[Role of the "enhancer of yellow" genes in the regulation of expression of the "yellow" gene in Drosophila melanogaster].

Abstract excerpt

The e(y)1/TAFII40, e(y)2 and e(y)3 genes encode general transcription factors in Drosophila melanogaster. Weak mutations in e(y)1u1, e(y)2u1 and e(y)3u1 regulate enhancer-dependent transcription of the yellow gene in bristles similarly, even if it is activated by a non-yellow specific enhancer element. At the same time, these mutations do not affect yellow expression in the body and wings. We found genetic data...
