Dear Donu,
Thank you for reporting this issue.
The promoter you are looking for can be found under the name ITBX_1, see
This is a nomenclature issue. Your gene of interest is known under different names. The name ITBX is used by UniProt and probably relates to the protein name "Integrin beta-PS", see
https://www.uniprot.org/uniprotkb/P11584/
I found this promoter by clicking on the link "EPD viewer" on the EPD Drosophila home page:
Once connected ti the UCSC genome browser, type" mys" into the search window. A list if gene/transcript names/IDs will appear. Just click on one of them to return to the browser's visual interface.
I hope this was helpful,
