Abstract
A free cytoplasmic 22 S ribonucleoprotein particle exhibiting a major template activity in rabbit reticulocyte system has been identified in the cryptobiotic gastrulae of Artemia salina. This particle contains non-polyadenylated 9 S messenger RNA which codes primarily for a non-histone basic protein with an apparent molecular weight of 26 000 daltons. We have previously demonstrated the presence of a translational inhibitor RNA which is apparently responsible for transforming polyadenylated messenger (Slegers et al., FEBS Letters 80, 390-394, 1977). This inhibitor RNA was found to be completely ineffective on the template activity of non-polyadenylated 22 S messenger ribonucleoprotein, confirming the specificity of this regulatory RNA for polyadenylate sequences.
摘要
在卤虫隐生胚囊中已鉴定出一种游离的细胞质22S核糖核蛋白颗粒，它在兔网织红细胞系统中表现出主要的模板活性。该颗粒含有非聚腺苷酸化的9S信使RNA，其主要编码一种表观分子量为26000道尔顿的非组蛋白碱性蛋白。我们之前已证明存在一种翻译抑制RNA，它显然负责转化聚腺苷酸化信使（斯莱格斯等人，《欧洲生物化学学会联合会快报》80，390 - 394，1977）。发现这种抑制RNA对非聚腺苷酸化的22S信使核糖核蛋白的模板活性完全无效，这证实了这种调节RNA对聚腺苷酸序列的特异性。
