Proteinase-Activated Receptors: New Functions for Old Enzymes
Abstract
Although proteases are traditionally viewed as degradative enzymes, characterization of a family of G protein-coupled receptors that are activated by proteolysis reveals a new role. Certain proteases function as signaling molecules that specifically regulate cells by cleaving and activating a family of proteinase-activated receptors.
