T1 基因被 Ha-ras (EJ) 或 v-mos 癌蛋白以及 NIH3T3 成纤维细胞中的有丝分裂原瞬时激活。其 337 个氨基酸 (38 kDa) 的主要基因产物经历了广泛的翻译后修饰。对于生化分析,T1 基因产物在痘苗病毒系统中过度表达。感染重组 T1 牛痘病毒的细胞产生并分泌多种 60-70 kDa 的蛋白质,这些蛋白质与针对两种 T1 特异性肽产生的多克隆抗血清发生反应。两条证据表明,T1 蛋白的表观大小异质性是由于总分子质量的 40-50% 的可变碳水化合物含量造成的。首先,在 N-糖基化抑制剂(衣霉素)存在的情况下,T1 痘苗病毒感染细胞中的抗血清检测到单个 38-kDa 蛋白质。其次,糖苷酶消化表明 T1 蛋白成熟涉及糖基化和唾液酸化。这些翻译后修饰步骤在不同类型的细胞中似乎相似。
The T1 gene is transiently activated by the Ha-ras (EJ) or v-mos oncoproteins and by mitogens in NIH3T3 fibroblasts. Its primary gene product of 337 amino acids (38 kDa) undergoes extensive post-translational modification. For biochemical analysis, the T1 gene product was over-expressed in a vaccinia virus system. Cells infected with a recombinant T1-vaccinia virus produce and secrete multiple proteins of 60-70 kDa which react with polyclonal antisera raised against two T1-specific peptides. Two lines of evidence suggest that the apparent size heterogeneity of the T1 protein is due to a variable carbohydrate content of 40-50% of the total molecular mass. First, in the presence of an inhibitor of N-glycosylation (tunicamycin), a single 38-kDa protein is detected by the antisera in the cells infected with T1-vaccinia virus. Second, glycosidase digestions show that T1 protein maturation involves glycosylation and sialylation. These post-translational modification steps appear to be similar in different types of cells.
