CC   -!- FUNCTION: Hormone playing a key role in cardiovascular homeostasis
CC       through regulation of natriuresis, diuresis, and vasodilation. Has a
CC       cGMP-stimulating activity (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- TISSUE SPECIFICITY: Expressed in heart atrium and to a lower extent in
CC       heart ventricle, but not in brain. {ECO:0000269|PubMed:15072558}.
CC   -!- PTM: Cleaved upon secretion to produce the functional hormone.
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the natriuretic peptide family. {ECO:0000305}.
