Acts as a transcriptional regulator whose activity is required for several aspects of motor neuron fate specification, including cell division patterns, proper spatiotemporal expression of fate-specific markers, and normal axonal morphology and pathfinding (PubMed:10976055). Involved in regulating glial specification (PubMed:32665354). Expressed in neuroblasts of the AB lineage. More specifically in precursors of the embryonic ventral cord motor neurons. Expressed to a lesser degree in the EMS lineage which generates mostly endoderm and mesoderm tissues. Expressed at the 14 cell embryo stage. Defects in axonal morphology and synaptic connectivity of the ventral cord motor neurons.
