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.

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.

EU554 C. elegans zen-4(or153) IV. Show Description
Temperature sensitive. Grow at permissive temperature of 15C. Fully penetrant cytokinesis defect at the restrictive temperature of 25C.
EU716 C. elegans zen-4(or153) IV. Show Description
Temperature-sensitive, embryonic-lethal mutant that lacks 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). About 100% of embryos produced by homozygous mothers hatch at 15C; 0% hatch at 26C. ZEN-4 = vertebrate MKLP1 kinesin. There are two mis-sense mutations present in zen-4(or153). One is a D520N (GAC to AAC) and the other is D735N (GAT to AAT). Whether one or both is responsible for the phenotype is not know. Maintain at 15C. Shift L4s to 26 overnight to observe mutant phenotype on embyros produced by adults.
MG170 C. elegans zen-4(or153) IV; xsEx6. Show Description
xsEx6 [zen-4::GFP + rol-6(su1006)]. Maintain at 25C. Rollers.
EU591 C. elegans dpy-13(e184) zen-4(or153) IV. Show Description

EU592 C. elegans unc-8(n491) zen-4(or153) IV. Show Description
