Patronin governs minus-end-out orientation of dendritic microtubules to promote dendrite pruning in Drosophila.

abstract：:Dyneins are motor proteins responsible for transport in the cytoplasm and the beating of axonemes in cilia and flagella. They bind and release microtubules via a compact microtubule-binding domain (MTBD) at the end of a coiled-coil stalk. We address how cytoplasmic and axonemal dynein MTBDs bind microtubules at near a...
