Colloquialism for restoration of the coronal part of a natural tooth by means of an artificial crown. 4. The nucleotide structure found at the 5' terminus of many eukaryotic messenger RNAs, consisting of a 7-methylguanosine connected, via its 5'-hydroxyl group, by a triphosphate group to the 5'-hydroxyl group of the first nucleoside encoded by the DNA; usually symbolised as m7G5'ppp5'N, where N is nucleoside number 1 in the transcribed mRNA and is often itself methylated; the cap is added posttranscriptionally.

| cap binding protein | <molecular biology, protein> Protein (24 kD) with affinity for cap structure at 5' end of mRNA that probably assists, together with other initiation factors, in binding the mRNA to the 40S ribosomal subunit. Translation of mRNA in vitro is faster if it has a cap binding protein. (18 Nov 1997) |
