Protein Family Annotation Pfam Database Homepage

Chains	Accession	Name	Description	Comments	Source
A, B, C, D, E A, B, C, D, E, F	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
