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 ...

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

Each mRNA transcript contains coding regions, known as exons, and noncoding regions, known as introns. They also include sites that act as signals for where splicing should occur, allowing the cell to ...

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 ...
