WebApr 12, 2024 · Research Shows Motor Proteins Responsible for Neuron Movements Pennsylvania State University Neurons, which are responsible for producing the signals that ultimately trigger an action like talking or moving a muscle, are built and maintained by classes of motor proteins that transport molecular cargo along elongated tracks called … WebMotor proteins bind and transport several different cargoes including mitochondria, cytoskeletal polymers, autophagosomes, and synaptic vesicles containing neurotransmitters . Axonal transport can be fast or slow, and anterograde (away from the cell body) or retrograde (conveys materials from axon to cell body). Fast and slow transport [ edit] WebMotor proteins bring about movements of cilia and flagella by gripping cytoskeletal components such as microtubules and moving them past each other. A similar mechanism causes muscle cells to contract. How do vesicles travel along the cytoskeleton?
