Cyclin-dependentkinase 2 (Cdk2), the master regulator of S phase events during the cell cycle, controls the earliest step in the motile ciliogenesis pathway in quiescent multiciliatedairway epithelial cells.
CRISPR/Cas knockout of intraflagellar transport protein 80 shows that this subunit is absolutely required for ciliogenesis, and biophysical studies reveal that this protein may dimerize the intraflagellar transport complex.
At optimal concentrations, the ciliary inhibitor Cp110 promotes ciliogenesis by localization to previously uncharacterized sites at the basal body, where it recruits ciliary adhesion complexes that mediate basal body interaction with F-actin networks.
Building on previous work (Doroquez et al., 2014), it is shown that the centriole core of the basal body degenerates, but the outer wall remodels to template the ciliary axoneme in a subset of C. elegans ciliated sensory neurons.
Systems-level analysis in vertebrate ciliated epithelial cells shows that the network of genes activated by the transcription factor Rfx2 controls the development, migration, insertion and function of these cells.
Genetic knock-outs of the dynein-2 intermediate chains reveals that both are essential for correct cilia function and transition zone organization, but play different functions in the assembly of dynein-2 motor and in primary cilia formation.
