Tissue localization and synthesis of PEB (the major protein of ejaculatory bulb (EB) in D. melanogaster) were studied. PEB and its minor form hPEB were detected only in EB as shown by immunoblotting technique. Transplantation of genital imaginal disks and the EBs of young males into recipients of strain with different PEB electrophoretic mobility showed that synthesis and accumulation of PEB do not depend on EB interaction with other organs. In genotypic females transformed into males and intersexes by sex-reversing mutations PEB was detected in EB but not in other organs.
