Molecular cloning of a partial cDNA clone encoding the C terminal region of chicken breast muscle connectin.

The cDNA sequence encoding the C terminal region of chicken skeletal muscle connectin was described. Its predicted amino acid sequence had 1,021 amino acids comprising six motif Ils (Immunoglobulin C2 domain) and five interdomains. The sequence showed 70-75% homology with that of human cardiac connectin, but 168 amino acids including one motif II were missing in chicken skeletal muscle connectin. The C terminal sequence of chicken skeletal muscle connectin reported by the previous work (Maruyama et al., 1994) was erroneous due to the accidental ligation of the cDNA clone encoding a N terminal region of connectin with a partial porin cDNA clone.
