A detailed description of the structure of procentriole MT triplet by cryoET, along with its associated non-tubulin proteins and its assembly intermediates, reveals possible molecular mechanism for the procentriole assembly.
Multimegadalton intraflagellar transport (IFT) trains assemble by sequential recruitment of IFT subcomplexes from the cell body to the ciliary basal bodies and tubulin, the main IFT cargo, is loaded briefly before trains depart.
Bardet–Biedl syndrome 3 (BBS3) protein promotes phospholipase D to load onto the BBSome at the ciliary tip for moving out of the cilium via intraflagellar transport.
The symbiotic relationship between Hydra and Chlorella is driven by metabolic co-dependence and characterized by changes in the photobiont genome in terms of lack of genes essential in free-living algae.
