Urokinase-Type Plasminogen Activator (PLAU) Antibody

PLAU antibody

PLAU(Urokinase-type plasminogen activator) is also named as uPA and belongs to the peptidase S1 family.UPA initiates a proteolytic cascade, which degrades extracellular matrix during tissue growth and remodelling.The secreted proform of UPA is activated after binding to a specific high affinity cell surface receptor. Secreted UPA is exposed to rapid inactivation in the pericellular space by plasminogen activator inhibitor-1(PAI-1), which is stored in the extracellular matrix bound to vitronectin(PMID:9665342).It has 2 isoforms produced by alternative splicing.Defects in PLAU are the cause of Quebec platelet disorder(QPD).

Urokinase-Type Plasminogen Activator (PLAU) Antibody

PLAU Antibody is a Rabbit Polyclonal antibody against PLAU. 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.
