Professor Cho Yoon-jea is an authority in the field of structural biology who has
greatly contributed to the understanding of the causes of cancer and the secret of
the four phases of life by investigating a mechanism to maintain stability of
necessary genes for the proper growth of organisms.

Professor Cho investigated a mechanism to recognize damaged DNA and heal genes by molecular biological testing and investigating the three-dimensional structure of a protein and protein complex (Mus81-Emel) that suppresses cancer and other tumors. He suggested the potential for new anti-cancer drugs that control gene stability through an essential understanding of signal conditioning mechanisms and recognition of molecular interaction on protein networks.

Professor Cho also revealed the interaction mechanism of geminin, a protein which can block the growth of cancer cells so that gene replication proceeds according to cell cycles for the first time, a groundbreaking achievement in defeating cancer.

Professor Cho's major papers have been widely cited by many researchers in chemistry and biophysics as well as biology, including Science 2, issue 178, and Nature issue 109, and he is considered one of the top structural biologists in the world. Anti-cancer drugs based on Professor Cho ideas are in development and the results should be evident in the near future.
