Cortistatin A is a High‐Affinity Ligand of Protein Kinases ROCK, CDK8, and CDK11

Antiproliferative alkaloid: Cortistatin A is a high-affinity ligand for a small set of protein kinases including Rho-associated, coiled-coil-containing protein kinase (ROCK), cyclin-dependent kinase 8 (CDK8), and cyclin-dependent kinase 11 (CDK11). Models of cortistatin A bound to a crystallographic structure of ROCK (see picture) and a homology model of CDK8 are presented.
