title: Endoplasmic reticulum in the heart, a forgotten organelle?
abstract: Our hypothesis is that sarcoplasmic and endoplasmic reticulum Ca2+ stores may be functionally distinct compartments in cardiomyocytes. Sarcoplasmic reticulum Ca2+ store is responsible for control of excitation-contraction coupling whereas endoplasmic reticulum compartment may provide Ca2+ for housekeeping and transcriptional functions.
