bmdSi282 [^loxN^rgef-1p::mKate2-STOP-STOP-VHH4GFP::DAMc1]. Wild-type growth and movement. NanoDam toolkit will allows identification of direct genomic targets of TFs as well as chromatin modifiers. In this system, Dam methylase is fused with a binding reagent, an anti-GFP nanobody (vhhGFP4). Thus, genome-wide profiling can be achieved by combining cell type-specific Dam::vhhGFP4 fusion constructs with GFP knock-in alleles.

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. High levels of TIR1(F79G) can be expressed in specific tissue or cell types via FLPase activity, allowing spatiotemporally-targeted degradation of AID-tagged proteins. Reference: Xiao Y, et al.

This strain forms 20% dauers at 15C. At 25C there occurs about 25% embryonic arrest and about 75% L1 arrest. The e979 mutation results in an amino acid substitution, C146Y, in the ligand-binding domain of the DAF-2 receptor. [CGC received new stock of DR1942 September 2002. Previous stock was probably m41 and not e979.] [June 2004: Patrice Albert has confirmed the mutation in this stock: Repeat of sequencing for CGC collection strain DR1942 [daf-2(e979)] is complete. The strain does carry a C146Y mutation (coding strand TGC to TAC) [Mutation position is at 143, not 146, based on the amino acid sequence shown in Wormbase for daf-2. It's the C in partial sequence EKRCGPI of Exon 5.].]
