Isolation and identification of rat brain natriuretic peptides in cardiac atrium.

The amino acid sequence of a precursor for rat brain natriuretic peptide (BNP) has recently been deduced by the cDNA cloning method. By using a radioimmunoassay (RIA) system newly established for rat BNP, a high concentration of ir-BNP was found to exist in rat cardiac atrium. Two ir-BNPs of different molecular weights (11K and 5K) were isolated from rat cardiac atria by anti-rat BNP IgG immunoaffinity chromatography and reverse phase high performance liquid chromatography (HPLC). By microsequencing, the high molecular weight (MW) BNP was deduced to be a pro-BNP of 95 residues (gamma-BNP). The low MW BNP was demonstrated to be a C-terminal 45-amino acid peptide (BNP-45) of pro-BNP. Based on these results, BNP-45 and gamma-BNP are shown to be two major forms in rat cardiac atrium, indicating a unique processing pathway of rat BNP precursor.[1]
