Changes in conformation underlie the fundamental function of all proteins. Innovative therapeutics such as Gleevec function by holding its target protein in a non-active conformation that is unique across the kinome. Direct detection of protein conformational change offers a significant opportunity for the design of structurally-specific therapeutics. We have adapted Second Harmonic Generation (SHG), an optical technique to a discovery format to detect conformational change in a series of protein standards which represent a range of movement (rigid to floppy.) We will describe our use of SHG to screen and identify inhibitors of spermine-induced conformation change in monomeric alpha-synuclein, a key protein implicated in the etiology of Parkinson’s disease. In addition, we will introduce SHG as a means of uniquely identifying conformation-specific changes in kinases.
