Targeting of ion channels and transporters at the sarcoplasmic reticulum and T-tubule junction membrane of the heart ventricles. The flux of calcium ions is facilitated by ankyrin B complex from the sarcoplasmic reticulum via inositol triphosphate receptors (InsP3R) and across the plasma membrane via the sodium calcium exchangers (NCX) and sodium potassium adenosine triphosphatase (NKA)
