About EGM
The "Microbial Gene Expression" unit (EGM; UMR8261 CNRS, Université Paris Cité), was founded by Marianne Grunberg-Manago in the early 60s. We perform fundamental research on the control of gene expression inmicroorganisms (E. coli, B. subtilis, Synechocystis and S. cerevisiae) using genetic, biochemical and structural approaches. RNA, in all its forms, plays a central role in our work, which focuses on key steps in the control of gene expression: gene transcription, mRNA stability and translatability. The unit currently employs 35 people in 5 scientifically autonomous teams.
1. RNA MAturation and Decay (headed by Ciarán Condon)
2. Biogenesis, architecture and interactions of RNAs (Headed by Carine Tisné)
3. RNA control of gene expression (Headed by Maude Guillier)
4. Physiology and regulation of protein synthesis (Headed by Grégory Boël)
5. Transcriptional and post-transcriptional controls of gene expression (Headed by Harald Putzer)
