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 inter-
action to a previously described in vivo protein-fragment complementa-
tion assay (PCA). A cJun-based library was screened to enrich for peptides
