MeSH Heading: RNA, Small Nuclear
Tree Number(s): D13.444.735.628.818; D13.444.735.790.552.937
Unique ID: D012342
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D012342
Scope Note: 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.
