cpIs89 [wrt-2p::2x mTurquoise2::PH::tbb-2 3'UTR loxN] I. cpIs85 [egl-20p::2x mKate2::PH::3xHA::tbb-2 3'UTR loxN] II. mNeonGreen::3xFlag tag inserted at the C-terminus of the endogenous egl-20 locus. 2x mTurquoise2::PH membrane marker expressed in seam cells, Q neuroblasts, and many hypodermal cells. Expression of 2x mKate2::PH membrane marker driven by egl-20 upstream intergenic sequence. cpIs89 is a single copy transgene inserted at Chr I:2851088 near ttTi4348 using Cas9-triggered homologous recombination. cpIs85 is a single copy transgene inserted at Chr II:8420157-8420243 near ttTi5605 using Cas9-triggered homologous recombination.

cpIs158 [myo-3p::pat-3sp::2x vhhGFP4::CD8 tm::2x mTurquoise2::PH::tbb-2 3'UTR loxN] I. cpIs130 [wrt-2p::2x mKate2::PH::3xHA::let-858 3'UTR::tag-168p::HisCl1::tbb-2 3'UTR loxN] II. YPET::3xFlag tag inserted at the C-terminus of the endogenous egl-20 locus. cpIs158 expresses a membrane-anchored anti-GFP nanobody (Morphotrap) in body wall muscles. This version of Morphotrap consists of extracellular 2x vhhGFP4 fused to a human CD8 transmembrane domain and intracellular 2x mTurquoise2. Endogenously tagged EGL-20::YPET::3xFlag is efficiently sequestered by the Morphotrap transgene (the transgene functions as expected for Wnt), leading to Q neuroblast migration defects. NOTE: cpIs158/Morphotrap does not capture all YPET-tagged extracellular proteins, so sequestration should be determined empirically. cpIs130 is a single copy transgene expressing a 2x mKate2::PH membrane marker in seam cells, Q neuroblasts, and many hypodermal cells, and HisCl1 expression from the tag-168 upstream intergenic sequence. Expression of HisCl1 from the single copy insertion does not appear to be sufficient for immobilizing animals. cpIs158 was inserted at Chr I:2851088 near ttTi4348 using Cas9-triggered homologous recombination. cpIs130 was inserted at Chr II:8420157-8420243 near ttTi5605.
