WebPerhaps the most fascinating proteins that associate with the cytoskeleton are the molecular motors called motor proteins. These remarkable … WebThese motor proteins (train engines) and the cytoskeleton create a comprehensive network within the cell for moving vesicles (box cars) from one organelle to another or from one …
Directing Traffic: How Vesicles Transport Cargo - University of Utah
WebThree superfamilies of motor proteins power directed movements on microtubules or actin filaments. Myosin motors move on actin filaments, whereas kinesin and dynein motors … Motor proteins utilizing the cytoskeleton for movement fall into two categories based on their substrate: microfilaments or microtubules. Actin motors such as myosin move along microfilaments through interaction with actin, and microtubule motors such as dynein and kinesin move along microtubules … See more Motor proteins are a class of molecular motors that can move along the cytoplasm of cells. They convert chemical energy into mechanical work by the hydrolysis of ATP. Flagellar rotation, however, is powered by a proton pump See more Motor proteins are the driving force behind most active transport of proteins and vesicles in the cytoplasm. Kinesins and cytoplasmic dyneins play … See more Besides the motor proteins above, there are many more types of proteins capable of generating forces and torque in the cell. Many of these … See more • MBInfo - What are Motor Proteins? • Ron Vale's Seminar: "Molecular Motor Proteins" • Biology of Motor Proteins Institute for Biophysical Chemistry, Göttingen See more The importance of motor proteins in cells becomes evident when they fail to fulfill their function.
