Calcium release during skeletal muscle excitation-contraction (EC) coupling occurs at the junctions between the sarcoplasmic reticulum (SR) and either the plasma membrane or the transverse (T) tubules. ... (2) a C-terminal signal sequence is responsible for the targeting of the a1S into the junctional T-tubule membrane;

In this sequence of the normal heart, we have reviewed the process of excitation contraction coupling. As will be discussed subsequently, this process of excitation contraction coupling becomes dysregulated in cardiac hypertrophy and cardiac failure.

We have used an intact alpha(1S) subunit with scrambled sequence in this region of the II-III loop (alpha(1S)-scr) to test the importance of residues 681-690 and the basic motif for skeletal-type excitation-contraction (EC) coupling and retrograde signaling in vivo.
