Dr. Nickerson’s research is focused on understanding the molecular mechanisms controlling Na+ and K+ transport in the distal nephron. He uses electrophysiology, mouse model systems, and molecular biological techniques to study ion channel structure/function. His recent studies established that proteolytic cleavage of epithelial Na+ channel (ENaC) subunits is necessary for appropriate channel activation in vivo. His current project is aimed at exploring the role of BK channel accessory subunits in renal K+ secretion, as well as the cell-specific role of aldosterone signaling in the process.
