The effects of Ca2+ buffers on cytosolic Ca2+ signalling
Ca2+ is one of the most important and universal intracellular signalling agents, controlling a multitude of vitally important cellular processes (Petersen & Verkhratsky 2016). The regulating cytosolic Ca2+ signals vary enormously with regard to timing, localization and spatial extent, depending on the specific cell type and the function to be controlled (Petersen & Verkhratsky, 2016). Because o...
متن کاملCa2+signalling in stomatal guard cells.
Ca(2+) is a ubiquitous second messenger in the signal transduction pathway(s) by which stomatal guard cells respond to external stimuli. Increases in guard-cell cytosolic free Ca(2+) concentration ([Ca(2+)](cyt)) have been observed in response to stimuli that cause both stomatal opening and closure. In addition, several important components of Ca(2+)-based signalling pathways have been identifi...
متن کاملCa2+ signalling: a new route to NAADP.
NAADP (nicotinic acid-adenine dinucleotide phosphate) is a derivative of NADP (nicotinamide-adenine dinucleotide phosphate), which differs by the presence of a nicotinic acid instead of a nicotinamide moiety. This small structural difference makes NAADP one of the most powerful second messengers known, able to mobilize intracellular Ca2+ in a wide range of cellular models, ranging from inverteb...
متن کاملRemodelling Ca2+ signalling systems and cardiac hypertrophy.
In cardiac cells, Ca2+ signals appear as brief transients responsible for controlling both contraction and transcription. Information may be encoded in these digital signals through changes in both frequency and shape. An increase in Ca2+ signalling contributes to a process of phenotypic remodelling during hypertrophy. The increase in Ca2+ that drives the larger contractions may be responsible ...
متن کاملAn update on nuclear calcium signalling.
Over the past 15 years or so, numerous studies have sought to characterise how nuclear calcium (Ca2+) signals are generated and reversed, and to understand how events that occur in the nucleoplasm influence cellular Ca2+ activity, and vice versa. In this Commentary, we describe mechanisms of nuclear Ca2+ signalling and discuss what is known about the origin and physiological significance of nuc...
