Pannexin2 oligomers localize in the membranes of endosomal vesicles in mammalian cells while Pannexin1 channels traffic to the plasma membrane
Pannexin2 (Panx2) is the largest of three members of the pannexin proteins. Pannexins are
topologically related to connexins and innexins, but serve different functional roles than …
