Dr. Cianfrocco [HHMI Fellow] studies proteins called dynactin and dynein that function to transport organelles within the cell, a process that is particularly important during cell division. He aims to elucidate the structural basis for dynactin's ability to regulate dynein activity. Since many viruses, including cancer-causing oncoviruses, require dynein to be transported from the cell membrane to the nucleus for genome replication, understanding the molecular details of dynein-dynactin function may provide novel targets for cancer therapies.
