Isolation and nucleotide sequence of a cloned cardionatrin cDNA

A cloned cDNA which codes for the C-terminal 62 residues of the precursor molecule for the atrial natriuretic factor, cardionatrin, has been isolated and sequenced. The nucleotide sequence confirms the amino acid sequence of cardionatrin 1-28 previously determined, and positions this peptide at the C-terminal end of the precursor just two residues away from the termination codon.
