From modular engineering to practical applications: Advances in GPCR-based yeast biosensors.

Engineered GPCR-based yeast biosensors have achieved significant performance improvements, enabling diverse practical applications through modular design and optimization.

• Why it matters: GPCRs are essential for sensitive and specific biosensing, but translating their potential into practical tools requires systematic engineering and optimization to overcome existing limitations.
• What they did: The study reviews engineering strategies applied to core modules—sensing, transduction, and output—using a modular framework, and discusses how these modifications improve biosensor performance.
• The result: Enhanced biosensors now serve a broad range of applications, and integrating AI and synthetic biology promises to enable predictive, programmable design of future-generation biosensors.
