Spliceosomal introns are noncoding DNA sequences located between exons in many eukaryotic protein-coding genes. Most are ...

One of the most long-standing, fundamental mysteries of biology surrounds the poorly understood origins of introns. Introns are segments of noncoding DNA that must be removed from the genetic code ...

In the genome, genes that code for protein are often divided into sections called exons, which are separated by spacers called introns. When a region of DNA is transcribed into messenger RNA (mRNA) or ...

Biologists have discovered a new type of RNA-splicing regulation that helps to determine which protein-coding exons will be included in messenger RNA transcripts. RNA splicing is a cellular process ...

Researchers at the University of Toronto's Donnelly Center for Cellular and Biomolecular Research have found nearly one million new exons—stretches of DNA that are expressed in mature RNA—in the human ...

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 ...

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 you may not appreciate them, or have even heard of them, throughout your body, countless microscopic machines called spliceosomes are hard at work. As you sit and read, they are faithfully ...

Researchers confirm that the established pre-mRNA splicing mechanism that appears in textbooks cannot work in a subset of human short introns: A novel SAP30BP–RBM17 complex-dependent splicing has been ...

A new study points to introners, one of several proposed mechanisms for the creation of introns, as an explanation for the origins of most introns across species. One of the most long-standing, ...
