WebDesmosomes are intracellular adhesion structures that are critical for cell–cell attachment in the epithelial and myocardial tissues and in other tissues (16). The desmosomal cadherin family is a major structural unit of the desmosome. It is composed of desmogleins (DSGs) and desmocollins (DSCs). WebA. Each member of the family recognizes only a single ECM protein. B. All integrins are involved in the cell-ECM adhesion. C. Integrin binding of ECM can stimulate cell-signaling pathways that regulate cell growth, survival and gene expression. D. Integrins are a major component of the zonula adherens junctions.
