The Fuzzy logistics of intraflagellar transpor t T he planar cell polarity protein Fuzzy (Fuz) promotes ciliogenesis by delivering intrafl agellar transport (IFT) proteins to the basal bodies of primary cilia, Brooks and Wallingford report. Fuz is required for cilia assembly in frogs and mice, but how it supports ciliogenesis is unknown. The protein has no obvious functional domains, though bio...
متن کاملFormin’ the cytokinetic ring
A ll animal and fungal cells assemble a contractile actomyosin ring to divide themselves in two at the end of mitosis. The rings are constructed from actin fi laments formed de novo at the division site and from fi laments that are assembled elsewhere in the cell and transported to the cleavage zone. Both types of fi lament are generated by actinnucleating formin proteins, but whether one sourc...
