connexons

con·nex·ons

(kŏ-neks'ŏnz), Complex protein assemblies that traverse the lipid bilayer of the plasma membrane and form a continuous channel with a pore diameter of approximately 1.5 nm; a pair of connexons from two adjacent cells join to form a gap junction that bridges the 2-4-nm gap between the cells, resulting in both electrical and metabolic couplings; one type of connexons makes up the gap junction in the heart and may coordinate the beating of all muscle cells in one section of the heart.
