Cilia Biology: You're It! Tagging Proteins for Ciliary Removal

Recent work has resolved the established links between beta-arrestin 2 and the BBSome in controlling ciliary GPCR localization by showing that beta-arrestin 2 regulates the addition of K63-linked ubiquitin chains to tag proteins for removal from the cilia via the BBSome.
