Research from Kyoto University claims that cells can recognize inefficient genetic instructions and basically silence them. The protein DHX29 plays a fundamental part in this research. DHX29 identifies and silences inefficient messages. The research from scientists at Kyoto University showed that the protein recognizes weaker messages when it is physically interacting with the 80S ribosome. Once it notices the weak message, it uses another protein called GIGYF2•4EHP to specifically suppress that mRNA, and therefore, halting that gene's output. This research suggests that our DNA does not simply control which genes go on and off, but how the particular makeup of those genes affect their endpoint overall. This could lead to the understanding of how “silent” mutations disrupt expression and contribute to diseases.
