cytoplasmic microtubule

Definition

Target type: cellularcomponent

Any microtubule in the cytoplasm of a cell. [GOC:mah]

Cytoplasmic microtubules are dynamic, filamentous structures that form part of the cytoskeleton in eukaryotic cells. They are composed of α- and β-tubulin dimers that assemble into protofilaments, which in turn associate laterally to form hollow tubes.

Microtubules are highly dynamic structures, constantly undergoing assembly and disassembly. This dynamic instability allows them to rapidly reorganize and adapt to changes in cellular needs.

Key functions of cytoplasmic microtubules include:

- **Cellular shape and organization:** Microtubules provide structural support and help maintain the shape of the cell.
- **Cell division:** During mitosis and meiosis, microtubules form the spindle fibers that attach to chromosomes and pull them apart.
- **Intracellular transport:** Microtubules serve as tracks for motor proteins like kinesin and dynein, which transport vesicles, organelles, and other cellular components throughout the cytoplasm.
- **Organelle positioning:** Microtubules play a role in the positioning of organelles, such as the Golgi apparatus and the endoplasmic reticulum, within the cell.
- **Cell motility:** In some cells, microtubules contribute to cell motility, such as the movement of cilia and flagella.

Cytoplasmic microtubules are organized by microtubule-organizing centers (MTOCs), such as the centrosome in animal cells. The centrosome contains a pair of centrioles and pericentriolar material, which nucleates microtubule assembly. Microtubules grow out from the centrosome towards the cell periphery, creating a dynamic network of filaments throughout the cytoplasm.

The dynamic instability of microtubules is regulated by a variety of factors, including:

- **Microtubule-associated proteins (MAPs):** These proteins can bind to microtubules and influence their stability, assembly, and disassembly.
- **GTP hydrolysis:** Tubulin dimers bind to GTP, and the hydrolysis of GTP to GDP promotes microtubule disassembly.
- **Cellular signaling pathways:** Various signaling pathways can regulate microtubule dynamics in response to environmental cues or cellular needs.'

acetazolamideAcetazolamide: One of the CARBONIC ANHYDRASE INHIBITORS that is sometimes effective against absence seizures. It is sometimes useful also as an adjunct in the treatment of tonic-clonic, myoclonic, and atonic seizures, particularly in women whose seizures occur or are exacerbated at specific times in the menstrual cycle. However, its usefulness is transient often because of rapid development of tolerance. Its antiepileptic effect may be due to its inhibitory effect on brain carbonic anhydrase, which leads to an increased transneuronal chloride gradient, increased chloride current, and increased inhibition.
