MSH: Short chains of RNA (100-300 nucleotides long) that are abundant in the nucleus and usually complexed with proteins in snRNPs (RIBONUCLEOPROTEINS, SMALL NUCLEAR). Many function in the processing of messenger RNA precursors. Others, the snoRNAs (RNA, SMALL NUCLEOLAR), are involved with the processing of ribosomal RNA precursors.,CSP: short chains of RNA (100-300 nucleotides long) that are abundant in the nucleus and usually complexed with proteins in small nuclear ribonucleoproteins; many function in the processing of messenger RNA precursors; others, the small nucleolar RNAs, are involved with the processing of ribosomal RNA precursors.,NCI: A small RNA molecule (100-300 nucleotides) located in the cell nucleus. This nucleic acid plays a role in RNA splicing, transcriptional regulation, telomere maintenance and rRNA modification.
