An innexin is a member of a class of proteins which is used to create gap junctions in invertebrates. The innexin protein and its vertebrate homologue pannexin1 have 4 transmembrane spanning units and, like the vertebrate connexin gap junction protein, 6 innexin (or pannexin 1) subunits together form a channel, an "innexon," in the plasma membrane. Two innexons in apposed plasma membranes can form a gap junction.
