Corin是一种在心脏中发现的跨膜丝氨酸蛋白酶,它将利钠肽从无活性的前体转化为成熟的活性形式。对动物模型和高血压和心脏病患者的研究表明,科林对维持正常血压和心脏功能至关重要。像许多蛋白水解酶一样,corin的表达和活性受到调控。细胞生物学实验表明,转录控制、细胞内蛋白运输、细胞表面靶向、酶原激活和外畴脱落是调节心脏中corin表达和活性的重要机制。最近,在人类血液中检测到可溶性科林,发现其水平在心力衰竭(HF)患者中降低。这些发现表明,可溶蛋白缺乏可能参与HF的发病机制,并提示可溶蛋白可作为该疾病的生物标志物。在这篇综述中,我们描述了科林的功能和调控,并讨论了人类血液中可溶性科林的最新研究及其作为心衰生物标志物的潜在用途。
Corin is a transmembrane serine protease identified in the heart, where it converts natriuretic peptides from inactive precursors to mature active forms. Studies in animal models and patients with hypertension and heart disease demonstrate that corin is critical in maintaining normal blood pressure and cardiac function. Like many proteolytic enzymes, corin expression and activity are regulated. Cell biology experiments indicate that transcriptional control, intracellular protein trafficking, cell surface targeting, zymogen activation and ectodomain shedding are important mechanisms in regulating corin expression and activity in the heart. More recently, soluble corin was detected in human blood and its levels were found to be reduced in patients with heart failure (HF). These findings indicate that corin deficiency may be involved in the pathogenesis of HF and suggest that soluble corin may be used as a biomarker for the disease. In this review, we describe the function and regulation of corin and discuss recent studies of soluble corin in human blood and its potential use as a biomarker for HF.
