title: Tubulin delivery: polymerization chaperones for microtubule assembly?
abstract: A new paper by Slep and Vale in a recent issue of Molecular Cell provides structural clues as to how three different +TIP proteins interact with tubulin and suggests that +TIPs deliver oligomers of tubulin dimers to growing microtubule ends.
