Biography and Research Information

OverviewAI-generated summary

Sibes Bera's research investigates the molecular mechanisms of retroviral integration, focusing on the structure and function of intasomes. Bera has published on the cryo-electron microscopy structure of the Rous sarcoma virus octameric cleaved synaptic complex intasome. Further work has explored molecular determinants for Rous sarcoma virus intasome assemblies involved in retroviral integration, and the delineation of a novel assembly intermediate in the retroviral integration pathway. Bera's work also includes the improved purification of human granzyme A/B and granulysin using a mammalian expression system. Bera has an h-index of 15, with 37 total publications and 734 total citations.
