乳头瘤病毒 E7 蛋白可能在肿瘤发生中发挥重要作用,因为它是人类宫颈癌衍生细胞系中存在的主要病毒蛋白。由于棉尾兔乳头瘤病毒 (CRPV) 系统与病毒诱发的恶性肿瘤研究的相关性,我们表征了其由异源强启动子表达的 E7 蛋白。用含有 E7 88 个羧基端氨基酸的 Trp E-E7 融合蛋白免疫兔子获得 E7 特异性抗血清。该抗血清特异性地从[35]S]半胱氨酸中沉淀出来,而不是从32PO4标记的瞬时转染的COS-7细胞中的14-kDa蛋白中沉淀出来。该蛋白质仅存在于可溶性细胞质部分中,并且在非变性甘油梯度中表现出不均匀的沉降速率。
The papillomavirus E7 protein may play an important role in oncogenesis as it is the major viral protein present in human cervical cancer-derived cell lines. Because of the relevance of the cottontail rabbit papillomavirus (CRPV) system for the study of viral-induced malignancies, we characterized its E7 protein expressed by a heterologous strong promoter. An E7-specific antiserum was obtained by immunizing rabbits with a Trp E-E7 fusion protein containing the 88 carboxyl-terminal amino acids of E7. This antiserum specifically precipitated from [35]S]cysteine but not from32PO4-labeled transiently transfected COS-7 cells a 14-kDa protein. The protein was present only in the soluble cytoplasmic fraction and exhibited a heterogeneous sedimentation rate in nondenaturing glycerol gradients.
