kasEx80 [oig-1p::tagRFP::unc-54 3'UTR + pha-1(+)]. Maintain at 25C to maintain array. RFP driven by minimal oig-1 promoter for expression in VD-type GABAergic motor neurons. This construct uses the minimal length of promoter containing overlapping LIN-39 and UNC-30 ChIp-seq peaks (deletion of the single LIN-39 binding site within it compromised GABAergic motor neuron expression). Whereas other available oig-1 constructs are expressed ectopically in cholinergic motor neurons in unc-3 mutants, expression of this construct remains exclusively in GABAergic motor neurons.

kasEx147 [oig-1p(1.6kb)::GFP::unc-54 3'UTR + myo-2p::GFP]. Pick worms with GFP+ pharynx to maintain array. Unc. 1.6kb cis-regulatory region (-2.6-1.0kb) upstream of oig-1 was fused to GFP with the unc-54 3'UTR. oig-1 uses mulitple cis-regulatory regions to achieve different expression patterns in motor neurons; this construct drives expression specifically in cholinergic motor neurons. Construct was injected into N2 worms. Reference: Feng W, et al. Elife. 2020 Jan 3;9. pii: e50065. doi: 10.7554/eLife.50065.

kasEx149 [oig-1p(2.6kb_del)::GFP::unc-54 3'UTR + myo-2p::GFP]. Pick worms with GFP+ pharynx to maintain array. Unc. 2.6kb cis-regulatory region with 200bp deletion removing predicted LIN-39 binding site upstream of oig-1 was fused to GFP. Expression of oig-1::GFP in GABAergic motor neurons is been abolished; expression was observed specifically in cholinergic motor neurons of the ventral nerve cord. Reference: Feng W, et al. Elife. 2020 Jan 3;9. pii: e50065. doi: 10.7554/eLife.50065.

kasEx151 [oig-1p(2.6kb_del)::GFP::unc-54 3'UTR + myo-2p::GFP]. Pick worms with GFP+ pharynx to maintain array.

Expression of oig-1::GFP in GABAergic motor neurons is retained, but eliminates ectopic expression in cholinergic motor neurons of the ventral nerve cord. Reference: Feng W, et al.
