CELE_C34E10.7, hlh-5, C34E10.7

cnd-1 encodes a basic helix-loop-helix protein that is most closely related to the vertebrate NeuroD transcription factors; during development, CND-1 is predicted to function 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; CND-1::GFP expression begins in early embryogenesis (<20 cells) in four AB descendants and then continues in mitotically active AB-derived neuronal precursors, unidentified nuclei during gastrulation and enclosure, and postmitotic neurons in the head and ventral cord; at hatching CND-1::GFP expression is visible in ventral cord neurons, but this expression disappears completely by the end of the first larval stage; CND-1::GFP does not appear to be expressed in any non-neuronal ectodermal cells, as its expression does not overlap with that of LIN-26.
