摘要：

The rat pheochromocytoma cell line PC12 targets secretory proteins into two distinct pathways. When DNA encoding human prorenin was transfected into PC12 cells, the protein was sorted into the regulated secretory pathway and released with similar kinetics to noradrenaline upon carbachol stimulation. To determine whether information for targeting prorenin lies within the pro‐peptide we have transfected PC12 cells with a construct lacking the pro‐peptide coding sequence. The transformed line secretes an apparently fully active enzyme and responds to carbachol stimulation with a rapid release of renin activity. We conclude that the pro‐peptide of renin is not essential for targeting the protein to the regulated pathway in PC12 cells. Copyright © 1990, Wiley Blackwell. All rights reserved
