Snf1 cooperates with the CWI MAPK pathway to mediate the degradation of Med13 following oxidative stress
Willis et al.This article explores the response of eukaryotic cells to environmental stress, highlighting the role of the conserved cyclin C-Cdk8 kinase in determining pro-survival or pro-death programs.
