Parameswaran lab

Research focus of Parameswaran’s lab is directed towards understanding the cellular and biochemical mechanisms involved in the pathogenesis of inflammatory diseases. The emphasis is on two different protein families (arrestins and G-protein coupled receptor kinases, GRKs) in the context of how these proteins regulate signal transduction in innate immune cells (eg. macrophages) that is especially relevant in inflammation and disease. Arrestins are scaffolding proteins that can bind to receptors as well as signaling proteins and have a broad role in cell signaling. GRKs are serine/threonine kinases that can bind to and phosphorylate receptors and other intracellular substrates. Recent studies indicate that members of these two protein families have important functions in innate immune cells. Research in Parameswaran’s lab is currently focused towards understanding the biochemical and signaling mechanisms of arrestins and GRKs in immune cell types such as macrophages. How these functions of arrestins and GRKs are translated in disease pathogenesis is also another important area that is being pursued.
