The binding and phosphorylation of serine–arginine-rich (SR) proteins by SR protein kinases (SRPKs) is essential to regulate target gene expression, however, the efficient inhibition of this interaction and phosphorylation remains underexplored. Here, the authors develop a covalent inhibitor that targets the lysine residue within the SRPK-specific docking groove, to block interaction and phosphorylation of the prototypic SR protein SRSF1.
