Abstract: The natural flight response in shrimp is powered by rapid contractions of the abdominal muscle fibres to propel themselves backwards away from perceived danger. This muscle contraction is dependent on repetitive depolarization of muscle plasma…

Abstract: Ca2+-induced Ca2+ release (CICR), the process whereby a small influx of Ca2+ across the sarcolemma triggers a significantly larger Ca2+ release from the sarcoplasmic reticulum (SR), is at the heart of efficient cardiac excitation–contraction coupling…

Abstract: It is well-established that extracellular potassium (Ko+) accumulation reduces muscle fiber excitability, however the effects of Ko+ on the excitation-contraction coupling (ECC) pathway are less understood. In vivo and in vitro studies following fatiguing stimulation…

Abstract: STAC3 is a soluble protein essential for skeletal muscle excitation-contraction (EC) coupling. Through its tandem SH3 domains, it interacts with the cytosolic II-III loop of the skeletal muscle voltage-gated calcium channel. STAC3 is the target…

Abstract: Cardiac sodium (Na+) potassium ATPase (NaK) pumps, neuronal sodium channels (INa), and sodium calcium (Ca2+) exchangers (NCX1) may co-localize to form a Na+ microdomain. It remains controversial as to whether neuronal INa contributes to local…

Abstract: AIMS β-Adrenergic receptors (βARs) play pivotal roles in regulating cardiac excitation-contraction (E-C) coupling. Global signaling of β1ARs upregulates both the influx of Ca2+ through sarcolemmal L-type Ca2+ channels (LCCs) and the release of Ca2+ from…

Abstract: The intracellular calcium handling system of cardiomyocytes is responsible for controlling excitation-contraction coupling (ECC) and has been linked to pro-arrhythmogenic cellular phenomena in conditions such as heart failure (HF). SERCA2a, responsible for intracellular uptake, is…

Abstract: Skeletal and cardiac muscle excitation–contraction coupling commences with Nav1.4/Nav1.5-mediated, surface and transverse (T-) tubular, action potential generation. This initiates feedforward, allosteric or Ca2+-mediated, T-sarcoplasmic reticular (SR) junctional, voltage sensor-Cav1.1/Cav1.2 and ryanodine receptor-RyR1/RyR2 interaction. We review…
