Sentences with phrase «called 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.

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.

Not exact matches

Using this biologically accurate model of how dynein moves the microtubules within the axoneme, Ingber and Reilly created a short film called «The Beginning,» which draws parallels between sperm swimming toward an egg and spaceships flying toward a planet in space, giving an artistic bent to a scientific topic.

The team found changes in a gene encoding a previously unknown «dynein,» a protein that moves like a railroad locomotive along cytoskeletal fibers called microtubules, hauling other molecules as cargo.

Indeed, the group found that the affected gene, named left - right dynein (lrd), comes on in the «node» — a key source of patterning signals — just before the appearance in the mouse embryo of the first known left - right asymmetries, the left - sided expression of two genes called nodal and lefty.

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.
