Pannexin 1 (PANX1) is a membrane channel mediating release of signaling molecules to the extracellular space. PANX1 can be activated by GPCRs. Here, the authors elucidate a non-canonical channel activation pathway by α1-adrenergic receptor that involves HDAC6- mediated lysine deacetylation of PANX1.
