Genetic mapping information
Comments

proximal to -15 kb Position of 3R breakpoint. Origin (coordinate 0) is the first EcoR1 site to right of the genomic fragment homologous to the cDNA clone 126 D12 used to start the E(spl) chromosomal walk, '+' values to the right, '-' values to the left (Knust et al., EMBO J. 1987)

Comments on Cytology

Limits of break 1 from complementation mapping against E(spl) (citation unavailable) Limits of break 2 from polytene analysis (citation unavailable) Limits of break 3 from polytene analysis (citation unavailable)

Affected Genes Inferred by Location (0)
    If no genes are listed here, it may be because the affected region is very large. The JBrowse insert above may show an error for the same reason, and other FlyBase tools such as CytoSearch may also fail for large regions. You can contact FlyBase for more help.
    In these cases, there will be no "Export to Hitlist" button to the left.
