Selectional and mutational scope of peptides sequestering the Jun-Fos coiled-coil domain.

Abstract excerpt

The activator protein-1 (AP-1) complex plays a crucial role in numerous pathways, and its ability to induce tumorigenesis is well documented. Thus, AP-1 represents an interesting therapeutic target. We selected peptides from phage display and compared their ability to disrupt the cFos/cJun interaction to a previously described in vivo protein-fragment complementation assay (PCA). A cJun-based library was screened...
