The 3'UTR and 3' conserved sequence cluster of nerfin-1 is fused upstream of sequence encoding the DsRed(T4) fluorescent protein tagged with a nuclear localization signal (Tag:NLS(tra)).
DiscRFPnerfin-1.13 is expressed in a subset of neuroblasts and their ganglion mother cells at embryonic stage 11 as well as in a subset of neurons in the larval brain, in particular in the larval optic anlage.
