Endoplasmic and sarcoplasmic reticulum in the heart
Trends in Cell Biology, 2009The concept of the presence of sarcoplasmic reticulum (SR) membrane in the heart is widely accepted and has been considered merely to be a different name for the endoplasmic reticulum (ER) in muscle tissues. Cardiac SR membranes are specialized in the regulation of Ca(2+) transport and control of excitation-contraction coupling.

The sarcoplasmic reticulum: A comparative study
Comparative Biochemistry and Physiology Part A: Physiology, 1985The diversity of cellular membrane structures associated with regulation of intracellular calcium level is described in several different groups of organisms and cells. All the instances reported refer to cellular processes related to movement, in which calcium ion acts as trigger and/or modulator.

Sarcoplasmic reticulum and membrane currents.
Novartis Foundation symposium, 2002Local and global Ca2+ signals from voltage-dependent Ca2+ channels (VDCCs) and ryanodine-sensitive Ca2+ release (RyRs) channels in the sarcoplasmic reticulum (SR) encode information to different Ca2+-sensitive targets including the large- (BK) and small-conductance (SK) Ca2+-activated K+ channels in the surface membrane.

The Development of Sarcoplasmic Reticulum Membranes
Annual Review of Physiology, 1982Growth-control mechanisms are probably very complicated. Nevertheless, there is a strong drive to devise simple models. The dilemma is that the models may be misleading. Probably each of us is willing to tolerate being misled a little because we hope that our preferred model will be of more help than hindrance. Unfortunately, there is no way to know in

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1978
Abstract 1. 1. Sarcoplasmic reticulum vesicles were prepared from the flight-muscles of Locusta migratoria by cell fractionation and sucrose gradient fractionation. 2. 2. Properties of the sarcoplasmic reticulum ATPase were studied. 3. 3. The ATPase was strongly dependent on Ca 2+ , Mg 2+ and K + . 4. 4.
