A partial connectin cDNA encoding a novel type of RSP motifs isolated from chicken embryonic skeletal muscle.
A partial cDNA encoding 811 amino acids of connectin (titin), a giant elastic protein of muscle (3,000 kDa), was cloned from a chicken embryonic skeletal muscle cDNA library using antibodies to muscle connectin. The encoded product was the C terminal segment of connectin. The predicted sequences consisted of 5 type II motifs (immunoglobulin C2 type) separated by 5 interdomain insertions. One interdomain insertion had significant homology (RSP) to KSP repeats found in human cardiac C-terminal connectin and another had a high sequence homology to porin (67.7%; 31 amino acids).
