In 1954, Reiji Natori proposed the existence of an elastic structure in muscle fiber to account for the return to the resting state when muscles are stretched and then released. In 1977, Koscak Maruyama and coworkers isolated an elastic protein from muscle fiber that they called connectin. Two years later, Kuan Wang and coworkers identified a doublet band on electrophoresis gel corresponding to a high molecular weight, elastic protein that they named titin.
