PLAU基因编码尿激酶型纤溶酶原激活剂(uPA),这是一种丝氨酸蛋白酶,在纤溶系统中发挥关键作用。uPA的主要功能是将纤溶酶原转化为纤溶酶,从而降解纤维蛋白和其他细胞外基质成分,参与组织重塑、伤口愈合、炎症反应和肿瘤转移等过程。uPA通过与细胞表面的uPAR受体结合发挥作用,其活性位点位于蛋白酶结构域。PLAU基因突变可能导致纤溶系统功能异常,与血栓形成、出血性疾病或肿瘤侵袭性增加相关。研究表明,PLAU过表达与多种癌症的进展和转移密切相关,如乳腺癌、结肠癌和肺癌,因其促进肿瘤细胞侵袭和血管生成;而PLAU表达降低可能减少肿瘤转移风险,但可能影响正常组织修复。PLAU属于纤溶酶原激活剂基因家族,该家族还包括组织型纤溶酶原激活剂(PLAT),两者均通过激活纤溶酶原参与纤溶过程,但uPA更侧重于细胞迁移和组织重塑,而tPA主要参与血管内血栓溶解。PLAU还参与细胞信号传导,影响细胞增殖、黏附和迁移。此外,PLAU与阿尔茨海默病等神经退行性疾病有关,因其可能影响β-淀粉样蛋白的清除。在炎症中,PLAU通过调节免疫细胞迁移参与炎症反应。该基因的表达受多种因素调控,包括生长因子、细胞因子和激素等。

This gene encodes a serine protease involved in degradation of the extracellular matrix and possibly tumor cell migration and proliferation. A specific polymorphism in this gene may be associated with late-onset Alzheimer's disease and also with decreased affinity for fibrin-binding. This protein converts plasminogen to plasmin by specific cleavage of an Arg-Val bond in plasminogen. Plasmin in turn cleaves this protein at a Lys-Ile bond to form a two-chain derivative in which a single disulfide bond connects the amino-terminal A-chain to the catalytically active, carboxy-terminal B-chain. This two-chain derivative is also called HMW-uPA (high molecular weight uPA). HMW-uPA can be further processed into LMW-uPA (low molecular weight uPA) by cleavage of chain A into a short chain A (A1) and an amino-terminal fragment. LMW-uPA is proteolytically active but does not bind to the uPA receptor. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

该基因编码参与细胞外基质的降解,并可能肿瘤细胞迁移和增殖的丝氨酸蛋白酶。在该基因的具体多态性可能与迟发型阿尔茨海默氏病相关联,并且还具有降低的亲和力的纤维蛋白结合。这种蛋白由纤维蛋白溶酶原的精氨酸 - 瓦尔债券的具体裂解转化纤溶酶原为纤溶酶。纤溶酶反过来切割该蛋白在一个赖氨酸 - 异亮氨酸键,以形成在其中单个二硫键的氨基末端A链连接到催化活性,羧基端B链的两链衍生物。该双链衍生物也称为HMW-uPA的(高分子量的uPA)。 HMW-uPA的可以由链A的切割进一步加工成LMW-uPA的(低分子量的uPA)成短链中的(A1)和氨基末端片段。 LMW-uPA的是蛋白水解活性的,但不绑定到特异受体。已发现该基因编码不同亚型选择性剪接转录变异体。 [由RefSeq的,2009年2月提供]
