Intracellular retention of the extracellular domain of the (pro)renin receptor in mammalian cells.

ABSTRACT

As a component of the renin-angiotensin system, the (pro)renin receptor [(P)RR] activates prorenin along with intracellular signaling pathways. In this study, the glutathione S-transferase-fused extracellular domain of (P)RR expressed in mammalian cells was recovered in the detergent phase in detergent-based two-phase separation experiments, and intracellular localization was observed by immunocytochemistry, suggesting retention inside the cell through stable membrane association.
