  • Nearby genes listed are only those in which the transcription start site, or a predicted transcription start site, resides within 10 kb of the P-element insert according to FlyBase. `None' indicates absence of genes within 10 kb of the P-element insert site. `Upstream' and `downstream' denote the location of the P-element with respect to the gene. `∼' indicates lines in which the number of lac repeats were estimated based on the size of the lac repeat-containing fragment.
