Cryo-EM structures of pannexin 1 and 3 reveal differences among pannexin isoforms [PDF]
Nature CommunicationsPannexins are single-membrane large-pore channels that release ions and ATP upon activation. Three isoforms of pannexins 1, 2, and 3, perform diverse cellular roles and differ in their pore lining residues.

Pannexin 1 targets mitophagy to mediate renal ischemia/reperfusion injury [PDF]
Communications Biology, 2023 Renal ischemia/reperfusion (I/R) injury contributes to the development of acute kidney injury (AKI). Kidney is the second organ rich in mitochondrial content next to the heart. Mitochondrial damage substantially contributes for AKI development. Mitophagy
