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.
Notch ligands from the Delta and Jagged families have distinct roles in epithelial progenitor cell fate of extrapulmonary and intrapulmonary airways and differentially restrict expansion of the neuroendocrine microenvironment.
In mouse brain slices, native delta glutamate receptors carry ionic current and underlie the α1-adrenergic receptor-mediated depolarization of dorsal raphe neurons that drives action potential firing in vivo.
Cytonemes mediate, and are essential for, Wingless signaling from the Drosophila wing disc to disc-associated myoblasts and for Delta-Notch signaling from these myoblasts to the dorsal air sac primordium.
Cells of the xanthophore lineage form projections that allow them to communicate with other pigment cells during adult pigment pattern formation in zebrafish, but not in the closely-related pearl danio.
