title: Observations on the renal processing and sorting of prorenin.
abstract: Human prorenin is the biosynthetic precursor of renin. In general, prorenin is enzymatically inactive until it is converted to renin. The kidney is the major source of renin in the circulation, and is also an important source of circulating prorenin. The mechanisms of prorenin sorting and processing to renin in the juxtaglomerular cell may be a determinant of renal renin production. Therefore, our studies have focused on renal enzymes involved in "limited proteolysis" of prorenin to renin and on the morphology of prorenin sorting in the human juxtaglomerular cell.
