Activator binding alters Mediator structure, yet the functional consequences of such structural shifts remain unknown. The p53 C terminus and its activation domain interact with different Mediator subunits, and we find that each interaction differentially affects Mediator structure; strikingly, distinct p53-Mediator structures differentially affect Pol II activity. Only the p53 activation domain induces the formation of a large pocket domain at the Mediator-Pol II interaction site, and this correlates with activation of stalled Pol II to a productively elongating state. Moreover, we define a Mediator requirement for TFIIH-dependent Pol II C-terminal domain phosphorylation and identify substantial differences in Pol II C-terminal domain processing that correspond to distinct p53-Mediator structural states. Our results define a fundamental mechanism by which p53 activates transcription and suggest that Mediator structural shifts trigger activation of stalled Pol II complexes."}],"oa_version":"None","main_file_link":[{"open_access":"1","url":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2932482/"}],"_id":"598","author":[{"last_name":"Meyer","full_name":"Meyer, Krista","first_name":"Krista"},{"full_name":"Lin, Shih","first_name":"Shih","last_name":"Lin"},{"id":"2CB9DFE2-F248-11E8-B48F-1D18A9856A87","last_name":"Bernecky","orcid":"0000-0003-0893-7036","first_name":"Carrie A","full_name":"Bernecky, Carrie A"},{"first_name":"Yuefeng","full_name":"Gao, Yuefeng","last_name":"Gao"},{"last_name":"Taatjes","full_name":"Taatjes, Dylan","first_name":"Dylan"}],"doi":"10.1038/nsmb.1816","title":"P53 activates transcription by directing structural shifts in Mediator","citation":{"ista":"Meyer K, Lin S, Bernecky C, Gao Y, Taatjes D. 2010.
