regulation of cytosolic calcium ion concentration
Definition
Target type: biologicalprocess
Any process involved in the maintenance of an internal steady state of calcium ions within the cytosol of a cell or between the cytosol and its surroundings. [GOC:ai, GOC:mah, GOC:rph]
The regulation of cytosolic calcium ion concentration is a critical process in all eukaryotic cells, playing a vital role in a wide range of cellular functions, including muscle contraction, neurotransmission, fertilization, and apoptosis. The precise control of intracellular calcium levels is achieved through a complex interplay of influx, efflux, and sequestration mechanisms.
**Influx:**
* **Voltage-gated calcium channels:** These transmembrane proteins open in response to membrane depolarization, allowing calcium ions to enter the cytosol from the extracellular space.
* **Ligand-gated calcium channels:** These channels are activated by the binding of specific ligands, such as neurotransmitters or hormones.
* **Store-operated calcium channels (SOCCs):** These channels open when the endoplasmic reticulum (ER) calcium stores are depleted, allowing calcium influx from the extracellular space to replenish the stores.
**Efflux:**
* **Plasma membrane calcium ATPases (PMCAs):** These pumps actively transport calcium ions out of the cytosol against their concentration gradient, using energy derived from ATP hydrolysis.
* **Sodium-calcium exchangers (NCXs):** These exchangers use the electrochemical gradient of sodium ions to drive the efflux of calcium ions from the cytosol.
**Sequestration:**
* **Sarcoplasmic reticulum (SR) calcium ATPases (SERCAs):** These pumps actively transport calcium ions into the SR, a specialized intracellular calcium store in muscle cells.
* **Mitochondrial calcium uniporter:** This transporter allows calcium ions to enter mitochondria, where they can be used to regulate mitochondrial function.
**Regulation:**
* **Calcium-binding proteins:** These proteins, such as calmodulin and troponin C, bind calcium ions and undergo conformational changes that activate downstream signaling pathways.
* **Calcium-sensitive enzymes:** These enzymes, such as protein kinases and phosphatases, are activated by changes in calcium concentration and regulate various cellular processes.
* **Calcium signaling pathways:** These intricate networks of proteins and enzymes allow cells to translate changes in calcium concentration into specific cellular responses.
In summary, the regulation of cytosolic calcium ion concentration involves a delicate balance between influx, efflux, and sequestration mechanisms, all of which are tightly controlled by a complex network of signaling pathways. This precise control ensures that calcium ions can act as a versatile second messenger, mediating a wide range of cellular processes essential for normal cell function and survival.'
