[Mapping of the gene coding for the major protein of the ejaculatory bulb in Drosophila melanogaster]

The major protein of ejaculatory bulb of Drosophila melanogaster males (PEB-me) is represented by a group of 4-5 sufbractions. Four PEB variants differing in SDS-PAGE mobility were found. The results of genetic analysis suggest that electrophoretic mobility of the entire complex of protein PEB bands is controlled by a single locus (peb). The locus is therefore supposed to contain the structural gene for the subfractions of PEB. Its genetic and cytological location is 2-107.2-2-108.0 and 60E11-60F5, respectively.
