FUNCTION: This gene encodes a secreted protein that belongs to the family of natriuretic peptides. Its precursor protein is processed to generate the active mature peptide. The mature peptide is a cardiac hormone that plays a role in ventricular remodeling as well as blood pressure regulation. Mice lacking this gene exhibit cardiac fibrosis. In humans this gene is associated with congestive heart failure, low bone-mineral density and postmenopausal osteoporosis. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Dec 2013]
PHENOTYPE: Homozygotes for a targeted null mutation develop multifocal fibrotic ventricular lesions which become larger and more numerous under conditions of ventricular pressure overload. [provided by MGI curators]
