Structure, dynamics, and mutation of a gamete fusion protein and comparisons to viral homologues suggest that after trimerization the domain bearing the membrane-inserting fusion loops can pivot with respect to the trimer 3-fold axis.
Genetic analyses combining photoconvertible cell signalling reporters with gain- and loss-of function manipulations reveal a novel role for Notch signalling in controlling Hedgehog response in neural progenitor cells.
A genetic screen and live cell imaging show that a newly identified coiled-coil protein called SAS-7 is the earliest acting factor in centriole assembly yet identified in the roundworm Caenorhabditis elegans.
Large-scale in vivo imaging of the zebrafish left-right organizer (Kupffer's vesicle) combined with fluid dynamics calculations allows to quantitatively test the possible flow detection mechanisms and supports the flow transport of chemical signals as the mechanism of side determination.
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.
