Dynein transports … NettetWhat is the role of motor proteins during mitosis? Mitosis requires the trafficking of proteins along microtubules to produce two daughter cells with the same number of chromosomes as the parent cell. Motor proteins therefore have important roles in protein transport along the microtubules of the mitotic spindle during mitosis.

Spindle Fibers Definition and Function - ThoughtCo

Motor proteins are the driving force behind most active transport of proteins and vesicles in the cytoplasm. Kinesins and cytoplasmic dyneins play essential roles in intracellular transport such as axonal transport and in the formation of the spindle apparatus and the separation of the chromosomes during mitosis and meiosis. Axonemal dynein, found in cilia and flagella, is crucial to cell motility, for exampl… Nettet14. apr. 2024 · Abstract.
