MeSH Heading: RNA Caps
Tree Number(s): D03.633.100.759.646.454.700; D13.444.735.544.500; D13.695.667.454.700; D13.695.827.426.700
Unique ID: D012315
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D012315
Annotation: IM; /‌drug eff /‌ultrastruct permitted
Scope Note: Nucleic acid structures found on the 5' end of eukaryotic cellular and viral messenger RNA and some heterogeneous nuclear RNAs. These structures, which are positively charged, protect the above specified RNAs at their termini against attack by phosphatases and other nucleases and promote mRNA function at the level of initiation of translation. Analogs of the RNA caps (RNA CAP ANALOGS), which lack the positive charge, inhibit the initiation of protein synthesis.
Entry Term(s): 5' Capped RNA; 5' mRNA Cap Structure; RNA Cap
Registry Numbers: 0
NLM Classification #: QU 58.7
Previous Indexing: Guanine Nucleotides (1966-1971); Guanosine Triphosphate (1972-1974)/analogs & derivatives (1975-1979); Oligoribonucleotides (1976-1979); Ribonucleotides (1971-1975); RNA, Messenger (1966-1979)
