Fig. 4: Electrostatic properties comparison of pannexin channels.
From: Cryo-EM structure of human heptameric pannexin 2 channel
a The interior surface of Panx2, full-length Panx1 and Panx1-ΔCT colored according to the electrostatic surface potential from −5 to +5 kT e–1 (red to blue). The cross-section is colored gray. Surface representation of the Panx2 (b), full-length Panx1 (c) and Panx1-ΔCT (d) structures colored by electrostatic surface potential. The side view, top view and bottom view of all structures are presented. R89 of Panx2, E414 and S424 of full-length Panx1, W74 of Panx1-ΔCT are indicated by dashed lines.
