A mutation at the start codon defines the differential requirement of dpy-11 in Caenorhabditis elegans body hypodermis and male tail.

Abstract excerpt

dpy-11 encodes a thioredoxin-like molecule that is important for both body and male sensory ray morphogenesis in Caenorhabditis elegans. A mutant allele, s287, has a point mutation with its start codon, AUG, converted into AUA, presumably leading to null function. Since only a weak loss-of-function phenotype was observed, we tested whether an alternative start codon or the converted AUA could be used for...
