Revised Manuscript Received December 30, 1986 abstract: Target inactivation analysis was carried out on the ryanodine receptor. This receptor recently has been implicated as the channel involved in the calcium releaseprocess in excitation-contraction coupling and was localized to the junctional terminal cisternae of sarcoplasmic reticulum from skeletal muscle [Fleischer, S., Ogunbunmi, E. M., Dixon, M. C., & Fleer, E. A. M.(1985) Proc. Natl. Acad. Sci. USA 82, 7256-7259], Irradiation of the junctional terminal cisternae resulted in an exponential decrease in ryanodine bindingwith radiation dose, thereby consistent with target theory. The target molecular weight was found to be 138 000±21 000, ie, smaller than the polypeptidethat binds ryanodine. The calcium pump protein in the same membrane preparation served as an internal control to validate the methodology.
