Detection and localization of triadin in rat ventricular muscle
Dyads (transverse tubule—junctional sarcoplasmic reticulum complexes) were enriched from rat ventricle microsomes by continuous sucrose gradients. The major vesicle peak at 36% sucrose contained up to 90% of t...

Map** of the calpain proteolysis products of the junctional foot protein of the skeletal muscle triad junction
The Ca2+ activated neutral protease calpain II in a concentration-dependent manner sequentially degrades the Junctional foot protein (JFP) of rabbit skeletal muscle triad junctions in either the triad membrane or...

Identification of a new subpopulation of triad junctions isolated from skeletal muscle; Morphological correlations with intact muscle
It has been previously recognized that a number of protocols may cause breakage of the triad junction and separation of the constituent organelles of skeletal muscle. We now describe a fraction of triad juncti...

Molecular interactions of the junctional foot protein and dihydropyridine receptor in skeletal muscle triads
Isolated triadic proteins were employed to investigate the molecular architecture of the triad junction in skeletal muscle. Immunoaffinity-purified junctional foot protein (JFP), glyceraldehyde 3-phosphate deh...

Proteins of the Triad Junction of Skeletal Muscle
The basic mechanism of excitation-contraction coupling in skeletal muscle is still not understood despite many years of active research on both the physiology and the biochemistry of the process. Several years...

Determinants of triad junction reformation: Identification and isolation of an endogenous promotor for junction reformation in sketal muscle
The junction of isolated triads can be mechanically broken by passage through a French press and subsequently reformed by incubation of the isolated organelles with certain salts of weak acids (e.g., K cacodyl...

Ion-induced release of calcium from isolated sarcoplasmic reticulum
Choline Cl addition to either longitudinal reticulum or terminal cisternae of skeletal muscle sarcoplasmic reticulum caused release of Ca2+ which had previously accumulated in the presence of ATP. However the ext...
