The structure of the Ana2 Central Coiled-Coil Domain provides insight into how centriolar cartwheel components may be recruited and assembled, and indicates that cartwheel assembly involves more than just SAS-6 oligomerisation.
Canonical centriole duplication is much less prone to errors than de novo synthesis of centrioles, but neither depends on self-oligomerization of the centriole protein SAS-6.
Unlike mouse embryos, mouse embryonic stem cells are able to use a SAS-6-independent pathway for imperfect centriole biogenesis that is associated with a rich centrosomal milieu and robust PLK4 activity.

The X-ray structure of the SAS-6 cartwheel hub from Leishmania major demonstrates that SAS-6 can be sufficient to determine centriolar cartwheel symmetry.

The dual functional protein, Gorab, associates with the Golgi as a dimer but as a monomer with the procentriole cartwheel protein, Sas6, to mediate centriole duplication.

SAS-5 forms oligomers, through a trimeric coiled coil and novel dimeric domain, that are necessary for centriolar localisation of SAS-5 and for centriole duplication.
Newly discovered interaction between fission yeast SPB and animal centriole components reveals that pericentrin not only functions as a microtubule-nucleator, but also promotes centriole assembly in animals.
Down-regulation of GAS6 by M1 macrophages resulted in impaired efferocytosis for synovial apoptotic cells, causing synovial hyperplasia and obesity-associated OA development.
Building on previous work (Conduit et al., 2014), and contrary to what was previously thought, it is shown that key centrosomal proteins are not recruited to centrosomes as part of large multi-protein assemblies.

A comparison of different bioimage analysis pipelines reveals how deep learning can be used for automatized and reliable analysis of fluorescent features in biological datasets.
