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.
The coding sequences of a very highly conserved family of neurogenic transcription factors from different species have evolved to generate proteins that have different life times causing them to display quantitatively different neural induction potentials.
New experiments and theory reveal how the ability to see image details depends upon photoreceptor function and eye movements, and how fruit flies (Drosophila) see spatial details beyond the optical limit of their compound eyes.
Analyses of a developmentally regulated Drosophila myofiber remodeling program provide insight into induced autophagy required for T-tubule membrane reorganization, and uncover a conserved Rab2 role in autophagosome-lysosome fusion.
A single subpopulation of photoreceptors constitutes a shared node in the neural networks that regulate light-dependent maturation of the circadian clock and light-independent refinement of retinal ganglion cell projections to the brain.
The organization of layered/laminated axon projections in specific regions of the fruitfly central brain is regulated by short-range repulsive guidance and is critical for local inhibitory circuit formation and function.
