WormMine: ExpressionPattern Expr2629

• Pattern: Examination of the zag-1::ZAG-1-GFP(zdIs39) strain revealed relatively faint GFP expression in neuronal nuclei from mid to late embryogenesis and during the L1 stage. Widespread expression was seen in head and tail regions containing differentiating neurons beginning around the comma stage that diminished as embryogenesis continued. Expression remained in a few neurons at hatching and was typically nonexistent by midlarval stages. Transient expression was also detected in the postembryonic Pn.a neuroblasts and their descendants during the L1. Thus, zag-1 is expressed transiently in most or all neurons during embryogenesis and in the Pn.a-derived ventral cord neurons during the L1.
