How potassium ion channels and transport proteins interact
Ion Channel Transporter Interactions
This project explores how potassium channels work together with transport proteins in cells to help find new medicines for people with conditions like epilepsy, certain heart rhythm problems, ataxia, and related metabolic or digestive disorders.

What this research studies
Researchers are studying specific potassium channel families (Kv1 and Kv7) and how they form physical complexes with sodium-coupled transporters, a concept the team calls "chansporter" complexes. They will use laboratory experiments, molecular and cellular assays, and chemical screening to find small molecules (including plant-derived compounds) that change channel or complex behavior. The team builds on prior discoveries of chansporter interactions and novel channel modulators to map how these complexes influence cell signaling. Most work is lab-based and aims to create leads that could later move into animal studies and, eventually, clinical testing.
Who could benefit from this research
Good fit: People with epilepsy, genetic forms of ataxia, inherited cardiac rhythm disorders, or conditions linked in the summary like achlorhydria or thyroid-related problems could be future candidates for trials based on this research.
Not a fit: Patients needing immediate treatment or whose illnesses are unrelated to potassium-channel or transporter dysfunction are unlikely to receive direct benefit from this basic laboratory research right away.
Why it matters
Potential benefit: If successful, this work could identify new drug targets or small molecules that lead to treatments for epilepsy, inherited ataxias, certain arrhythmias, and some metabolic or digestive conditions.
How similar studies have performed: Drugs that target potassium channels have been developed before and the team has reported novel 'chansporter' interactions and modulators, but turning these basic discoveries into new approved therapies remains at an early stage.
