LIN-35

CELE_C32F10.2, C32F10.2
lin-35 encodes the C. elegans retinoblastoma protein (Rb) ortholog; lin-35 was first identified in screens for synthetic multivulva (synMuv) genes and as a class B synMuv gene, functions redundantly with class A genes to antagonize Ras signaling and negatively regulate vulval development; in addition, loss of lin-35 activity results in enhanced RNA interference; lin-35 activity is also required redundantly with: 1) pha-1 and ubc-18 for early steps in pharyngeal morphogenesis, 2) fzr-1 for normal patterns of postembryonic proliferation, 3) xnp-1 for somatic gonad development, and 4) psa-1 for fertility and embryonic and larval development; on its own, lin-35 is also required for wild-type levels of fertility; LIN-35 is expressed broadly in embryos and L1 larvae, but in later larvae and adults is detected in vulval precursor cells and their descendants as well as a subset of head and tail cells.
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.
