Regulation of Trafficking and Functions of Voltage-Gated Sodium and Calcium Channels; Identification of Novel Protein Regulators of Ion channels; Approaches to Targeting the Ion Channel Complexes in Neuropathic Pain and Neurodegenerative Diseases; Discovery of Novel Biologics and Small Molecules Targeting Pain and Neurodegenerative Diseases
The focus of my laboratory’s’ research is to understand how ion channels, specifically, voltage-gated calcium and sodium channels, are regulated by novel protein interactions. Recent studies in my laboratory have focused on targeting protein-protein interactions with biologics (peptide aptamers) and small molecules; testing the activity of these novel chemical entities in biochemical and immunofluorescent-based assays of trafficking; examining their protein interaction signatures; testing them with whole cell voltage-clamp electrophysiology and voltage- and calcium sensitive fluorescence-based imaging. Regulating these protein networks to modulate the activity of ion channels in neurodegenerative diseases (Chronic Pain, Migraine, and Neurofibromatosis) is a key focus of the laboratory.
