What happened
Scientists identify kinesin-2 motor assemblies that selectively transport proteins to specific regions within neurons Sadie Harley scientific editor Robert Egan associate editor Intracellular transport is a vital process that allows cells to move proteins and…
Why it matters
This process is especially important in neurons, which have highly polarized structures with long extensions such as axons and dendrites.
Common ground
For neurons to function properly, proteins must be transported accurately to specific regions, such as the axon initial segment (AIS), a specialized site for initiating electrical signals.
