T cells are the major arm of the immune system responsible for controlling and regressing cancers. To identify genes limiting T cell function, we conducted genome-wide CRISPR knock-out screens in human CAR-T cells. Top hits were MED12 and CCNC, components of the Mediator cyclin-dependent kinase (CDK) module. Targeted MED12 deletion enhanced anti-tumor activity and sustained the effector phenotype in CAR- and TCR-engineered T cells, and inhibition of CDK8/19 kinase activity increased expansion of non-engineered T cells. MED12 deficient T cells manifested increased core Meditator chromatin occupancy at transcriptionally active enhancers, most pronounced for STAT and AP1 transcription factors, and increased IL2RA expression and IL-2 sensitivity. These results implicate Mediator in T cell effector programming and identify the CDK module as a target for enhancing potency of anti-tumor T cell responses. The Mediator kinase module is a primary regulator of T cell effector function, and genetic or chemical inhibition of this module enhances T cell potency.
