Y392_METJA A site-2 regulated intramembrane protease (S2P), its endogenous substrate is unknown. Regulated intramembrane proteolysis (RIP) occurs when an extracytoplasmic signal triggers a concerted proteolytic cascade to transmit information and elicit cellular responses. A membrane-spanning regulatory substrate protein is first cut extracytoplasmically (site-1 protease, S1P), then within the membrane itself (site-2 protease, S2P, this enzyme), while cytoplasmic proteases finish degrading the regulatory protein, liberating the effector protein. Possible signals, S1P and substrates are unknown in this organism.
