The scope of phage display for membrane proteins.

ABSTRACT: Numerous examples of phage display applied to soluble proteins demonstrate the power of the technique for protein engineering, affinity reagent discovery and structure-function studies. Recent reports have expanded phage display to include membrane proteins (MPs). The scope and limitations of MP display remain undefined. Therefore, we report data from the phage display of representative types of membrane-associated proteins including plasma, nuclear, peripheral, single and multipass. The peripheral MP neuromodulin displays robustly with packaging by conventional M13-KO7 helper phage. The monotopic MP Nogo-66 can also display on the phage surface, if packaged by the modified M13-KO7(+) helper phage. The modified phage coat of KO7(+) can better mimic the zwitterionic character of the plasma
