- n. Any of the proteinaceous cylindrical hollow structures that are distributed throughout the cytoplasm of eukaryotic cells, providing structural support and assisting in cellular locomotion and transport.
- n. small tubes made of protein and found in cells; part of the cytoskeleton.
- n. a microscopically small tubule
“The common view was that microtubules all began at the cell body; the graph should have simply shown a decrease in microtubule number as one looked further from the cell body.”
“John Sulston had already found that these cells had unique bundles of very prominent microtubules (the cells were originally called the microtubule cells), so they were very easy to see in the micrographs.”
“Marching along a microtubule is the kinesin motor, the hero of our story, carrying a huge sack of proteins to be delivered to a pre-determined place in the cell.”
“Marching along a microtubule is the kinesin motor, the hero of our story, carrying”
“Both mitotic and meiotic spindle microtubules are stabilized and organized into a bipolar shape by a number of accessory proteins, called microtubule motors and MAPs (for "Microtubule-Associated Proteins")”
“Since CLIPR-59, CLIP-170-related protein, has recently been identified as a microtubule binding protein associated with lipid rafts, we analyzed the role of GD3-CLIPR-59 association in lymphoblastoid T cell apoptosis triggered by CD95/Fas.”
“Other activities of specialized kinesin-like proteins, such as microtubule depolymerization by proteins of the kinesin 13 family, also require ATP hydrolysis”
“I isolated touch mutants, worked on microtubule structure, studied lineage mutants, investigated neural circuitry, and even did some work on neurotransmitters.”
“When I was a graduate student Bob Perlman had ordered at least one hundred reprints of every paper, so when my microtubule paper was accepted, I asked Jonathan how many reprints I should order.”
“A meiotic microtubule doesn't grab a chromosome at random?”
Looking for tweets for microtubule.
