Cancer Research Focus
The products of the Recombination Activating Genes (RAG) initiate DNA double-strand breaks during V(D)J recombination, which is the process that is responsible for assembling immunoglobulin and T cell receptor genes in lymphocytes. While essential for normal development of adaptive immunity, this process is not always benign, as certain types of leukemia and lymphoma harbor aberrant DNA rearrangements that can be traced to mistakes during V(D)J recombination. A major focus of research in my laboratory to understand the regulatory mechanisms that constrain RAG activity and guide the appropriate repair of the RAG-induced DNA breaks to prevent genome instability and cancer.

Research Focus
I am generally interested in mechanisms of immune repertoire diversification. My research program is currently focused on studying various aspects of V(D)J recombination, the process by which immunoglobulin and T cell receptor genes are assembled during lymphocyte development. V(D)J recombination is initiated by the RAG1 and RAG2 proteins, which together introduce DNA breaks in the antigen receptor loci, which are subsequently repaired by components of the non-homologous DNA end-joining (NHEJ) repair pathway (Fig. 1). The laboratory has two major ongoing projects. The first project is broadly focused on how proteins that associated with the full-length RAG1 regulate V(D)J recombination by facilitating DNA end-joining or the timely degradation of RAG1. The second project involves determining whether enforced expression of catalytically inactive RAG1 in mice can impair secondary V(D)J recombination events triggered by engagement of self-antigen (receptor editing) or in response to immunization (receptor revision), and whether defects in these processes increase susceptibility to malignancy or autoimmune disease. These research projects are or have been supported by both intramural and extramural grants, including grants awarded by the National Institutes of Health and the American Cancer Society.
