Transport in a Molecular Motor System
Intracellular transport in eukarya is attributed to motor proteins that transduce chemical energy into directed mechanical energy. This suggests that, in nonequilibrium systems, fluctuations may be oriented or organized to do work. Here we seek to understand how this is manifested by quantitative mathematical portrayals of these systems. 1991 Mathematics Subject Classification. 34D23,35K50,92C3...
متن کاملReviewThe Molecular Motor Toolbox for Intracellular Transport
transport involves molecular motor proteins that carry cargo directionally along a cytoskeletal track (myosins along actin and kinesins and dyneins along microtu-the origins of the molecular motors and the intracellular transport strategies employed by various organisms. While prokaryotes contain cytoskeletal filaments, the Eukaryotic cells create internal order by using protein motors to trans...
متن کاملThe Molecular Motor Toolbox for Intracellular Transport
Eukaryotic cells create internal order by using protein motors to transport molecules and organelles along cytoskeletal tracks. Recent genomic and functional studies suggest that five cargo-carrying motors emerged in primitive eukaryotes and have been widely used throughout evolution. The complexity of these "Toolbox" motors expanded in higher eukaryotes through gene duplication, alternative sp...
متن کاملTransport of molecular motor dimers in burnt-bridge models
The dynamics of molecular motor dimers, consisting of rigidly bound particles that move along two parallel lattices and interact with underlying molecular tracks, is investigated theoretically by analyzing discretestate stochastic continuous-time burnt-bridge models. In these models the motion of molecular motors is viewed as a random walk along the lattices with periodically distributed weak l...
