro crosslinking assay. These results show that a U4/U6atac di-snRNP can correctly splice a U12-dependent intron and suggest that the specificity for spliceosome type resides in the U6 and U6atac small nuclear ribonucleoproteins.

Webb24 maj 2010 · F1000 Biology Reports Splicing of the precursors of eukaryotic mRNA and some non-coding RNAs is catalyzed by the ‘spliceosome’, which comprises five RNA-protein complexes (small nuclear ribonucleoproteins, or snRNPs) that assemble in an ordered manner onto precursor-mRNAs.
Webb13 maj 2024 · The spliceosome complex is composed of five small nuclear ribonucleoproteins (snRNPs) (U1, U2, U4, U5, and U6). Splicing is performed by a cycle of assembly and disassembly of the spliceosome complex.
