In cultured cardiomyocytes, a point mutation was introduced into β1\beta_1-integrin that preserves surface expression but reduces binding to fibronectin in the extracellular matrix. Under cyclic stretch, mutant cells showed increased detachment and disrupted alignment of actin stress fibers, despite normal actin and myosin levels. Based on the scenario, which outcome is most consistent with the protein's function?
