摘要在链脲佐菌素诱导的大鼠糖尿病模型中,我们发现了一个在骨骼肌中差异表达的新基因产物。Northern印迹分析显示,在所有研究组织中均有表达,在胰岛素敏感的组织(骨骼肌、心肌)中表达显著下调,但在胰岛素不敏感的脑中未见表达。序列分析显示,该基因有一个由58个氨基酸组成的开放阅读框,含有一个可能的跨膜结构域。我们将这种蛋白命名为DAPIT(胰岛素敏感组织中的糖尿病相关蛋白)。数据库搜索发现几个人、大鼠、小鼠、兔子、牛、马、猪、河豚和非洲爪哇EST在ORF中具有显著的同源性。DAPIT的氨基酸序列与果蝇的一种可能的蛋白质类似,也与一种从果肉中分离的产生aAMP的多肽相似。我们认为DAPIT是一种在脊椎动物和昆虫中高度保守的新蛋白。
Abstract We have identified a novel gene product differentially expressed in skeletal muscle in a rat diabetes model induced by streptozotocin. Northern blot analysis showed expression in all studied tissues and a marked down-regulation in insulin-sensitive tissues (skeletal muscle, myocardium) but not in insulin-insensitive brain. cDNA sequence analysis revealed an open reading frame (ORF) of 58 aminoacids, containing one putative transmembrane domain. We designated this protein DAPIT (diabetes-associated protein in insulin-sensitive tissues). Database searches discovered several human, rat, mouse, rabbit, bovine, equine, porcine, Fugu and Xenopus ESTs with significant homology in the ORF. The aminoacid sequence of DAPIT is similar to that of a putative protein of Drosophila melanogaster and to a aAMP-generating peptide isolated from the flesh by Neobellieria bullata. We propose that DAPIT is a novel protein that is highly conserved in vertebrates and insects.
