酶&蛋白酶

Plasminogen activator inhibitor-1(PAI-1), a member of the serine protease inhibitor(serpin) super family. PAI-1 is the principal inhibitor of tissue plasminogen activator and urokinase, the activators of plasminogen and hence fibrinolysis. PAI-1 is mainly produced by the endothelium but is also secreted by other tissue types, such as adipose tissue. Recombinant human PAI-1, fused to His tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.

This gene encodes a member of the serine proteinase inhibitor (serpin) superfamily. This member is the principal inhibitor of tissue plasminogen activator (tPA) and urokinase (uPA), and hence is an inhibitor of fibrinolysis. Defects in this gene are the cause of plasminogen activator inhibitor-1 deficiency (PAI-1 deficiency), and high concentrations of the gene product are associated with thrombophilia. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009]

SERPINE1: a secreted protein that acts as bait for tissue plasminogen activator, urokinase, and protein C. Its rapid interaction with TPA may function as a major control point in the regulation of fibrinolysis. Belongs to the serpin family. Interacts with VTN. Binds LRP1B; binding is followed by internalization and degradation. Plasma levels of PAI-1 and VCAM-1 together may be useful in predicting post-operative recurrence in patients with colorectal cancer. Protein type: Secreted; Motility/polarity/chemotaxis; Secreted, signal peptide. Chromosomal Location of Human Ortholog: 7q22.1. Cellular Component: extracellular matrix; extracellular space; plasma membrane; extracellular region. Molecular Function: serine-type endopeptidase inhibitor activity; protein binding; protease binding; receptor binding. Biological Process: circadian rhythm; extracellular matrix organization and biogenesis; positive regulation of blood coagulation; negative regulation of smooth muscle cell migration; defense response to Gram-negative bacterium; positive regulation of receptor-mediated endocytosis; positive regulation of interleukin-8 production; negative regulation of fibrinolysis; platelet degranulation; transforming growth factor beta receptor signaling pathway; regulation of receptor activity; angiogenesis; chronological cell aging; negative regulation of cell adhesion mediated by integrin; negative regulation of cell migration; transcription initiation from RNA polymerase II promoter; platelet activation; transcription, DNA-dependent; negative regulation of blood coagulation; regulation of cell proliferation; fibrinolysis; positive regulation of angiogenesis; positive regulation of transcription from RNA polymerase II promoter; gene expression; blood coagulation; positive regulation of inflammatory response.
