The complete upstream conserved region of nerfin-1 is fused upstream of sequence encoding the DsRed(T4) fluorescent protein tagged with a nuclear localization signal (Tag:NLS(tra)).
DiscRFPnerfin-1.1 is expressed neuroblasts, ganglion mother cells and neurons of the embryonic/larval CNS as well as in neurons of the embryonic/larval PNS and eye disc.
