Transfer RNA (tRNA) helps translate messenger RNA into proteins by carrying amino acids to the ribosome. Researchers have discovered that modifying tRNA through editing or altering its structure can influence the genetic code and protein synthesis. Precisely regulating tRNA may help treat diseases but also needs careful study to avoid unintended consequences.

- Figure 1. Tinkering with Transfer RNA. Type 2 diabetes is associated with variant CDKAL1 . Wei et al. 4 recently ascribed a function to this gene: it critically modifies a specific transfer RNA (tRNA) by catalyzing the addition of a methyl–thio moiety (ms 2 t 6 ) to a residue adjacent to the anticodon (in pink). Mice deficient in beta-cell Cdkal1 incorporate fewer lysine residues into proinsulin, which may contribute to the susceptibility of these mice to type 2 diabetes.
