Xin Zhou, PhD

Dr. Zhou is using a creative protein engineering approach to break the “size barrier” of protein studies. Precise understanding of cancer protein structures can greatly facilitate the understanding of the molecular mechanisms of cancer biology and guide the design of new drugs. Recently, electron cryomicroscopy (cryo-EM) rapidly emerged as a powerful tool to deliver high-resolution protein structures. However, it remains extremely difficult to be used for proteins under a certain size (100 kDa), because most small proteins lack intrinsic structural features required for accurate structure determination. A vast number of proteins, including numerous cancer-related proteins, are smaller than 100 kDa. The successful completion of her project will result in experimental tools that are useful for the entire scientific community and will help cancer biologists to study the structures of any proteins of interest.
