calcium ion transmembrane transport

Definition

Target type: biologicalprocess

A process in which a calcium ion is transported from one side of a membrane to the other by means of some agent such as a transporter or pore. [GOC:mah]

Calcium ion transmembrane transport is a fundamental biological process that plays a crucial role in a wide range of cellular functions. This process involves the movement of calcium ions (Ca2+) across cell membranes, driven by the difference in Ca2+ concentrations between the intracellular and extracellular environments. Calcium ion transmembrane transport is mediated by specialized membrane proteins called calcium channels and pumps, which facilitate the selective and regulated movement of Ca2+ ions.

There are two primary mechanisms of calcium ion transmembrane transport:

1. Passive Diffusion: This mechanism occurs when Ca2+ ions move down their concentration gradient, from an area of high concentration to an area of low concentration. This movement does not require energy expenditure by the cell and is typically facilitated by channels that allow the passage of Ca2+ ions through the membrane.

2. Active Transport: This mechanism involves the movement of Ca2+ ions against their concentration gradient, requiring the expenditure of energy by the cell. This process is driven by calcium pumps, which are transmembrane proteins that actively transport Ca2+ ions out of the cell or into specialized intracellular compartments.

The biological significance of calcium ion transmembrane transport lies in its role in regulating a multitude of cellular processes, including:

* Muscle contraction: Ca2+ influx into muscle cells triggers the release of actin and myosin filaments, leading to muscle contraction.

* Neurotransmitter release: Ca2+ influx into nerve terminals stimulates the fusion of synaptic vesicles with the presynaptic membrane, releasing neurotransmitters into the synaptic cleft.

* Cell signaling: Ca2+ ions act as second messengers in intracellular signaling pathways, mediating diverse cellular responses, such as gene transcription and protein synthesis.

* Cellular growth and differentiation: Ca2+ signaling plays a crucial role in regulating cell proliferation, differentiation, and apoptosis.

Dysregulation of calcium ion transmembrane transport can lead to various pathological conditions, including:

* Cardiac arrhythmias: Abnormal calcium ion movement in heart muscle cells can disrupt the electrical activity of the heart, leading to irregular heart rhythms.

* Muscle disorders: Impaired calcium ion transport can result in muscle weakness, fatigue, and cramps.

* Neurodegenerative diseases: Dysregulation of calcium signaling has been implicated in neurodegenerative disorders such as Alzheimer's disease and Parkinson's disease.

In conclusion, calcium ion transmembrane transport is a complex and highly regulated process that plays an indispensable role in maintaining cellular homeostasis and orchestrating a wide range of physiological functions. Understanding the mechanisms and regulation of calcium ion transport is crucial for comprehending the fundamental biology of cells and for developing therapeutic strategies for addressing diseases associated with calcium signaling dysregulation.'

menthol(-)-menthol : A p-menthan-3-ol which has (1R,2S,5R)-stereochemistry. It is the most common naturally occurring enantiomer.

(+-)-menthol : A racemate comprising equimolar amounts of (+)- and (-)-menthol. Both (+-)- and (-)-menthol are used to relieve symptoms of conditions such as bronchitis and sinusitis. When applied to the skin, menthol dilates the blood vessels, giving a sensation of coldness followed by an analgesic effect that relieves itching. It is therefore used in creams and ointments for the relief of pruritis and urticaria.

clozapineclozapine : A benzodiazepine that is 5H-dibenzo[b,e][1,4]diazepine substituted by a chloro group at position 8 and a 4-methylpiperazin-1-yl group at position 11. It is a second generation antipsychotic used in the treatment of psychiatric disorders like schizophrenia.

Clozapine: A tricylic dibenzodiazepine, classified as an atypical antipsychotic agent. It binds several types of central nervous system receptors, and displays a unique pharmacological profile. Clozapine is a serotonin antagonist, with strong binding to 5-HT 2A/2C receptor subtype. It also displays strong affinity to several dopaminergic receptors, but shows only weak antagonism at the dopamine D2 receptor, a receptor commonly thought to modulate neuroleptic activity. Agranulocytosis is a major adverse effect associated with administration of this agent.
