In the cytoplasm, actin monomers polymerize into actin filaments (AFs), which constitute the core elements of the actin cytoskeleton, providing mechanical support to the cytoplasm and serving as tracks for myosin-dependent intracellular transport [ 22, 23].
Much evidence indicates that cytoskeletal filaments on the cytoplasmic face of the membrane exert spatio-temporal control on growth and shape of the sacculus by serving as tracks for the murein (holo) enzymes.
He worked for the United States Information Agency and set up a training program and served as track coach for athletes in the new African nations.
Microtubules often serve as tracks for the transport of membrane vesicles in the cell, carried by the motor proteins kinesin and dynein.
Their original wood-spoke wheels replaced with heavy flanged-steel railcar wheels, the Fords served as track-inspection cars and even railyard switcher engines.
Mr. Snowden, who is a board member of a nonprofit group called the Freedom of the Press Foundation, said he was concerned that cellphones and smartphones serve as tracking devices that automatically create electronic dossiers that give third parties, including governments, detailed information on location.
In S. cerevisiae, formins assemble actin cables, which serve as tracks for myosin-dependent intracellular transport.
Actin cables serve as tracks for myosin V delivery of growth vesicles to cell poles [2 4].
Actin also functions in intracellular transport, with the prevailing view that filamentous actin (F-actin) cables serve as tracks for motor-driven transport of cargo [1, 6].
Microtubules have been regarded as critical structures for stable neuronal morphology because they serve as tracks for long-distance transport, provide dynamic and mechanical functions, and control local signaling events.
