Grows well as a homozgyote. 0.3% sterile at 20C (0.2% have masculinized germ lines). Do not distribute this strain; other labs should request it directly from the CGC. This strain cannot be distributed to commercial organizations. This strain cannot be used for any commercial purpose or for work on human subjects.

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.
