uIs31 [mec-17p::GFP] III. pg79[TBB-1::TagRFP-T + loxP] is a CRISPR-mediated c-external tag in the endogenous tba-1 locus. Reference: Lockhead D. et al Mol Biol Cell. 2016 Nov 15; 27(23): 3717–3728.

qSi77 [mex-5p::eGFP::3xFLAG::tbb-1 3'utr::gpd-2 SL2 splice site::mCherry::3xMyc::pgl-1 RGG repeat::tbb-1 3'utr and intergenic region + unc-119(+)] inserted into ttTi5605 on LG II. References: Noble DC, et al. Genetics. 2016 Jan;202(1):221-34.

qSi380 [mex-5p::eGFP::3xOLASS::linker::his-58::MODC pest::3xboxb::tbb-2 3'UTR::SL2 trans-splice site::mCherry::3xV5::linker::his-58::MODC pest::mutant 3xboxb::tbb-2 3'utr::tbb-1 intergenic region] IV. Worms are fertile at 20C. Improved tethering assay for use in the C. elegans germline. GFP reporter mRNA is under control of a germline-expressed mex-5 promoter and has three boxB stem-loops in its 3'UTR. The RNA-binding protein (RBP) is tagged with lamda-N. The nascent transcript driven by mex-5 promoter is resolved by trans-splicing into two mRNAs that encode distinct reporters. The GFP reporter RNA has three functional boxB stem-loops in its 3'UTR; the mCherry reporter 3'UTR has three mutated boxB stem-loops that do not bind lamda-N and therefore provides an internal control. Addition of an OLLAS tag to GFP and a V5 tag to mCherry enables sensitive immunostaining and immunoblotting. Reference: Doenier J, et al. RNA. 2021 Jun;(6)643-652. PMID: 33727224.

qSi380 [mex-5p::eGFP::3xOLASS::linker::his-58::MODC pest::3xboxb::tbb-2 3’utr::SL2 trans-splice site::mCherry::3xV5::linker::his-58::MODC pest::mutant 3xboxb::tbb-2 3'utr::tbb-1 intergenic region] IV. Worms are fertile at 20C. Improved tethering assay for use in the C. elegans germline. GFP reporter mRNA is under control of a germline-expressed mex-5 promoter and has three boxB stem–loops in its 3′UTR. The RNA-binding protein (RBP) is tagged with lamda-N. The nascent transcript driven by mex-5 promoter is resolved by trans-splicing into two mRNAs that encode distinct reporters. The gfp reporter RNA has three functional boxB stem–loops in its 3′UTR; the mCherry reporter 3′UTR has three mutated boxB stem–loops that do not bind lamda-N and therefore provides an internal control. Addition of an OLLAS tag to GFP and a V5 tag to mCherry enables sensitive immunostaining and immunoblotting. Reference: Doenier J, et al. RNA. 2021 Jun;(6)643-652. PMID: 33727224.

otEx4548 [tbb-1(fosmid)::SL2::NLS::YFP::H2B + pha-1(+)]. Maintain at 25C to select for array. Ubiquitous nuclear YFP expression. Reference: Stefanakis N., Carrera I., Hobert O. Neuron. 2015 Aug 19;87(4):733-50.

GFP tag inserted into the endogenous tbb-1 locus. GFP signals are detected at the epidermis, germline, intestine, muscle, and neurons. Reference: Honda Y, et al. J. Cell. Sci. 2017 May 1;130(9):1652-1661. PMID: 28302908.

bsIs20 [tbb-1p::mCherry::tbb-2::tbb-2 3′UTR + unc-119(+)]. Maintain at 20C or lower. dyn-1(luv35) is a CRISPR-engineered mutation reproducing the dyn-1(ky51) allele. GFP inserted at the C terminus of endogenous plk-1 locus. At 26C, embryos exhibit elevated centrosomal PLK-1::sfGFP levels, persistence of PLK-1::sfGFP at centrosomes during late mitosis, and mild defects in intercellular bridge (midbody) assembly. Strain expressing mCherry::tubulin and endogenously tagged PLK-1::sfGFP enables live imaging of spindle dynamics and centrosomal PLK-1 localization during mitosis in embryos.
