Our latest review is out. We take a deep dive into the human mutations in microtubule motors that drive devastating neurodevelopmental and neurodegenerative diseases. Taking in motor protein biophysics, animal models of disease as well as patient phenotypes. onlinelibrary.wiley.com/doi/full/10....
Graphical abstract summarising the impact of defective microtubule motors on axonal transport. Kinesins (green) and dyneins (magenta) maintain balance along the length of the axon. When disease causing mutations cause either hyper or hypo activity, the loss of balance results in axon dieback.
