Abstract

A factor from rabbit-reticulocyte ribosome, which stimulates by 5-fold initiation of hemoglobin mRNA translation in Krebs ascites cell extracts, was purified to homogeneity. The factor, a protein of about 65,000 molecular weight in sodium dodecyl sulfate, discriminates between various mRNAs: it stimulates translation of alpha globin mRNA and of tobacco mosaic virus RNA, but has only a small effect on beta globin mRNA and no effect at all on Mengo virus RNA translation.

摘要

一种来自兔网织红细胞核糖体的因子,它能使克雷布斯腹水细胞提取物中血红蛋白mRNA的翻译起始提高5倍,该因子已被纯化至同质。该因子在十二烷基硫酸钠中是一种分子量约为65,000的蛋白质,它能区分各种mRNA:它能刺激α-珠蛋白mRNA和烟草花叶病毒RNA的翻译,但对β-珠蛋白mRNA的影响很小,对门戈病毒RNA的翻译则完全没有影响。
