Research Interests
I have a strong interest in understanding the molecular pathways that underlie developmental processes, with a special focus on the epigenetic regulation of intercellular communication. During my graduate training with Drs. Joan and Ron Conaway at the Stowers Institute, I defined the functions of Neurl1, a mouse ortholog of Drosophila Neur, as an E3 ubiquitin ligase that monoubiquitinates Jagged1, but not other mammalian Notch ligands. My findings provided new insights into the functions of Neurl1 at the plasma membrane in regulating the signaling activity of Jagged1.
As a postdoctoral fellow and now an Assistant Professor in Sharon Dent’s lab at the M.D. Anderson Cancer Center, I have focused on defining the functions of USP22, a component of the SAGA complex linked to human disease and cancer, combining mouse genetics with genome-wide profiling of chromatin states and gene expression. USP22 is a deubiquitinase that targets histone H2B (H2Bub1) as well as non-histone substrates. To define the functions of this enzyme in vivo, I have created both null mutations in USP22 and mutations in the catalytic site in mice. My studies have revealed an unexpected function for USP22 in the development of placenta vasculature. As the development of the placenta shares many of the same processes involved in cancer formation or progression, my findings will provide new insights as to how overexpression of USP22 contributes to aggressive, therapy-resistant cancers.
