Sentences with phrase «dynein motors»

At Berkeley, Yildiz expanded his studies on the movement of dynein motors and also branched out in a new direction.

Self - organization of dynein motors generates meiotic nuclear oscillations.

The team at Leeds, working within the world - leading Astbury Centre for Structural Molecular Biology, combined purified microtubules with purified dynein motors and added the chemical fuel ATP (adenosine triphosphate) to power the motor.

«Each of the two arms of a dynein motor protein is about 25 nanometres (0.000025 millimetre) long, while the binding sites it attaches to are only 8 nanometres apart.

Not exact matches

To model this molecular motor, the scientists created a molecular dynamics simulation of a dynein protein and applied energy at the ATP binding site to approximate the transfer of energy from ATP.

The axoneme's movement is accomplished via rows of motor proteins called dyneins that are attached along the microtubules and exert force on them so the microtubules «slide» past each other, which then causes the entire axoneme and sperm tail to bend and move.

They are made up of microtubules and many other proteins, including the motor protein dynein.

Researchers at the University of Leeds and in Japan used electron microscopes to capture images of the largest type of motor protein, called dynein, during the act of stepping along its molecular track.

For instance, in the motor neuron connecting the central nervous system to the big toe — which is a single cell a metre long — dynein provides the transport from the toe back to the nucleus.

Earlier this year, Kiyomitsu, working in Cheeseman's lab, saw that during the metaphase cell cycle step a dividing cell uses the motor protein dynein and two signals to perfectly align the cell's mitotic spindle structure in the middle of the cell.

By combining many images of individual motors, we were able to sharpen up our picture of the dynein and build up a dynamic idea of how it moved.

Other motor proteins, called kinesins and myosins, are much smaller and have specific functions, but dynein can turn its hand to a lot of different of functions,» Professor Knight said.

Dr Stan Burgess, at the University of Leeds» School of Molecular and Cellular Biology, who led the research team, said: «Dynein has two identical motors tied together and it moves along a molecular track called a microtubule.

Functional analysis of human microtubule - based motor proteins, the kinesins and dyneins, in mitosis / cytokinesis using RNA interference.

Williams focused on dynein light chains, which were thought to bridge Fyn kinase and other cargo to the molecular motor dynein.

During G1 phase, basal migration of the nucleus requires the plus - end - directed microtubule motor Kif1A, while during G2 phase, apical migration requires the minus - end - directed motor dynein.

Delanoue R., Herpers, B., Davis, I. and Rabouille, C. Drosophila Squid - hnRNP helps dynein switch from a gurken mRNA transport motor to an ultrastructural static anchor in sponge bodies Developmental Cell 13:523 (2007)

The investigators showed that kinesin movement corresponds to traffic from the center of a nerve cell to its axonal tips — and a different motor in the squid's cytoplasm, which was subsequently identified as dynein, travels in the opposite direction.
