[The study of interaction between paralogous tandem repeats stellate and suppressor of stellate in the genome of Drosophila melanogaster].
Testis-specific expression of tandemly repeated Stellate genes, located in eu- and heterochromatin regions of the X chromosome of Drosophila melanogaster, is suppressed by homologous Suppressor of Stellate repeats located on the Y chromosome. Using transgenic lines, we have demonstrated that three Su(Ste) copies failed to change the expression of the reporter construction carrying the bacterial beta-galactosidase gene under control of the Stellate gene regulatory sequence. Possible mechanisms of the Su(Ste) repeat suppressor activity are discussed.
