Scientists have discovered that some tiny segments of RNA thought to be junk instead have a functional role in suppressing production of certain messenger RNAs and appear to help cells respond to ...

Although the participation of spliceosomes is almost always required for intron removal, a few types of genes have self-splicing RNA introns.

Human introns have extensively varying lengths. Previously, only U2AF-dependent splicing was known. Researchers from Fujita Health University now show that splicing in a subset of human short introns ...

The discovery of a single intron with aberrant splice boundaries in the primitive protozoan Giardia, raises questions about the origins of splicing. In September 19 Nature, Simpson and colleagues ...
