PICking apart Pol II initiation

The recent mapping and modeling of protein-protein interfaces between general transcription factors TFIIE, TFIIH and Pol II have provided new insights into TFIIH-mediated melting of the transcription start site to form an open Pol II preinitiation complex and the stabilization of the complex by TFIIE, leading to a new mechanistic model for open-complex formation.
