The Structure and Function of tmRNA
tmRNA的结构与功能The Structure and Function of tmRNA

tmRNA is a dual small RNA similar to a tRNA and a mRNA which plays an important role in an unusual mode of translation-trans translation. Recently, it was found that tmRNA had something to do with regulating gene expression and cell cycle. So the researchers have paid much attention on such area. Furthermore, it is an im- portant part in RNomics era. This article reviews the progress about the structure and function of tmRNA in recent years.
