FLP-ON::TIR1 system for AID-tagged protein degradation in neurons. High levels of TIR1(F79G) expression in neurons by rgef-1p::FLP with co-expression of membrane markers. bmdSi362 contains the ubiquitous rpl-28 promoter driving expression of FRT3-LCK::mNG-STOP::FRT3::TIR1(F79G)::2A::PH::2xmKate2 construct dependent upon tissue-specific FLPase.

JEL1197 C. elegans wrdSi3 II; dpy-27(xoe41[dpy-27::AID::myc]) III; him-8(me4) IV. Show Description
wrdSi3 [sun-1p::TIR1::F2A::mTagBFP2::AID*::NLS::tbb-2 3'UTR] (II:0.77). Endogenous dpy-27 locus tagged with AID element and myc to create a conditional allele using the auxin-inducible degron (AID). In absence of auxin, ~40% of worms are male due to him-8(me4) mutation. In the presence of auxin, ~100% of worms are male (hermaphrodite-lethal due to degradation of AID-tagged DPY-27).

JTL611 C. elegans hsf-1(ljt3[hsf-1::degron::gfp]) I; ieSi57 II; unc-119(ed3) III. Show Description
ieSi57 [eft-3p::TIR1::mRuby::unc-54 3'UTR + Cbr-unc-119(+)] II. Endogenous hsf-1 tagged with the auxin-inducible-degron and GFP allows depletion of endogenous HSF-1 in the somatic tissues upon auxin treatment. Animals treated with 1mM of auxin when eggs are laid will arrest in L1 or L2 stage. Reference: Edwards SL, et al. Cell Rep. 2021 Aug 31;36(9):109623. PMID2021 Aug 31;36(9):109623. PMID: 34469721
KG5148 C. elegans unc-104(ce833[5xMyc::AID::unc-104+sup-1(e995)]) II. Show Description
The Auxin Inducible Degron (AID) flanked by a 5X Myc/spacer tag on left and a single spacer on the right is fused to the N-terminus of the unc-104 gene. Allows conditional degradation of UNC-104 protein when combined with tissue specific expression of TIR1 in the presence of 1 mM Auxin in plate media. Note: KG5148 does not express TIR1. On standard plates: wild type growth, appearance, and locomotion rate. For animals expressing a TIR1 transgene in the nervous system: Animals that hatch and develop on 1 mM Auxin plates generally remain tightly coiled near the location of hatching and exhibit slow growth (up to 7 days to reach adulthood, with 98% reaching adulthood by 7 days). Adults placed on Auxin abruptly lose about 75% of their locomotion function between 6 and 12 hours after plating. The remaining locomotion function is lost gradually between 12 and 52 hours.
