Transcriptional regulator which promotes dendrite growth by suppressing, either directly or indirectly, the expression of the microtubule-severing protein spas (PubMed:21368042). Determines multipolar neuron morphology in postmitotic neurons by positively regulating the expression of genes involved in nuclear positioning including several dynein genes and the nuclear migration protein nudC (PubMed:26490864). Highly enriched in the peripheral nervous system but is absent from the central nervous system (PubMed:21368042). Expressed in neurons with more than one dendrite including da neurons, bd neurons and the dmd1 neuron but undetectable in neurons with single dendrites such as external sensory organ neurons and chodonotal neurons (PubMed:26490864). Severely reduced growth of microtubule-based dendritic branches and elevated levels of microtubule-severing protein spas (PubMed:21368042). Gradual conversion of multipolar neurons into the bipolar or unipolar morphology (PubMed:26490864). Belongs to the krueppel C2H2-type zinc-finger protein family.
