DHX29 Reveals Hidden Layer of Gene Regulation Tied to Codon Choice
Scientists identified DHX29 as a key regulator that senses non-optimal codons during translation, binding to ribosomes decoding these codons and recruiting the GIGYF2•4EHP complex to suppress certain mRNAs. This reveals a second regulatory layer in the genetic code that links synonymous codon choice to gene expression and may influence development and disease.
