SEM-5

CELE_C14F5.5, C14F5.5
sem-5 encodes a Src homology (SH) domain 2 and 3-containing protein, orthologous to human GRB2 (OMIM:108355) and Drosophila Drk; sem-5 functions in multiple signaling pathways during development including those regulating sex myoblast migration, muscle membrane extension, vulval induction, fluid balance, viability, and formation of the male tail; SEM-5 acts downstream of the LET-23 epidermal growth factor receptor to negatively regulate RAS-, MAP-, and IP-3-, mediated signal transduction; a sem-5::yfp promoter fusion is expressed in many cells throughout development, including the hypodermis, intestine, neurons, body wall muscles, and vulval precursor cells.

SDZ-23

CELE_F58G4.4, F58G4.4
sdz-23 encodes a putatively secreted protein with a single EGF domain, with some similarity to LAG-2; sdz-23 begins to be expressed in the E blastomere of 8-cell embryos, and continues to be expressed solely in the E lineage througout embryogenesis; sdz-23 requires SKN-1 and WRM-1 for E lineage expression, and is a putative MED-1/2 target gene; sdz-23 is both activated by POP-1 (with SYS-1 as coactivator, in the E lineage) and repressed by POP-1 (in the MS lineage), while the dependence of sdz-23 on WRM-1 for E lineage expression is alleviated by loss of POP-1, indicating that WRM-1 switches POP-1 from repression to activation in the E lineage; sdz-23 requires SYS-1 for normal embryonic expression; SDZ-23 has no obvious function in mass RNAi assays.

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.
