Structure and Function of Proteins with Special Reference to Insulin and Insulin-like Growth FactorsCrystal structures of insulin are now appreciated to represent inactive conformers of the hormone. One area of our research is to deduce features of insulin's receptor-active structure through mutidimensional NMR studies of paradoxical insulin analogs.\r\n\r\n
\r\nThe second area of our research is mapping the contact points of insulin and its receptor by the use of novel photo-crosslinking insulin analogs.\r\n

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.
Dr.Katsoyannis is not currently required to report Industry relationships.
Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website at http://icahn.mssm.edu/about-us/services-and-resources/faculty-resources/handbooks-and-policies/faculty-handbook. Patients may wish to ask their physician about the activities they perform for companies.
