Mouse Anti-BNP(H1G3) antibody
Brain natriuretic peptide (BNP) circulates in blood as a peptide hormone with natriuretic, vasodilatory and renin inhibitory properties. BNP is secreted predominantly by the left ventricular myocytes in response to volume expansion and pressure overload. BNP belongs to a family of structurally similar peptide hormones, which includes atrial natriuretic peptide (ANP), BNP, SLCtype natriuretic peptide (CNP) and urodilatin. These peptides are characterized by a common 17 amino acid ring structure with a disulfide bond between two cystein residues. This ring structure shows high homology between different natriuretic peptides (eleven of the 17 amino acid residues are homologous in the ring of each of the natriuretic peptides). BNP is a 32 amino acid peptide with disulfide bond between the cysteine residues Cys10 and Cys26. In earlier studies it has been demonstrated that BNP concentration in blood increases with the severity of congestive heart failure. Quantitative measurement of BNP in blood provides an objective indicator of congestive heart failure severity.
Function:
Cardiac hormone which may function as a paracrine antifibrotic factor in the heart. Also plays a key role in cardiovascular homeostasis through natriuresis, diuresis, vasorelaxation, and inhibition of renin and aldosterone secretion. Specifically binds and stimulates the cGMP production of the NPR1 receptor. Binds the clearance receptor NPR3.
Subcellular Location:
Secreted.
Tissue Specificity:
Brain and also in atria, but at much lower levels than ANP.
Similarity:
Belongs to the natriuretic peptide family.

脑钠素主要是心脏激素,心脏作为内分泌器官释放脑钠素,调解体液及电解质内环境的恒定性。
B型利钠肽(钠尿肽)(B-typenatriureticpeptide,BNP),又称脑钠素或脑钠肽,因其有排钠利尿、内皮非依赖性的血管平滑肌作用而具有降压、抗心肌纤维化、影响神经内分泌系统等功效。
近来发现BNP在各种心血管疾病,尤其是心室功能不全、急性心肌梗死(ami)、高血压等疾病的诊断、治疗及预后等方面有重要意义,已引起临床工作者的高度重视。
