|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.
