Kinesin proteins use a unique 'head-over-head' mechanism to propel themselves forward, allowing them to transport vital cargo through the cell. Researchers have discovered that this process is controlled by the breakdown of ATP and involves a rocking motion that allows kinesin to complete long-distance walks in a few seconds.
The discovery reveals how the kinesin motor generates motion along microtubule tracks, with a key role played by the neck linker. This understanding could lead to medical therapies targeting kinesin activity in cancer and neurodegenerative diseases.
Researchers have figured out how kinesin motors separate chromosomes, distribute embryonic material, and transport precious cargo in organisms. The discovery reveals a crucial leapfrog motion that allows the motors to move along microtubules, generating force to haul objects up to a thousand times their own size.
