CDK12/13 promote splicing of proximal introns by enhancing the interaction between RNA polymerase II and the splicing factor SF3B1

36 views | May 09 2023

The article reports that dual inhibition of CDK12 and CDK13 impairs splicing of a subset of introns characterized by weak 3' splice sites located at larger distance from the branchpoint, and targeting both CDK12/13 and the spliceosome represents an exploitable anticancer approach.
