DUP237 C. elegans glh-1(sam140[glh-1::T2A::wrmScarlet(1-10)]) I. Show Description
T2A::wrmScarlet(1-10) fused to the C-terminus of endogenous GLH-1. The T2A self-cleaving peptide separates wrmScarlet(1-10) from GLH-1 post-translationally so that wrmScarlet(1-10) disperses throughout germ cell nuclei and cytoplasm. wrmScarlet(1-10) is also maternally loaded into embryos, where it persists through early and mid-embryonic development. Proteins tagged with the 18aa wrmScarlet(11) sequence will bind wrmScarlet(1-10) in the germline and early embryo to emit wrmScarlet fluorescence. Broods from DUP237 are similar to wild-type at permissive and restrictive temperatures. Transgene tag was inserted by CRISPR/Cas9 in an N2 background. Reference: Goudeau J, et al. Genetics. 2021 Apr; 217(4): iyab014. PMID: 33693628.

Knock-in into previously modified unc-119(ox819) endogenous locus. Cas9 insertion marked with myo-2p::cyOFP (cyan-excitable Orange Fluorescent Protein), a long-Stokes-shift fluorescent protein that is spectrally separable from common green and red fluorophores.
