Given that histone accumulation is toxic to cells and leads to genomic instability – which is a hallmark of all human cancers – understanding the mechanisms of histone homeostasis is critical. The overall goal of my research program is to elucidate the human histone homeostasis pathways, with a particular focus on histone degradation and the protein interaction networks of histone complexes. Over the next few years, my laboratory will conduct comprehensive genomic and proteomic screens to illuminate proteins involved in maintaining and degrading histone complexes. This work will lay the foundation for future projects that delve deeper into the mechanistic aspects of histone life cycle in healthy and cancerous cells. Our ulitmate goal is to solve cryo-EM structures of histone degradation complexes providing a new framework for developing cancer therapeutics.
