Environmental cues regulate many biological processes, controlling pathways used by cells to respond to 

changing conditions. Such regulation often utilizes natural allosteric “switches” in the form of protein 

domains that use internally-bound ligands to convert environmentally-triggered changes into altered 
interactions with other signaling partners. Several families of these domains have evolved with 

remarkable diversity in the stimuli they sense and outputs that they control. Using the unparalleled 

flexibility of NMR spectroscopy coupled with other biophysical, biochemical and chemical approaches, 

the Gardner laboratory studies the sensory mechanisms of such domains – obtaining insights into their 

natural control and laying the foundations for applications where artificial triggers can be applied. 
Recent work within the group has focused on classes of Per-ARNT-Sim (PAS) domain proteins, ranging 

from bacterial blue light photosensors to mammalian hypoxia sensors. While these systems control 

diverse biology in different settings, they share common signaling mechanisms triggered by small 

organic cofactors and ligands. Mechanistic findings from these studies have both advanced our 

understanding of biochemical regulation and established both protein- and small molecule-based tools 

for basic research and applied uses.
