N16 is the key domain in the N terminus of WldS that is essential for WldS-like axon protection. WldS, Nmnat1, ΔN16-WldS, and N16-Nmnat1 were expressed in ORNs using OR22a-Gal4, axons were severed, and the number of remaining intact GFP+ severed axons were scored at the time points indicated. n ≥ 10 for all genotypes; **, P < 0.01. Error bars represent SEM.
