Abstract
The sevenless gene of Drosophila melanogaster encodes a transmembrane tyrosine kinase receptor required for normal eye development. We report here the isolation and DNA sequence analysis of the sevenless gene from Drosophila virilis. The predicted amino acid sequences of the sevenless proteins from these two species, which diverged approximately 60 million years ago, are compared.
摘要
黑腹果蝇的无七基因编码一种正常眼睛发育所需的跨膜酪氨酸激酶受体。我们在此报告从粗壮果蝇中分离出无七基因并进行DNA序列分析的情况。对这两个大约在6000万年前分化的物种的无七蛋白的预测氨基酸序列进行了比较。
