Abstract

Cuticle formation and molting are critical for the development of Caenorhabditis elegans. To understand cuticle formation more clearly, we screened for suppressors in transgenic worms that expressed dominant ROL-6 collagen proteins. The suro-1 mutant, which is mild dumpy, exhibited a different ROL-6::GFP localization pattern compared to other Dpy mutants. We identified mutations in three suro-1 mutants, and found that suro-1 (ORF R11A5.7) encodes a putative zinc-carboxypeptidase homologue. The expression of this enzyme in the hypodermis and the genetic interactions between this enzyme and other collagen-modifying enzyme mutants suggest a regulatory role in collagen processing and cuticle organization for this novel carboxypeptidase. These findings aid our understanding of cuticle formation during worm development.
