摘要：

The control of translation is a critical aspect of gene regulation. It is often inversely related to mRNA degradation and is typically controlled during initiation. The Stm1 protein in Saccharomyces cerevisiae has been shown to interact with ribosomes, affect the interaction of eEF3 with ribosomes, and promote the decapping of a subclass of mRNAs. We demonstrate that in vitro Stm1 inhibits translation after formation of an 80S complex. This suggests that Stm1 modulates translation and mRNA decapping by controlling translation elongation.
