The research in our laboratory focuses on epigenetics and RNA processing. In particular, we are interested in the roles of small ribonucleoproteins (RNPs) and histone post-translational modifications in the regulation of eukaryotic gene expression. There are two main projects in the lab. (1) We have created a comprehensive genetic platform for histone gene replacement that — for the first time in any multicellular eukaryote — allows us to directly determine the extent to which histone post-translational modifications contribute to cell growth and development. (2) We study an RNP assembly factor (called Survival Motor Neuron, SMN) and its role in neuromuscular development and a genetic disease called Spinal Muscular Atrophy (SMA). Current work is aimed at a molecular understanding of SMN’s function in spliceosomal snRNP assembly and its dysfunction in SMA pathophysiology.
