Fig. 7: Schematic of PANX isoforms.
From: Cryo-EM structures of pannexin 1 and 3 reveal differences among pannexin isoforms

A schematic of the three PANX isoforms displaying differences in their structural organization. The residues lining the pore at the extracellular domain are distinct among the three isoforms. The distance between residues at the constriction point are indicated.
