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.
Caenorhabditis elegans

Negative Genetic

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.

BACKGROUND: Understanding gene function and genetic relationships is fundamental to our efforts to better understand biological systems. Previous studies systematically describing genetic interactions on a global scale have either focused on core biological processes in protozoans or surveyed catastrophic interactions in metazoans. Here, we describe a reliable high-throughput approach capable of revealing both weak and strong genetic interactions in the ... [more]

Additional Notes

  • A systematic genetic interaction analysis (SGI) was carried out to detect interactions between 11 query mutants and 858 target genes compromised by RNA interference (RNAi). Interactions were determined using growth scores that indicated whether the resulting number of progeny from the double mutant was significantly different than that of single mutant controls.
