The Notch signaling pathway can use its various ligands, receptors, and Fringe proteins to generate diverse intra- and intercellular signaling behaviors.
Analysis of a variant without lysine in the intracellular domain reveals a ubiquitylation-independent signalling activity of the DSL ligand Delta and novel functions of the Neuralized and Mindbomb1 E3-ligases during Notch signalling.
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.
