What's the difference between mRNA and pre-mRNA? It's all about splicing of introns. See how one RNA sequence can exist in nearly 40,000 different forms. Next, the snRNPs U2 and U4/U6 appear to ...

Proper splicing requires efficient spliceosome assembly. Here the authors reveal that zinc finger protein 207 interacts with the U1 small nuclear ribonucleoprotein to accelerate spliceosome ...

RNA splicing is a cellular process that is critical for gene expression. After genes are copied from DNA into messenger RNA, portions of the RNA that don't code for proteins, called introns ...
