Latest Microtubule Stories
Researchers at the Carnegie Institution for Science, with colleagues at the Nara Institute of Science and Technology, observed for the first time a fundamental process of cellular organization in living plant cells: the birth of microtubules by studying recruitment and activity of individual protein complexes that create the cellular protein network known as the microtubule cytoskeletonâ€”the scaffolding that provides structure and ultimately form and shape to the cell.
A new University of Georgia study published in the journal Nature has identified a critical enzyme that keeps traffic flowing in the right direction in the nervous system, and the finding could eventually lead to new treatments for conditions such as Alzheimer's and Parkinson's disease.
It's safe to say that cilia, the hairlike appendages jutting out from the smooth surfaces of most mammalian cells, have long been misunderstood â€“ underestimated, even.
Whitehead Institute researchers have determined a key part of how cells regulate the chromosome/microtubule interface, which is central to proper chromosomal distribution during cell division.
A University of Utah researcher helped discover how a "wimpy" protein motor works with two other proteins to gain the strength necessary to move nerve cells and components inside them.
Lifeâ€™s smallest motor, a protein that shuttles cargo within cells and helps cells divide, does so by rocking up and down like a seesaw.
Studies with fruit flies have shown that the specialized nerve cells called neurons can rebuild themselves after injury.
â€œA biologist, a physicist, and a nanotechnologist walk into a ...â€ sounds like the start of a joke. Instead, it was the start of a collaboration that has helped to decipher a critical, but so far largely unstudied, phase of how cells divide.
Friction is the force that resists the relative motion of two bodies in contact. The same is true on the nanoscale: Molecular motors have to fight the friction created between them and their tracks.
Stalled microtubules might be responsible for some cases of the neurological disorder Charcot-Marie-Tooth (CMT) disease, Tanabe and Takei report in the June 15, 2009 issue of the Journal of Cell Biology
Arbacia punctulata is a species of Arbacia genus of purple-spined sea urchins. Its natural habitat is in the Western Atlantic Ocean. It can be found in shallow water from Massachusetts to Cuba and the Yucatan Peninsula, from Texas to Florida in the Gulf of Mexico, the coast from Panama to French Guiana and in the Lesser Antilles, normally on sandy, rocky, or shelly bottoms. It is omnivorous, consuming a wide variety of preys. It’s been shown that it is galactolipids, rather than...
