Programming the translational landscape for predictable gene expression.

Translation engineering enables precise control of gene expression by modulating initiation, elongation, and termination phases, crucial for synthetic biology applications.

• Why it matters: Achieving predictable gene expression is essential for advancing biomanufacturing and medicine, yet current methods often rely on trial-and-error tuning, limiting reliability and efficiency.
• What they did: The review examines how 5'-UTR architecture, mRNA folding, codon optimization, ribosome-stalling, stop-codon readthrough, and mRNA decay influence translation, emphasizing a shift toward rational design.
• The result: This approach offers a roadmap for designing sophisticated translational landscapes, facilitating the development of tailored biological systems for smart biomanufacturing and precision medicine.
