How neurons get their branching shapes

For more than a hundred years, people have known that dendritic arbors—the projections that neurons use to receive information from other neurons—differ in size and shape depending on neuron type. Now, researchers at ...

Giant proteins determine properties of neurons

Giant membrane-associated proteins called ankyrins extend into the cytoplasm to arrange and stabilize microtubules in axons and synapses. This determines not only the diameter and hence the functional properties of axons, ...

Microtubules are a component of the cytoskeleton. These rope-like polymers of tubulin can grow as long as 25 micrometers and are highly dynamic. The outer diameter of microtubule is about 25 nm. Microtubules are important for maintaining cell structure, providing platforms for intracellular transport, forming the spindle during mitosis, as well as other cellular processes. There are many proteins that bind to the microtubule, including motor proteins such as kinesin and dynein, severing proteins like katanin, and other proteins important for regulating microtubule dynamics.
