What are the functions of introns?

Posted June 22, 2020


Although introns do not encode protein products, they have very important biological functions, for example:

  • The most important function of introns is that they allow for alternative splicing, making it possible to generate multiple proteins from a single gene.
  • Some introns encode functional RNA molecules through further processing after they are spliced.
  • Introns also play essential roles in gene expression regulation such as nonsense-mediated decay and mRNA export.
