The discovery and analysis of these mechanisms was the key to understanding conformation changes in serine protease inhibitors, also known as serpins, mutations of which are an important cause of several diseases, including emphysema and certain types of inherited mental illness. LeskвЂ™s work also involves the detailed comparison of proteins in different structural states as a means for understanding the mechanisms that enable the proteins to change conformation, both as part of their normal activity and in disease. вЂњHumanization of these antibodies is the formation of hybrid molecules that are more human than rat, but that retain the therapeutic activity while reducing the patientвЂ™s immune response.вЂќ Waldmann that rats can raise antibodies against human cancers, but that the rat antibodies lead to immune responses, similar to allergies, in human patients,вЂќ Lesk explains. вЂњThis approach to cancer therapy is based on the observation of H. This work has supported the вЂњhumanizationвЂќ of antibodies for therapy in the treatment of cancer. They discovered the вЂњcanonical-structure modelвЂќ for the conformation of the complementarity-determining regions of antibodies, and they applied this model to the analysis of antibody-germ-line genes, including the prediction of the structure of the corresponding proteins. Lesk and Chothia also studied the conformations of antigen-binding sites of immunoglobulins. This discovery has provided the quantitative basis for the most successful and widely used method of structure prediction, known as homology modelling. He and Cyrus Chothia, working at the Medical Research Council (UK) Laboratory of Molecular Biology in Cambridge, United Kingdom, discovered the relationship between changes in amino-acid sequence and changes in protein structure by analyzing the mechanism of evolution in protein families.

Lesk has made significant contributions to the study of protein evolution. He also received a master's degree from the University of Cambridge in the United Kingdom in 1999. He received his doctoral degree from Princeton University in 1966. Lesk received a bachelor's degree, magna cum laude, from Harvard University in 1961. 3 Schematic diagrams of protein structures.
