The peptide sequences of mouse Cx45 (Hennemann et al., 1992), mouse Cx47 (accession number AJ276435), human Cx46.6 (accession number AF014643), and mouse Cx36 (Condorelli et al., 1998) were aligned. The conserved cysteine residues are printedbold, and the core putative transmembrane domains areboxed. Identical amino acid residues between Cx47 and Cx45 or between Cx47 and Cx36 are marked with anasteriskabove or belowthe sequences, respectively. The nucleotide sequence data of mouse Cx47 are available from European Molecular Biology Laboratory under accession number AJ276435.
