Calcium Signals from the Vacuole
The vacuole is by far the largest intracellular Ca(2+) store in most plant cells. Here, the current knowledge about the molecular mechanisms of vacuolar Ca(2+) release and Ca(2+) uptake is summarized, and how different vacuolar Ca(2+) channels and Ca(2+) pumps may contribute to Ca(2+) signaling in plant cells is discussed. To provide a phylogenetic perspective, the distribution of potential vac...
متن کاملCalcium signals from outside
alcium just got a promotion. Findings by Caroppo et al. (page 111) reveal that in addition to its many roles inside the cell, Ca 2 ϩ has a distinct extracellular purpose: it acts via a Ca 2 ϩ receptor (CaR) to regulate the function of gastric epithelial cells. It has been known for some time that extracellular Ca 2 ϩ can be sensed by the CaR. The team noted that a Ca 2 ϩ gradient was generated ...
متن کاملoocyte activation: the impact of calcium signals on fertilization
fertilization is triggered by changes in intracellular calcium concentration. in mammals, these transients in ooplasmic calcium concentration take the form of repetitive spikes, so called calcium oscillations (ca2+-oscillations). these oscillations are important for relieve of meiotic arrest and to induce all the other events of oocyte activation. although a surface mediated way of oocyte activ...

متن کاملSource of nuclear calcium signals.
Transient increases of Ca2+ concentration in the nucleus regulate gene expression and other nuclear processes. We investigated whether nuclear Ca2+ signals could be regulated independently of the cytoplasm or were controlled by cytoplasmic Ca2+ signals. A fluorescent Ca2+ indicator that is targeted to the nucleus was synthesized by coupling a nuclear localization peptide to Calcium Green dextra...
