Atrial Natriuretic

Rat brain natriuretic peptide (rBNP) and iso-atrial natriuretic peptide (iso-rANP) were discovered independently by two research laboratories. They are considered to be members of the B-type natriuretic peptides. Except for the Gln/Leu substitution at position 44, the amino acid sequence of iso-rANP is identical with that of the C-terminal 45 amino acids of rat pro-BNP and with the 5-kDa cardiac peptide from rat atria. To determine whether this amino acid substitution can modify the known biological effects of rBNP and iso-rANP, the present investigation examined the cardiovascular and renal responses, vasorelaxant effect, receptor binding characteristics, and cyclic GMP production by the two peptides in relation to that of rat atrial natriuretic peptide (rANP). Results indicate that rBNP and iso-rANP are indistinguishable from each other in terms of these known biological activities of atrial natriuretic peptide. We therefore conclude that rBNP and iso-rANP are identical peptides and that the amino acid substitution at position 44 represents a polymorphic form of the rat B-type natriuretic peptide.Key words: atrial natriuretic peptide, brain natriuretic peptide, cardiovascular response, vasorelaxation, cyclic GMP, receptor binding.
