The protein encoded by this gene belongs to the natriuretic peptide family. Natriuretic peptides are implicated in the control of extracellular fluid volume and electrolyte homeostasis. This protein is synthesized as a large precursor (containing a signal peptide), which is processed to release a peptide from the N-terminus with similarity to vasoactive peptide, cardiodilatin, and another peptide from the C-terminus with natriuretic-diuretic activity. Mutations in this gene have been associated with atrial fibrillation familial type 6. This gene is located adjacent to another member of the natriuretic family of peptides on chromosome 1.

GeneCards Summary for NPPA Gene
NPPA (Natriuretic Peptide A) is a Protein Coding gene. Diseases associated with NPPA include Atrial Standstill 2 and Atrial Fibrillation, Familial, 6. Among its related pathways are Oxytocin signaling pathway and MicroRNAs in cardiomyocyte hypertrophy. Gene Ontology (GO) annotations related to this gene include signaling receptor binding and neuropeptide hormone activity. An important paralog of this gene is NPPB.
UniProtKB/Swiss-Prot Summary for NPPA Gene
Hormone playing a key role in cardiovascular homeostasis through regulation of natriuresis, diuresis, and vasodilation. Also plays a role in female pregnancy by promoting trophoblast invasion and spiral artery remodeling in uterus. Specifically binds and stimulates the cGMP production of the NPR1 receptor. Binds the clearance receptor NPR3.
Natriuretic peptide (NP) receptors are single transmembrane catalytic receptors with intracellular guanylyl cyclase activity. There are three isoforms of NP receptors; NPR1-3, which have conserved catalytic and regulatory domains and divergent ligand binding domains.
