General description
纤溶酶原激活物抑制剂1 (PAI-1)或丝氨酸蛋白酶抑制剂E1 (SERPINE1)基因映射到人类染色体7q22.1。PAI-1在肝细胞、内皮细胞、平滑肌细胞、巨核细胞和脂肪细胞中产生。
Application
人纤溶酶原激活物抑制剂1 (PAI-1)已被用作:
- 放射免疫沉淀法(RIPA)中的脑源性神经营养因子(proBDNF)的抑制剂,用于外周血和淋巴细胞
- 阻断感染白色念珠菌菌丝
- 小鼠的纤溶酶活性,检测其对神经元神经突生长的影响
Biochem/physiol Actions
纤溶酶原激活物抑制剂1 (PAI -1)参与介导细胞衰老。它在损伤期间与其他组织修复转录组一起上调。PAI-1水平升高被认为是与心肌梗死(MI)相关的风险之一。
纤溶酶原激活物抑制剂1(PAI-1)是丝氨酸蛋白酶抑制剂Serpin超家族的一员,可参与到细胞外基质重塑并涉及血管生成、趋化性、排卵和胚胎生成等过程。
纤溶酶原激活物抑制剂1(PAI-1)蛋白属于丝氨酸蛋白酶抑制剂的Serpin超家族。它是组织纤溶酶原激活物(tPA)和尿激酶(uPA)的主要抑制剂,并也是纤溶酶原的激活剂,因此可抑制纤维蛋白溶解过程。 PAI可参与到细胞外基质的重塑,并涉及血管生成、趋化性、排卵和胚胎生成等过程。 PAI-1在各种疾病状态中的水平都有所上升,如多种癌症形式、肥胖症和代谢综合征。

Nuclear factor of activated T cells (NFAT) is activated in innate immune cells downstream of pattern recognition receptors, but little is known about NFAT's functions in innate immunity compared with adaptive immunity. We show that early activation of NFAT balances

Plasminogen activator, tissue type (PLAT) and its inhibitor serpin family E member 1 (SERPINE1) cooperatively regulate PLAT activity in various reproductive processes. However, it is unknown whether this includes bovine oocyte maturation. We addressed this question in the present study

A previous study had demonstrated that Leptospira enolase is secreted extracellularly by a yet unknown mechanism and reassociates with the bacterial membrane. Surface-anchored leptospiral enolase displays plasminogen binding activity. In this work, we explored the consequences of this interaction and
