Chains	Accession	Name	Description	Comments	Source
A [auth D], B [auth A], C [auth B], D [auth C], E, A [auth D], B [auth A], C [auth B], D [auth C], E, F, G, H, I, J	PF00029	Connexin (Connexin)	Connexin	Connexin proteins form gap-junctions between cells. They carry four transmembrane regions, hence why this family now includes Connexin_CCC, which represented the second pair of TMs.	Domain
