Definition of spliceosome
a dynamic complex of RNA and protein subunits that removes introns from precursor mRNA
Examples of spliceosome in the following topics:
- SpliceosomeThe splicing of messenger RNA is accomplished and catalyzed by a macro-molecule complex known as the spliceosome.
- The areas for ligation and cleavage are determined by the many sub-units of the spliceosome which include the branch site (A) and the 5' and 3' splice sites.
- Interactions between these sub-units and the small nuclear ribonucleoproteins (snRNP) found in the spliceosome create a spliceosome A complex which helps determine which introns to leave out and which exons to keep and bind together.
