UniProt ID Q9NTQ9
Protein name Gap junction beta-4 protein (Connexin-30.3) (Cx30.3)
Protein function Structural component of gap junctions (By similarity). Gap junctions are dodecameric channels that connect the cytoplasm of adjoining cells. They are formed by the docking of two hexameric hemichannels, one from each cell membrane (By similarity
