Sevenless (sev) 基因决定果蝇眼睛中单一感光细胞类型的命运。它编码与酪氨酸激酶同源的假定细胞表面蛋白。在这里,我们确定了 sev 基因的完整结构,并证明 sev 蛋白在这一发育决策中的作用关键取决于酪氨酸激酶功能。与其他已知的酪氨酸激酶相比,sev基因产物在大小和结构上是独特的。它是一种由 2554 个氨基酸组成的多肽,具有两个假定的跨膜片段。假定激酶结构域的 ATP 结合位点中的单个氨基酸取代会导致合成无活性的 sev 蛋白,无法决定细胞命运。
The sevenless (sev) gene determines the fate of a single photoreceptor cell type in the eye of Drosophila. It encodes a putative cell-surface protein with homology to tyrosine kinases. Here we have determined the complete structure of the sev gene and have demonstrated that the role of the sev protein in this developmental decision is critically dependent on the tyrosine kinase function. In comparison with other known tyrosine kinases, the sev gene product is unique in size and structure. It is a polypeptide of 2554 amino acids with two putative transmembrane segments. A single amino acid substitution in the ATPbinding site of the putative kinase domain results in the synthesis of an inactive sev protein unable to determine cell fate.
