SF3B1 phosphorylation is an evolutionarily conserved step in spliceosome activation carried out by the divergent, OTS964-insensitive kinase CRK9 in trypanosomes

The paper shows that CRK9, a trypanosome kinase, phosphorylates SF3B1 TP motifs to activate the spliceosome, conserving a function previously known in CDK11, and is insensitive to OTS964.
