drIs4 [gpdh-1p::GFP + col-12p::DsRed] IV. K957M mutation introduced into the endogenous ogt-1 locus using CRISPR/Cas9; Sanger sequence confirmed. The K957M mutation ablates the O-GlcNAcylation activity of OGT-1 as measured by the RL2 O-GlcNAc antibody. gpdh-1p::GFP reporter is induced in the hypodermis and intestines during hypertonic stress. col-12p::GFP is constitutively expressed in the hypodermis. Reference: Urso SJ, et al. (2020). The O-GlcNAc transferase OGT is a conserved and essential regulator of the cellular and organismal response to hypertonic stress. bioRxiv, 2020.2005.2001.072033.
