An under-studied microtubule-associated protein is found to regulate axon growth and branching by modulating microtubule-based organelle transport through its dual interactions with microtubules and the conventional kinesin motor.
Disrupting synapse formation between the retina and the brain in zebrafish larvae-by eliminating the molecular motor Kif5A-triggers a compensatory increase in the branching of retinal axons aimed at restoring synapse number.
Epidermal cells in vertebrates and invertebrates ensheath portions of somatosensory neurons via a conserved morphogenetic mechanism, and this ensheathment regulates morphogenesis and function of Drosophila nociceptive neurons.
Analysis of embryonic mouse diaphragm reveals muscle and nerve left–right asymmetries set by a Nodal-dependent genetic cascade, which imprints different molecular signatures to left and right motoneurons that shape their innervation pattern.
A continuously expressed LIM HD factor, Lmx1b, acts at successive stages to orchestrate the progressive morphological maturation of a long-range profusely arborized neuromodulatory axonal projection pathway.
