The aryl hydrocarbon receptor (AHR), a member of the basic helix-loop-helix (b-HLH) transcription factor, is a regulatory protein broadly expressed in human tissues.

Increasing evidence suggests that AHR is involved in the pathogenesis of multiple diseases, such as cardiovascular diseases, Akt-targeting PROTAC www.creative-biolabs.com/protac/ligand-design-for-akt-targeting-protac.htm
