BU SBRP researchers Mark Hahn (project 5) and David Sherr (project 4) have a new publication titled "Repression of aryl hydrocarbon receptor (AHR) signaling by AHR repressor (AHRR): Role of DNA binding and competition for ARNT" in the journal Molecular Pharmacology. In this paper the authors propose a mechanism for aryl hydrocarbon receptor signaling through protein-protein interactions.
