Analysis of dominant mutations affecting muscle excitation in Caenorhabditis elegans.

Abstract excerpt

We examined mutations that disrupt muscle activation in Caenorhabditis elegans. Fifteen of 17 of these genes were identified previously and we describe new mutations in three of them. We also describe mutations in two new genes, exp-3 and exp-4. We assessed the degree of defect in pharyngeal, body-wall, egg-laying, and enteric muscle activation in animals mutant for each gene. Mutations in all 17 genes are...
