Numerous mechanisms exploit or modulate the conformational/compositional dynamics of spliceosomes to regulate splicing. The majority of higher eukaryotic protein-coding genes contain more than one intron and the derived pre-mRNAs can be alternatively spliced. Diverse principles ensure the reliable identification of authentic splice sites while concomitantly providing flexibility in splice site choice during alternative splicing. Some species contain a second type of minor (U12-type) spliceosome.
