Adhesion plaques, specialized regions of the plasma membrane where a cell contacts its substratum, are dynamic structures. However, little is known about how the protein-protein interactions that occur at adhesion plaques are controlled. One mechanism by which a cell might modulate its associations with the substratum is by selective, regulated proteolysis of an adhesion plaque component. Here we show that the catalytic subunit of the calcium-dependent protease type II (CDP-II) is localized in adhesion plaques of several cell types (BS-C-1, EBTr, and MDBK). We have compared the susceptibility of the adhesion plaque constituents vinculin, talin, and alpha-actinin to calcium-dependent proteolysis in vitro and have found talin to be the preferred substrate for CDP-II. The colocalization of a calcium-requiring proteolytic enzyme and talin in adhesion plaques raises the possibility that calcium-dependent proteolytic activity provides a mechanism for regulating some aspect of adhesion plaque physiology and function via cleavage of talin.
