Research Interests

My dissertation is focused on elucidating the cellular and molecular mechanism of regulatory pathways governing deltaF508-CFTR. The deltaF508 mutation is the most common mutation among CF (Cystic Fibrosis) patients. Approximately 90% of the total patient population carry one copy and 50% are homozygous. The mutation is characterized by a misfolded CFTR protein which is degraded early on by the proteasome. My particular interest lies with the CAL (CFTR-Associated Ligand) protein, a PDZ domain containing protein that is critical for WT-CFTR trafficking and may play an important role in deltaF508-CFTR regulation. Data has shown that knockdown of the CAL protein can alter trafficking and maturation of deltaF508-CFTR. Our goal is to investigate the effects of CAL on deltaF508-CFTR, and elucidate the mechanism by which it regulated deltaF508-CFTR surface expression.
