|---|---|---|---|
| KRA102 | lin-39(kas1) III; ynIs40 V; unc-3(n3435) X. | C. elegans | ynIs40 [flp-11p::GFP] V. kas1 is a point mutation in the second intron splice acceptor site, disrupting splicing. Worms are vulvaless and have severe locomotion defects. Reference: Feng W, et al. Elife. 2020 Jan 3;9. pii: e50065. doi: 10.7554/eLife.50065. |
| KRA235 | pha-1(e2123) III; kasEx80. | C. elegans | 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. Reference: Feng W, et al. Elife. 2020 Jan 3;9. pii: e50065. doi: 10.7554/eLife.50065. |
| KRA315 | kasIs7. | C. elegans | kasIs7 [snb-1p::C9 ubi + myo-2::GFP]. The transgene drives expression of 75 GGGGCC repeats under the control of snb-1 promoter. The repeats are flanked with human C9orf72 intronic sequences. Reference: https://pubmed.ncbi.nlm.nih.gov/34654821/ |
| KRA317 | kasIs9. | C. elegans | kasIs9 [snb-1p::(delta)C9 ubi + myo-2::GFP]. The transgene has the snb-1 promoter followed by nanoluciferase sequence and unc-54 3'UTR. Reference: https://pubmed.ncbi.nlm.nih.gov/34654821/ |
| KRA334 | kasEx73. | C. elegans | kasEx73 [unc-3p::dsUnc-3(RNAi) + myo-2p::GFP]. Pick GFP+ to maintain array. Array carries a construct with the unc-3 promoter driving transcription of a hairpin targeting unc-3 for RNAi depletion in cholinergic motor neurons. Reference: Feng W, et al. Elife. 2020 Jan 3;9. pii: e50065. doi: 10.7554/eLife.50065. |
| KRA345 | cfi-1(kas16[mNG::AID::cfi-1]) I. | C. elegans | mNeonGreen and AID tags inserted into endogenous cfi-1 locus. Transgene can be degraded in a background expressing TIR1 co-factor supplemented with auxin. Reference: Li Y, et al. Elife. 2020 Oct 1;9:e59464. doi: 10.7554/eLife.59464. PMID: 33001031. |
| KRA437 | unc-3(n3435) X; kasEx147. | C. elegans | 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. |

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. |

Unc. 2.6kb cis-regulatory region with 300bp deletion removing predicted LIN-39 binding site upstream of oig-1 was fused to GFP.
