The human NimA-related kinases (Neks) recognize divergent substrate motifs, and include Nek10 as a dual-specificity serine/tyrosine kinase, and Nek6, Nek7 and Nek9 as amplifiers of the Plk1 phospho-motif.
Reconstitution of the endosomal Rab cascade reveals that Rab5 binds and activates the Mon1-Ccz1 guanine nucleotide exchange factor, which in turn recruits Rab7 to membranes to drive fusion.
Zebrafish mutants and human endothelial cell experiments reveal that GIPC family endocytic adaptors bind to the Semaphorin receptor PLEXIND1, a critical regulator of vascular development, to negatively modulate its signaling.
The first born excitatory cerebellar nuclei neurons influence the survival of their Purkinje cell partners which stimulate the expansion of granule cells and interneurons to produce functional local circuits.
