Neuronal death or dismemberment mediated by Sox14

The pruning of unneeded axons and dendrites is crucial for circuitry maturation, but poorly understood on the molecular level. During Drosophila metamorphosis, the transcription factor Sox14 acts as a context-dependent mediator of death, axonal or dendritic pruning. Its transcriptional target Mical acts specifically in dendrite pruning.
