p120-catenin mainly regulates

Cadherin stability at membrane, is consistent with established principles of cell signaling, receptor pharmacology and cellular regulation. Experimental measurements of binding parameters, genetic loss-of-function studies and pharmacological interventions all converge on the same interpretation. Related options address neighboring concepts but do not satisfy the precise criterion stated in the question.

Cell Communication and Cell Adhesion

Key adaptor proteins in adherens junctions are

Adaptor proteins contain modular interaction domains but lack intrinsic catalytic activity; they function solely to bring other proteins into proximity. Scaffold proteins organize multiple components of a pathway into a discrete complex, thereby enhancing specificity, speed and spatial restriction of signaling. Both classes of proteins are essential for the fidelity of intracellular information transfer.
