Chemical identifiers and library names are reproduced from ChemGrid records. Missing values are omitted.
Measured chemical–genetic activity
24 measurements across 24 distinct library–species–strain assays; 0 assays have at least one significant response (|Z| ≥ 4, p ≤ 0.001, excluding flagged outliers).
Responses are indirect screening phenotypes. They do not establish that a strain gene is a direct molecular target. Strains and timepoints are retained as recorded; these counts are not counts of unique ORFs.
Recorded target evidence and yeast matches
Source annotations are shown separately from SONAR hypotheses. Evidence type and identity matching can vary; consult the linked source and interactive evidence panel.
| Target | Source | Yeast ORF / orthologue |

Structural activity predictions and SONAR
Stored structural activity predictions are available in the interactive profile, with assay-specific cutoffs and applicability-domain assessments.
SONAR ranks candidate targets through genetic and physical interaction evidence. Structural SONAR uses predicted strain responses; measured SONAR uses experimental responses. These are experimental hypotheses, not confirmed binding targets. Outside-domain predictions are treated as unknown.
