Spliceosome
Spliceosome — A complex of RNA and protein that removes introns from pre-mRNA, relevant to understanding how alternative splicing generates peptide isoforms.
What Is a Spliceosome?
The spliceosome is a large ribonucleoprotein complex that removes introns from pre-mRNA through RNA splicing. In peptide research, spliceosome modulation affects the production of peptide hormone isoforms (e.g., IGF-1 splice variants, calcitonin/CGRP alternative splicing) and is a target for splicing-modulator peptides in RNA therapeutics.
Peptide Connections
- IGF-1 splicing: Alternative splicing produces MGF (IGF-1Ec) vs. IGF-1Ea isoforms
- Calcitonin gene: Alternative splicing in thyroid produces calcitonin; in neurons produces CGRP
- Splicing peptides: Short peptides that modulate splice site selection for RNA-targeted therapeutics
