The general theme of the lab is understanding the molecular basis of Alzheimer’s disease (AD) and related dementias and exploring new strategies for therapeutic intervention. One focus of the lab has been on gamma-secretase, a membrane-embedded protease that produces the amyloid beta-peptide (A-beta) implicated in the pathogenesis of AD. This protease also plays a variety of critical roles in biology. Small organic inhibitors were developed and used as tools to characterize and identify gamma-secretase. The lab discovered that gamma-secretase is a complex of four different integral membrane proteins, with presenilin as the catalytic component of an unusual aspartyl protease. Purification of the complex has allowed biochemical and structural characterization and a clearer understanding of how inhibitors and modulators interact with the enzyme. Ongoing projects include functional studies of the gamma-secretase complex, how these functions are altered by AD-causing presenilin mutations, and how these alterations may trigger AD pathogenesis.
