Single-minded (sim) is a master regulatory gene that directs differentiationin the central nervous system during Drosophilaembryogenesis. Recent identification of the mesectoderm enhancer(MSE) of sim has led to the hypothesis that two Snail(Sna)-binding sites in the MSE may repress sim expression inthe presumptive mesoderm. We provide evidence here thatthree Sna-binding sites proximal... https://allfixelectricales.shop/product-category/phone-adaptor-kit/
