Abstract
The protein oligomer forming the gap junction channel has been analysed in two Ca2+-sensitive states by electron microscopy of membranes in frozen aqueous solutions. Switching between states occurs by a small cooperative rearrangement involving tilting of the subunits, which may be responsible for the effect of Ca2+ on channel permeability in vivo.Entities:
