- A major challenge in NT structural biology is obtaining pure, stable, and high-quality native protein.
Purpose of the Study:
- To present a novel strategy for membrane protein expression and purification.
- To overcome the bottleneck in producing native nucleoside transporters for structural analysis.
- To provide a reference for investigating NTs and other membrane proteins.
Main Methods:
- Development of a high-yield membrane protein expression vector.
- Implementation of a rapid and efficient purification protocol for NTs.
- Focus on technical details of vector construction and optimization of expression and purification.
Main Results:
- Achieved improved time efficiency in protein production.
- Successfully generated high-quality, active, and stable membrane proteins.
- Demonstrated efficient use of reagents and consumables.
Conclusions:
- The novel strategy enhances the production of stable membrane proteins for structural studies.
- This approach facilitates the investigation of nucleoside transporter mechanisms.
- The reported methods can be applied to other membrane protein research.
