How can #replication initiator ORC load replicative #helicases in condensed chromatin?
Structural and biochemical work by Franziska Bleichert and colleagues shows how ORCA recruits ORC to certain #histone marks, and also reorganizes local #chromatin structure

Hello #ScienceMastodon Twitter refugees
#introduction I am a 🇫🇷 molecular & structural biologist working at the CNRS. I study the molecular mechanisms that control human gene expression focusing on #transcription factors & the Pol II machinery
Expect to see here a lot of info on #generegulation, #enhancers, #histone modifications & structural insights into the eukaryotic Transcription Initiation machinery. #CryoEM
I will also highlight #womeninscience to give them the visibility they deserve
