STAT5 is a critical transcription factor that is required for proper lymphocyte development. For example, STAT5 is essential for CD8 T lineage commitment, regulatory T cell (Treg) development, B cell development and lymphocyte transformation. Active phosphorylated STAT5 can bind to target genes to either activate or repress transcription, however, the mechanism by which this occurs remains unclear. We hypothesize that STAT5 represses target genes via selective interactions with co-repressors, NCOR1 and NCOR2, and induces transcription via interactions with co-activators, CREBBP and EP300. The goal of my thesis is to characterize the role of these co-repressors and co-activators in lymphocyte development (B and T cell) and transformation (B cell acute lymphoblastic leukemia).
