获得了一个U937细胞亚系(U937 D),其中存在肌酸激酶B(CK-B)信使RNA并与核糖体结合,但未检测到CK活性。用含有CK-B信使RNA 3′非翻译区(3′ UTR)的逆转录病毒载体转化U937 D细胞,表现出CK活性,而CK-B mRNA丰度无变化。该3′ UTR在体外与野生型细胞的S100提取物组分形成复合物。在用含3′ UTR的载体转化后表达CK活性的细胞的S100提取物中未检测到这种结合活性。这些结果表明,CK-B的翻译被一个或多个可溶性因子与3′ UTR的结合所抑制。
A subline of U937 cells (U937D) was obtained in which creatine kinase B (CK-B) messenger RNA was present and bound to ribosomes, but CK activity was undetectable. Transformation of U937D cells with retrovirus vectors that contain the 3′ untranslated region (3′ UTR) of CK-B messenger RNA exhibited CK activity with no change in abundance of CK-B mRNA. The 3′ UTR formed a complex in vitro with a component of S100 extracts from wild-type cells. This binding activity was not detectable in S100 extracts from cells that expressed CK activity after transformation with the 3′ UTR-containing vector. These results suggest that translation of CK-B is repressed by binding of a soluble factor or factors to the 3′ UTR.
