Gap junction
text:
Gap junctions are membrane channels between adjacent cells that allow the direct exchange of cytoplasmic substances. Substances exchanged include small molecules, substrates, and metabolites. Gap junctions were first described as close appositions as other tight junctions, but following electron microscopy studies in 1967, they were renamed gap junctions to distinguish them from tight junctions. They bridge a 2-4 nm gap between cell membranes. Gap junctions use protein complexes known as connexo
