Derrick Morton, PhD
Assistant Professor
University of Southern California
mortond@usc.edu

Derrick Morton’s main research objective is to understand key developmental pathways and how alterations in gene expression contribute to neurological disease. His current studies specifically exploit a Drosophila melanogaster model to examine RNA exosome-linked disease. The RNA exosome is an evolutionary-conserved riboexonuclease complex critically important for both precise processing and complete degradation of a variety of cellular RNAs. By testing the hypothesis that defects in assembly and interactions of the RNA exosome contribute to neurologic disease, we will further our knowledge of RNA exosome-linked disease and also provide invaluable insights into distinct tissue-specific consequences due to altered subunits within RNA exosome.
