The integrin beta4 has a long cytodomain necessary for hemidesmosome formation. A yeast two-hybrid screen using beta4 cytodomain uncovered a protein called p27(BBP) that represents a beta4 interactor. Both in yeast and in vitro, p27(BBP) binds the two NH2-terminal fibronectin type III modules of beta4, a region required for signaling and hemidesmosome formation. Sequence analysis of p27(BBP) revealed that p27(BBP) ... [more]
