It is a receptor that binds to angiopoietin of angiopoietin receptor. Bind the TIE-1, TIE-2, and contains a cell surface receptor that is activated angiopoietin (to Ang1, Ang2 is, Ang3, Ang4) by. Angiopoietin is a protein growth factors required for the formation of blood vessels (angiogenesis). Angiopoietin is a factor that promotes the formation of a growth protein angiogenic blood vessels. The Ang1, Ang2 is, Ang3, Ang4: will be identified angiopoietin-4 are present. Ang4 function as an activating ligand or agonist Ang1 -2 dove tie, Ang2 pigeon Ang3 While acting as a competitive antagonist. They act by binding physiological receptor, Thailand 1, Thailand 2. To initiate the intracellular signaling thereby so mediate cellular signals by inducing tyrosine phosphorylation key, the receptor tyrosine kinases are, they are named as such. There is room for discussion which bits of Thailand receptor that mediates the downstream function signal of Ang stimulation of it. However, it is Thailand, it may result in the physiological activation of the angiopoietin-2 binding is clear at least.

TEK tyrosine kinase receptor is expressed almost exclusively in endothelial cells of mouse, rat and human. This receptor has an extracellular domain unique comprising lines 3 immunoglobulin-like two-separated epidermal growth factors such as repetition associated with the fibronectin type III-like repeats three. Ligand of the receptor is angiopoietin-1. I appears to be important for endothelial cell communication is associated with venous malformation defects TEK is inherited, in vein morphogenesis of TEK signaling pathway, of smooth muscle cells. TEK is closely related to receptor tyrosine kinases gender.

For example, the endothelial cell surface, plays an important role in physiological and pathological processes several important such as angiogenic effect blood coagulation and inflammation. We write equality, cloning and properties of a new type of human endothelial cell surface receptor tyrosine kinase here. Exclusive pair consisting of groups of three motivational epidermal growth factor embedded between two lines fibronectin type III adjacent to the transmembrane region repeated three times homology immunoglobulinlike the extracellular domain of the protein product to be predicted more were I have a multi-domain structure. Furthermore, the DNA form lacking the first two regions homologous to epidermal growth factor, suggesting that creating a gender type different receptors, alternative splicing was isolated. I to produce a glycosylated polypeptide of 118 kDa which reacts with antisera cells infected in Thailand DNA expression vector was raised against the carboxy terminus somehow. Thailand gene is located on chromosome 1p33 region 1p34 on. It looks and expression of Thai so that the gene is limited by a particular cell line, red blood cells megakaryoblastoid characteristics and some myeloid leukemia cell line and endothelial cell line of a large amount of Thailand mRNA was found. In addition, the position of the mRNA study also indicates the gene expression of endothelial cells of equality. Protein can include adhesion to vascular endothelial cells linked receptor tyrosine kinase, – protein interactions, may be various developed.

Have been identified as ligands in the effector functions of different maturation mediator receptor tyrosine kinases Tie 2 and angiopoietin 2 (angiotensin -1) and (-2 en) vessel assembly angiopoietin 1. To understand the molecular interaction of angiopoietin to its receptor, we examined the binding of Ang-2 and Ang-1 and 2 receptor Thailand. Competition assays, and based on the analysis of the immunoprecipitation experiments cooperative binding of Ang-2 mutants of the extracellular domain of the Ig-like loop tie Figure A-2 of the first two pairs in combination with the epidermal growth factor-en -1 This is necessary for enzyme-linked immunosorbent assay (EGF), as to repeat (amino acids 1-360) angiopoietin-binding. EGF-like repeats and Ig-like domain of the first will not be able to bind Ang-2 and Henri -1 alone. At the same time, we made a startling discovery Thailand exon 2 -2 knockout mice that expressing -2 protein-deficient mutant Thailand 104 amino acids of the Ig-like domain of the first. As evidenced by the absence of phosphorylation of the receptor and ligand binding, receptor 2 This mutation tie is functionally active. Collectively, it is indicated that not enough data is essential for binding of the 104 amino acids angiopoietins first 2 receptor Thailand. On the other hand, (and Ig-like domain, EGF-like repeats) 360 amino acids of the first 2 receptor Thailand, shows that differential receptor binding is not possible, and Ang-1 both as necessary responsible for different functions of Ang-2 and Ang-1 of which is sufficient to bind to the Ang-2.

Express SVR EC is, Dokdo R levels and relatively high Tech. In order to assess whether may be a phosphorylated tyrosine in response to stimulation of Ang1 in EC Dokdo R is the associate Tech, we stimulated SVRS with conditioned medium containing the Ang1 . The Briefly, the conditioned medium following Ang1 is-MH were harvested from the parent cell line which is not transfected conditioned media harvested from HEK 293T cells expressing the shape of the fusion Ang1, the His epitope tag and Myc Stable It is used as a control stimulus that many models, was used as a stimulant as. The treatment of the EC and the SVR, Ang1-MH to stimulate the tyrosine phosphorylation of co-immunoprecipitation and Tech Dokdo R is the first document that occurred this interaction because EC. In addition, Ang1-MH will lead to co-immunoprecipitation of NCK and tyrosine phosphorylation and stimulation SVRS Dokdo R phosphorylation. The increased amount of phosphorus NCK, the majority of the immune discovery Dokdo-related NCK R indicates that it is tyrosine phosphorylated Dokdo R NCK is compared immunity.
