KSR-1

CELE_F13B9.5, sur-3, sar-2, F13B9.5
ksr-1 encodes one of two C. elegans Kinase Suppressor of Ras paralogs; during development, ksr-1 functions singly to control sex myoblast migration and redundantly with ksr-2 to control development of the vulva, excretory system, and male spicules; as ksr-2; ksr-1 doubly mutant animals have severely reduced or absent MPK-1/ERK diphosphorylation levels in somatic tissue, KSR-2 and KSR-1 likely function to positively regulate signaling through the LET-60/Ras pathway; genetic analyses have identified a number of ekl (enhancer of ksr-1 lethality ) mutations that, in combination with a ksr-1 null mutation, result in defects in excretory duct cell fate specification accompanied by larval lethality; the ekl mutations identified gene products that are maternally required for duct cell fate specification and encode proteins likely to be involved in transcriptional and post-transcriptional gene regulation.

LET-60

CELE_ZK792.6, lin-34, ZK792.6
let-60 encodes a member of the GTP-binding RAS protooncogene family; let-60 activity is required for viability, vulval development, spicule development, germ line meiotic progression, posterior development of the hypodermis, chemotaxis, sex myoblast migration, and muscle membrane extension; let-60 acts genetically downstream of let-23 with respect to vulval development and upstream of the MAPK pathway with respect to chemotaxis; let-60 is expressed in neural, muscle, and hypodermal lineages.

Phenotypic Enhancement

A genetic interaction is inferred when mutation or overexpression of one gene results in enhancement of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

Systematic mapping of genetic interactions in Caenorhabditis elegans identifies common modifiers of diverse signaling pathways.

Lehner B, Crombie C, Tischler J, Fortunato A, Fraser AG

Most heritable traits, including disease susceptibility, are affected by interactions between multiple genes. However, we understand little about how genes interact because very few possible genetic interactions have been explored experimentally. We have used RNA interference in Caenorhabditis elegans to systematically test approximately 65,000 pairs of genes for their ability to interact genetically. We identify approximately 350 genetic interactions between ... [more]

Ontology Terms

  • phenotype: larval lethal (WBPHENOTYPE:0000054)

Additional Notes

  • A large-scale genetic interaction analysis was carried out to detect interactions between 37 query mutants and approximately 1,750 target genes compromised by RNA interference (RNAi). Interactions were identified if the phenotype of the combined query-target perturbation was greater than the sum of the two individual perturbations.

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.
