NPR-17 was previously reported to be expressed in a subset of head and tail neurons, including the AUAs and PVPs (Harris et al., 2010). Additional analysis has also identified npr-17::gfp expression in the ASIs.
UNC-43 expression was notably enriched in the TIR-1-containing puncta in the AWC axon. UNC-43 has previously been shown to be enriched in post-synaptic domains (Rongo and Kaplan 1999). These results suggest that UNC-43 resides at post-synaptic regions of AWC.
