Low penetrance (about 25%) embryonic lethality and reduced brood size. wsp-1(gm324) is an N-terminal deletion that exhibits no observable mRNA or protein.

xnIs506 [cdc42p::GST::GFP::wsp-1(GBD) + unc-119(+)]. Biosensor for active CDC-42. In epithelia, GFP is enriched at junctions between epithelial cells. Some signal is in the nucleus (this signal is reduced by addition of GST, which makes the transgenic protein larger). Reference: Zilberman, Y., J. Abrams, D.C. Anderson, and J. Nance. 2017. Cdc42 regulates junctional actin but not cell polarization in the Caenorhabditis elegans epidermis. J Cell Biol 216: 3729-3744.

Constructed by crossing individual fluorescence knock-in worms. TagRFP inserted into the endogenous arx-2 gene at its C-terminus and GFP inserted into the endogenous wsp-1a gene at its N-terminus by Cas9-triggered homologous recombination.

ojIs40 [wsp-1(G-protein-Binding-Domain)::GFP + unc-119(+)]. Maintain under normal condition. Reference: Kumfer et al. (2010) Mol Bio Cell21(2):266-77.

ojIs40 [wsp-1(G-protein-Binding-Domain)::GFP + unc-119(+)]. Maintain under normal conditions. Heterozygotes are WT, and segregate WT, occasional Dpy (non-let recombinant sC1 homozygotes), and nearly sterile tm1909 homozygotes. Pick WT and check for correct segregation of progeny to maintain.
