Hemidesmosome Formation Is Initiated by the β4 Integrin Subunit, Requires Complex Formation of β4 and HD1/Plectin, and Involves a Direct Interaction between β4 and the Bullous Pemphigoid Antigen 180

Abstract excerpt

Hemidesmosomes (HDs) are stable anchoring structures that mediate the link between the intermediate filament cytoskeleton and the cell substratum. We investigated the contribution of various segments of the beta4 integrin cytoplasmic domain in the formation of HDs in transient transfection studies using immortalized keratinocytes derived from an epidermolysis bullosa patient deficient in beta4 expression. We...
