|Product Overview:||Pyk2 Kinase (Human) Assay/Inhibitor Screening Assay Kit is a single-site, non-quantitative immunoassay for kinase activity of recombinant catalytic domain of Met. Plates are pre-coated with a newly designed "Tyrosine kinase-substrate-1", which can be easily phosphorylated by recombinant catalytic domain of Met. The detector antibody is PY-39, an antibody that specifically detects the phosphotyrosine residue on "Tyrosine kinase-substrate-1".|
|Description:||Intracellular signal transduction following extracellular ligation by a wide variety of surface molecules involves the activation and tyrosine phosphorylation of protein tyrosine kinases (PTKs). Tyrosine phosphorylation, controlled by the coordinated actions of protein tyrosine phosphatases and tyrosine kinases, is a critical regulatory mechanism for various physiological processes, including cell growth, differentiation, metabolism, cell cycle regulation and cytoskeleton function.The focal adhesion PTK family consists of the focal adhesion kinase (FAK) and the Pyk2 kinase (also known as RAFTK, CAK-beta and CADTK). Pyk2 kinase can be activated in response to various stimuli, such as TNF-alpha, changes in osmolarity, elevation in intracellular calcium concentration, lysophosphatidic acid, in addition of bradykinin, a neuropeptide hormone that binds to a G protein-coupled receptor and in turn stimulates phosphatidylinositol hydrolysis. Pyk2 kinase is expressed mainly in the central nervous system and in cells derived from hematopoietic lineages (1-3), while FAK is widely expressed in various tissues and links transmembrane integrin receptors to intracellular pathways.|
|Applications:||1) Screening inhibitors or activators of recombinant catalytic domain of Pyk2.2) Detecting the effects of pharmacological agents on recombinant catalytic domain of Pyk2.|
