  • The midbody is an organelle present at the bridge connecting two cells at the end of cell division. Here, the authors use mass spectrometry to define the midbody interactome and uncover a role for PP1 phosphatases in microtubule dynamics and regulation of cytokinesis.

  • Centrioles and cilia are microtubule-based structures of defined architecture, but what regulates this architecture is not clear. Here the authors discover that centrosomal-P4.1-associated-protein (CPAP) binds the α/β-tubulin dimer and licenses it for tubulin delivery contributing to centriolar/ciliary length and architecture control.

  • Centriole duplication requires the loading of centriolar proteins to the daughter centriole during mitosis. Fu and colleagues analyse by 3D-structural illumination microscopy the sequential recruitment of centriolar proteins Cep135, Cep295 and Cep152.

  • Centrioles are essential for the formation of centrosomes, cilia and flagella. The centriolar protein Polo-like-kinase 4 (Plk4) is a key regulator of centriole biogenesis and for maintaining constant centriole number in cells. These authors show that the centriolar protein Asterless (CEP152 in humans) interacts with Plk4 and Sas-4. They find that Asl functions as a scaffold for Plk4 and Sas-4 that facilitates self-assembly and duplication of the centriole, and organization of pericentriolar material.
