Abstract

Tumors displaying high MYC levels depend on the NUAK1 kinase. Cossa et al. show that NUAK1 binds protein phosphatase 1 (PP1) and its regulatory subunit PNUTS. They show that this complex associates with the splicing machinery and provides a feedback control of transcription that can be overridden by deregulated MYC.
