Summary
Comments and Discussion
- Can we identify a specific GPCR or class of GPCRs that we are interested in manipulating?
- Which host organism would make the best chassis?
- What should our GPCR be sensitive to?
Papers
- "Efficient production of membrane-integrated and detergent-soluble G protein-coupled receptors in Escherichia coli," article from Protein Science, 2008: http://www.ncbi.nlm.nih.gov/pubmed/18593817
- Article that discusses some of the complications that emerge when expressing GPCRs in microbial systems. One of the solutions this group found was co-expression of the GPCR-GFP construct with various regulatory proteins involved in membrane metabolism. Coexpression with the AAA+ protease FtsH, an enzyme involvedin MP degradation and quality control. (Article to be read in advance of Monday's meeting)

Questions
- I would highly recommend looking through George Georgiou's literature to see what engineered parts he has made. - Chris
- Thanks for the suggestion; the article for Monday's meeting is by Georgiou. Any other recommendations?
