SUBCELLULAR LOCALIZATION	extracellular
	plasma membrane
	intracellular

basic FUNCTION	involved in the systemic clearance of circulating natriuretic peptides and in the control of local effects of the natriuretic peptide system
	playing a role for in the regulation of glucagon secretion from human alpha cells (Burgess 2009)
	NPR3 protects cardiomyocytes from apoptosis through inhibition of cytosolic BRCA1 and TNF, which are regulators of apoptosis
	anti-apoptosis role of NPR3 in protecting cardiomyocytes suggesting molecular link between natriuretic peptides (NPs) system and programmed cell death
	NPR3 lacks the guanylate cyclase activity of NPR1 and NPR2 and is reportedly coupled to Gi-dependent signaling
	plays a pivotal role by differentially regulating two developmental programs through its dual function as clearance and signaling receptor
	regulates neural crest and cranial placode progenitors formation through its dual function as clearance and signaling receptor

INTERACTION

small molecule

protein	could interact with OSTN (modulating NPR3 actions on the skeleton) (Moffatt 2007)
	OSTN binds to NPR3 competitively with NPPA and may affect NPPA concentrations in a local or systemic manner
	role of NPR3 in anti-apoptosis via the breast cancer type 1 susceptibility protein (BRCA1) and TNF
	OSTN binds to natriuretic peptide receptor 3 (NPR3) in periosteal osteoprogenitors, thereby preventing NPR3-mediated clearance of NPPC and consequently facilitating NPPC-signal-mediated bone growth

ANIMAL & CELL MODELS

	its complete absence, unexpectidly produces skeletal abnormalities in mice
	continuous infusion of the peptide Ostn, an endogenous ligand of Npr3 secreted by bone and muscle cells, lowered blood pressure in wild-type mice, suggesting that endogenous natriuretic peptides play major roles in the regulation of blood pressure
