Transcript of Motor Proteins

Motor proteins enable movement in cells and tissues. Motor proteins utilize the energy of ATP, hydrolysis to move cargoes such as chromosomes and vesicles along the cytoskeleton's microtubule networks. They play a major role in almost all aspects of intracellular transport.
Motor Proteins

Motor proteins are located in the cytoskeleton in the cytoplasm.
Where are they?
Viruses interact with the cytoskeleton and motor proteins in different stages during their replication cycle. Without motor proteins viruses can not properly implant and spread within the cell.
Microfilaments are long thin fibers that provide mechanical strength to the cell. Also links trans membrane cytoplasmic proteins.
Intermediate filaments- they are cytoplasmic fibers averaging 10 nm in diameter. They are each constructed of one or more proteins. Examples are keratins, nuclear lamins, and neurofilaments.
Microtubules-Straight hollow cylinders averaging 25nm in diameter built of tubulin and tubulin dimers they are the most associated with motion.
Cell structure
Motor proteins interact with collagens, keratins, elastin, and actin.
Other proteins/structures it interacts with.
When motor proteins are damaged or missing there would be a lack of movement.
Effect on cell/virus without motor proteins
Myosin- Myosin motors act upon actin filaments to generate cell surface contractions and other morphological changes, as well as vesicle motility, cytoplasmic streaming and muscle cell contraction.
Dynein- Dynein microtubule based motor superfamilies move vesicles and organelles within cells
Other examples of interactions
