Small nuclear ribonucleoproteins function
WebbWe were thus able to confirm our sRNA-seq results and determined that both doRNAs may be more abundant than microRNAs. The characterization of these RNAs led us to establish that doRNA and C-doRNA are mainly localized in the cytoplasm of cells and interact with heterogeneous nuclear ribonucleoproteins (hnRNPs) A0, A1 and A2B1, but not … WebbSmall nuclear RNAs (snRNAs) are believed to play a role in the processing of the primary transcription products of split genes, thus allowing for precise alignment and correct …
