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.
