Analysis of E2F1 by clAP1

2017

The cellular inhibitor of Apoptosis 1 (cIAP1) behaves as an E3 ubiquitin ligase and has oncogenic properties. Previously, our team has shown that cIAP1 can regulate the E2F1 transcription factor activity. My research project has been focused on deepening our current knowledge on this interaction. Firstly, we characterized the E2F1-cIAP1 interaction, then we analyzed the regulation of E2F1 by cIAP1 and finally assessed the importance of the cIAP1-E2F1 interaction for the oncogenic properties of cIAP1. I have demonstrated a interaction of E2F1 with the hydrophobic pocket of the BIR3 domain of cIAP1. Moreover, I highlighted that the alpha 1 helix of the BIR3 domain is mandatory for the stabili…
