摘要: Sucrose gradient and Northern analyses were used to study the translational status of endogenous multiple mRNAs encoding prepropeptide for human insulin-like growth factor II. The results showed that a minor 4.8-kilobase mRNA was exclusively engaged in synthesis on membrane-bound polysomes, whereas major 6.0-kilobase present cytoplasmic particle which stable EDTA. We conclude discrimination between is dictated by their different 5'-untranslated regions.
