KX10 C. elegans ife-3(ok191)/unc-34(e566) V. Show Description
At 20C heterozygotes segregate WT heterozygotes, Unc unc-34(e566) homozygotes, and Mog ife-3(ok191) homozygotes. At 25C ife-3(ok191) homozygotes are not always Mog, but progeny of the non-Mog homozygotes are embryonic lethal. Deletion of 686 bp from ife-3 removes proximal promoter and all of exon 1. Breakpoint determined by B. Keiper is: taattttcatattttccgct/tatcta/ttatcgattttttccagatg. Eukaryotic translation initiation factor 4E (eIF4E) gene (isoform 3; B0348.6); paralog of human eIF4E isoform.
JK6594 C. elegans ife-3(q1259[1xV5::ife-3]) V. Show Description
1xV5 tag inserted at N-teminus of endogenous ife-3 locus. Generated in N2 background. Reference: Carrick BH, et al. Dev Cell. 2024 Mar 11;59(5):661-675.e7. doi: 10.1016/j.devcel.2024.01.005. PMID: 38290520.
KX155 C. elegans ife-1(eu20[mKate2:Myc3x:ife-1]) III, ife-3(eu21[GFP::Flag3x::ife-3]) V Show Description
In-frame CRISPR/Cas9 fusions into the genes encoding the eIF4E paralogs IFE-1 and IFE-3. Red and Green fluorescence, respectively. Strong fluorescence for both in the hermaphrodite and male gonads, but with distinct expression character and germ granule association. Germ cell cytoplasmic expression and lesser somatic expression are also observed. Both insertions are homozygous by PCR confirmation.
SHG682 C. elegans ife-3(ust639[ife-3::GFP::3xFlag]) V. Show Description
GFP::3xFlag inserted into endogenous ife-3 locus using CRISPR/CAS9 engineering. Reference: Zeng C, et al. Cell Rep. 2019 Jun 18;27(12):3561-3572.e3. doi: 10.1016/j.celrep.2019.05.076. PMID: 31216475.
