Published: 2 September 2022
...Ahmed Badr; Minna Hassinen; Matti Vornanen ABSTRACT The spatial pattern of electrical activation is crucial for a full understanding of fish heart function. However, it remains unclear whether there is regional variation in action potential (AP) morphologies and underlying ion currents. Because...

... and Kir3.4 channels ( Hibino et al., 2010 ). The molecular basis of ACh-activated inward rectifiers of the fish heart is not yet known, but because of the whole genome duplication in the teleost fishes ( Jaillon et al., 2004 ), the diversity of this current system may be greater in fishes than mammals...

... that they are intimately involved in thermal tolerance and temperature acclimation of cardiac function. Species-specific differences in channel composition and subunit assemblies may provide different thermal dependencies to electrical excitability of the fish heart. For example, the inward rectifier potassium current, I...

...Hanna Korajoki; Matti Vornanen SUMMARY Calsequestrin (CASQ) is the main Ca 2+ binding protein within the sarcoplasmic reticulum (SR) of the vertebrate heart. The contribution of SR Ca 2+ stores to contractile activation is larger in atrial than ventricular muscle, and in ectothermic fish hearts...
