Regulation of tissue-specific expression of the esterase S gene in Drosophila virilis.


The esterase S gene (estS) of Drosophila virilis is specifically expressed in the ejaculatory bulbs of males. Its sequencing shows similarities between estS product and other esterases of different origin. The transcription of estS in ejaculatory bulbs is at least 2 orders of magnitude higher than in other tissues of males. Two promoters, P1 (distal) and P2… (More)
