Abstract

We have determined the complete nucleotide sequence of a human DNA fragment of approximately 13 kbp, which was shown by Southern blot analysis to contain the entire v-fes/fps cellular homolog. The v-fes/fps homologous sequences were dispersed over 11 kbp in 18 interspersed segments which were flanked by splice junctions. Fusion of these segments created a DNA fragment in which coding regions similar to those observed in the viral oncogenes v-fes of the Gardner-Arnstein (GA) and Snyder-Theilen (ST) strains of feline sarcoma virus and v-fps found in Fujinami sarcoma virus could be identified. A potential initiation site in the first exon was found. About 200 nucleotides downstream of a translational stop codon in the v-fes/fps homologous region, a poly(A) addition signal was identified. The deduced amino acid sequence has a molecular weight of 93 390 dalton resembling NCP92, the recently described human c-fes/fps product. The topography of human c-fes/fps appeared to resemble that of chicken c-fps.

摘要

我们已经确定了一段约13kbp的人类DNA片段的完整核苷酸序列,Southern印迹分析表明该片段包含整个v-fes/fps细胞同源物。v-fes/fps同源序列分散在11kbp的18个散布片段中,这些片段两侧为剪接连接点。这些片段的融合产生了一个DNA片段,其中可以鉴定出与在猫肉瘤病毒的Gardner-Arnstein(GA)和Snyder-Theilen(ST)株的病毒癌基因v-fes以及在藤浪肉瘤病毒中发现的v-fps中观察到的编码区域相似的编码区域。在第一个外显子中发现了一个潜在的起始位点。在v-fes/fps同源区域的翻译终止密码子下游约200个核苷酸处,鉴定出一个聚腺苷酸添加信号。推导的氨基酸序列的分子量为93390道尔顿,类似于最近描述的人类c-fes/fps产物NCP92。人类c-fes/fps的拓扑结构似乎类似于鸡c-fps的拓扑结构。
