AA278 C. elegans dhIs59. Show Description
dhIs59 [Topo::daf-9::GFP + lin-15(+)]. Perinuclear expression in a ventral pair of bilateral neurons identified as the IL1Vs or URAVs in the anterior ganglia. By mid-L2, expression in the cytoplasm of the hypodermis, the syncitial epidermis, but absent from midline, epidermal seam cells. Levels peak around the L2 molt and diminish during L4.

ABR212 C. elegans acd-1(sta6) delm-2(ok1822) I. Show Description
acd-1 and delm-2 are tandem paralogs. This double mutant was created by CRISPR-engineered deletion of acd-1 in a delm-2(ok1822) background (parental strain RB1523). acd-1(sta6) is predicted to be a null allele (~200bp indel causing frameshift in exon 4).
ABR225 C. elegans acd-1(sta6) delm-2(ok1822) I; delm-1(ok1266) IV. Show Description
acd-1 and delm-2 are tandem paralogs. This double mutant was created by CRISPR-engineered deletion of acd-1 in a delm-2(ok1822) background (parental strain RB1523). acd-1(sta6) is predicted to be a null allele (~200bp indel causing frameshift in exon 4). This triple mutant strain was made by crossing the acd-1(sta6) delm-2(ok1822) double mutant with delm-1(ok1226) parental strain RB1177.
AFS205 C. elegans zen-4(cle5) IV. Show Description
Temperature-sensitive embryonic-lethal mutant. Maintain at 15C. Shift L4s to 25C overnight to observe mutant phenotype of embryos produced by adults. Mutants lack a central spindle during early embryonic mitosis and exhibits a late cytokinesis defect (cleavage furrows regress after ingressing in nearly to the center of dividing embryonic cells). This strain can be used for CRISPR-Cas9 co-conversion. There is a causal mis-sense mutation present in zen-4(cle5), GAC to AAC (D520N), and one silent mutation, GCA to GCT at codon 519, that introduces an AluI site for RFLP analysis. A previous deposited version of this strain, zen-4(ok153), possessed two mis-sense mutations: GAC to AAC (D520N) and GAT to AAT (D735N). Reference: Farboud B, et al. Genetics Early online November 30, 2018; https://doi.org/10.1534/genetics.118.301775.
AFS222 C. elegans zen-4(cle10) IV. Show Description
Temperature-sensitive embryonic-lethal mutant. Maintain at 15C. Shift L4s to 25C overnight to observe mutant phenotype of embryos produced by adults. Mutants lack a central spindle during early embryonic mitosis and exhibits a late cytokinesis defect (cleavage furrows regress after ingressing in nearly to the center of dividing embryonic cells). This strain can be used for CRISPR-Cas9 co-conversion. There is a causal mis-sense mutation present in zen-4(cle10), GAC to AAC (D520N), and two silent mutations. One silent mutation is a CGA to CGG mutation at codon 523 that creates a recognition site for a Cas9 guide RNA, in order to use zen-4(cle10ts) as a CRISPR/Cas9 co-conversion marker. The other silent mutation is a GCA to GCT mutation at codon 519 that introduces an AluI site for RFLP analysis. Reference: Farboud B, et al. Genetics Early online November 30, 2018; https://doi.org/10.1534/genetics.118.301775.

BOX215 C. elegans erm-1(mib16[erm-1[T544D]::GFP]) I. Show Description
Homozygous viable. Endogenous erm-1 locus tagged with eGFP and modified to mimic ERM-1(T544) phosphorylation. Variant affects ERM-1 localization and dynamics. Reduced brood size, increased embryonic and larval lethality. eGFP-tagged ERM-1 is not fully functional: animals have a reduced brood size and incomplete outgrowth of the excretory canal, but show no other developmental or morphological abnormalities. The penetrance of intestinal phenotypes is slightly higher than in untagged T544 mutants, presumably owing to a detrimental influence of the COOH-terminal GFP tag. Reference: Ramalho JJ, et al. Development. 2020 Jul 22;147(14):dev188011. PMID: 32586975
