Previous GeneCards Identifiers for NPPB Gene
This gene is a member of the natriuretic peptide family and encodes a secreted protein which functions as a cardiac hormone. The protein undergoes two cleavage events, one within the cell and a second after secretion into the blood. The protein's biological actions include natriuresis, diuresis, vasorelaxation, inhibition of renin and aldosterone secretion, and a key role in cardiovascular homeostasis. A high concentration of this protein in the bloodstream is indicative of heart failure. The presence of myocardial injury is a significant predictor of mortality in hospitalized coronavirus disease 2019 (COVID-19) patients, and there is evidence of increased levels of natriuretic peptide B in hospitalized non-survivor COVID-19 patients. The protein also acts as an antimicrobial peptide with antibacterial and antifungal activity. Mutations in this gene have been associated with postmenopausal osteoporosis.

GeneCards Summary for NPPB Gene
NPPB (Natriuretic Peptide B) is a Protein Coding gene. Diseases associated with NPPB include Constrictive Pericarditis and Systolic Heart Failure. Among its related pathways are cGMP-PKG signaling pathway and Respiratory electron transport, ATP synthesis by chemiosmotic coupling, and heat production by uncoupling proteins.. Gene Ontology (GO) annotations related to this gene include signaling receptor binding and diuretic hormone activity. An important paralog of this gene is NPPA.
UniProtKB/Swiss-Prot Summary for NPPB Gene
[Brain natriuretic peptide 32]: Cardiac hormone that plays a key role in mediating cardio-renal homeostasis (PubMed:9458824, PubMed:1672777, PubMed:1914098, PubMed:17372040). May also function as a paracrine antifibrotic factor in the heart (By similarity). Acts by specifically binding and stimulating NPR1 to produce cGMP, which in turn activates effector proteins that drive various biological responses (PubMed:9458824, PubMed:1672777, PubMed:17372040, PubMed:21098034, PubMed:17349887, PubMed:25339504). Involved in regulating the extracellular fluid volume and maintaining the fluid-electrolyte balance through natriuresis, diuresis, vasorelaxation, and inhibition of renin and aldosterone secretion (PubMed:9458824, PubMed:1914098). Binds the clearance receptor NPR3 (PubMed:16870210).
[NT-proBNP]: May affect cardio-renal homeostasis (PubMed:17372040). Able to promote the production of cGMP although its potency is very low compared to brain natriuretic peptide 32 (PubMed:17372040).
[BNP(3-32)]: May have a role in cardio-renal homeostasis (PubMed:17372040). Able to promote the production of cGMP (PubMed:17372040).
