Microtubules and microtubule-associated proteins
Current Opinion in Cell Biology, 1995Microtubule research is becoming increasingly diverse, reflecting the many isoforms and modifications of tubulin and the many proteins with which microtubules interact. Recent advances are particularly visible in four areas: microtubule motor proteins (their structures, stepping modes, and forces); microtubule nucleation (the roles of centrosomes and ...

Microtubule-Associated Proteins and the Flexibility of Microtubules
Biochemistry, 1995Experiments were conducted to learn whether the binding of microtubule-associated proteins (MAPs) to microtubules alters the flexibility of the microtubules. Flexibility was measured in vitro by two established techniques. The first employed measurement of the bending of the microtubule in a flow of buffer; the second involved repeated measurement of ...

Microtubules, microtubule-interfering agents and apoptosis
Apoptosis, 2003Microtubules are dynamic polymers that play crucial roles in a large number of cellular functions. Their pivotal role in mitosis makes them a target for the development of anticancer drugs. Microtubule-damaging agents suppress microtubule dynamics, leading to disruption of the mitotic spindle in dividing cells, cell cycle arrest at M phase, and late ...

Microtubules and spermatogenesis
Seminars in Cell & Developmental Biology, 2014Microtubules are dynamic polymers of tubulin subunits that underpin many essential cellular processes, such as cell division and migration. Spermatogenesis is the process by which spermatogenic stem cells undergo mitotic and meiotic division and differentiation to produce streamlined spermatozoa capable of motility and fertilization.

Microtubule nucleation is the process in which several tubulin molecules interact to form a microtubule seed. Microtubule nucleation occurs spontaneously in purified tubulin solutions, and molecular intermediates between tubulin dimers and microtubules have been identified.

Microtubules are rigid cytoskeletal filaments, and their mechanics affect cell morphology and cellular processes. For instance, microtubules for the support structures for extended morphologies, such as axons and cilia. Further, microtubules act as tension rods to pull apart chromosomes during cellular division. Unlike other cytoskeletal filaments (e.g.

Isolation of Microtubules and Microtubule-Associated Proteins
2016Microtubules are essential cellular structures in plant cells. They are polymerized from tubulin dimers and are regulated by microtubule-associated proteins (MAPs). Here, we describe a protocol for purifying tubulin dimers and MAPs from plant cells.

Microtubules and Microtubule Motors: Mechanisms of Regulation
1996Microtubule-based motility is precisely regulated, and the targets of regulation may be the motor proteins, the microtubules, or both components of this intricately controlled system. Regulation of microtubule behavior can be mediated by cell cycle-dependent changes in centrosomal microtubule nucleating ability and by cell-specific, microtubule ...

Microtubules are fibrous elements in the cytoplasm of eukaryotic cells, where they perform a wide variety of functions. Microtubules are major organizers of the cell interior and are vitally involved in motility events such as chromosome migration during cell division. To fulfill their physiological function, microtubule arrays have to undergo dramatic

Microtubules were regularly demonstrated in lens cells. They were especially abundant in the cortex at the equator where the movement of lens cells is most active. The microtubules may serve to maintain the shape and rigidity of the lens cell at the portion of constant movement.
