Probable transcription factor, involved in determining neuroblast cell fate, morphogenesis and aspects of terminal differentiation in both left/right symmetric and asymmetric neuronal lineages. Expressed in both symmetric and asymmetric neuronal lineages (PubMed:21698137). In the posterior embryo, expressed in PVQ/HSN/PHB neuroblasts and their descendants (PubMed:14627726, PubMed:21698137). Expressed in the sensory ASE neuron lineage (PubMed:21698137). RNAi-mediated knockdown disrupts differentiation of ASE L/R sensory neurons.
