Anti-TIE2 antibody [EPR26540-78] is a Rabbit Monoclonal antibody that is used in TIE2 Western Blot. Suitable for Human, Mouse samples.

The TIE2 receptor, a tyrosine kinase, is activated by angiopoietins like Ang1 and Ang2, regulating blood vessel formation and stability. Ang1 promotes vessel maturation and stabilization, while Ang2, often upregulated in tumors, can destabilize vessels and promote angiogenesis. The TIE2 pathway influences tumor microenvironment by affecting vascular integrity and immune cell infiltration, impacting tumor growth and metastasis. Tie2-expressing monocytes (TEMs), a subtype of tumor-associated macrophages (TAMs), exhibit a pro-angiogenic function in tumor tissue and are proposed as biomarkers and therapeutic targets for glioma, arthritis, and thrombus recanalization. TIE2 is also a target for anti-angiogenic treatments, and its inhibition may improve outcomes by reducing tumor vascularity and enhancing immune responses.

The antibody ab221154 exhibits low sensitivity in Western blot analyses. To improve detection of full-length TIE2, we recommend substituting with ab307556 or ab259982. Alternatively, experimental conditions can be optimized through increasing sample loading quantity, using lower antibody dilution or implementing femtogram-level sensitivity detection substrates.

Important note : TIE2 undergoes proteolytic cleavage (PMID : 32838837, PMID : 26666854). These three antibodies target distinct cleaved fragments of TIE2 due to differences in their immunogen localization.

Supplementary information

TIE2 also known as TEK or CD202B is a receptor tyrosine kinase with a mass of approximately 145 kDa. It plays an important role in vascular development and maintenance. TIE2 is mainly expressed in endothelial cells which line the interior surface of blood vessels. It binds angiopoietins predominantly Angiopoietin-1 (Angpt1) influencing vascular stability and permeability. Researchers use TIE2 antibodies including anti-TIE and anti-clone to study its role and functions across various contexts.
Biological function summary

TIE2 plays a central role in angiogenesis and blood vessel maturation. It forms a receptor complex with other components to mediate its effects. This interaction mainly involves Angpt1 which binds to TIE2 stabilizing blood vessels and preserving their integrity. TIE2 also participates in cell survival and migration processes necessary for normal vascular function. Researchers often perform Angpt1 ELISA in bulk to quantify interactions involving TIE2 in experiments.

Pathways

TIE2 is important in the angiopoietin-TIE signaling pathway regulating vascular development. TIE2 is related to proteins such as Angpt1 which are centrally involved in this pathway. It also interacts with various signaling molecules including phosphatidylinositol-3-kinase (PI3K) which contributes to cell survival pathways. Alterations in the TIE2 signaling cascade can lead to aberrant angiogenesis and related pathologies.

TIE2 is implicated in several vascular diseases and cancer. Mutations or dysregulation of TIE2 can result in venous malformations and further compromise blood vessel integrity. In cancer TIE2 expression can influence tumor angiogenesis enhancing tumor growth and metastasis. TIE2 interacts with proteins like vascular endothelial growth factor (VEGF) which are involved in neovascularization and cancer progression. Understanding these interactions helps target therapeutic strategies in relevant diseases.

Target data

Tyrosine-protein kinase that acts as a cell-surface receptor for ANGPT1, ANGPT2 and ANGPT4 and regulates angiogenesis, endothelial cell survival, proliferation, migration, adhesion and cell spreading, reorganization of the actin cytoskeleton, but also maintenance of vascular quiescence. Has anti-inflammatory effects by preventing the leakage of pro-inflammatory plasma proteins and leukocytes from blood vessels. Required for normal angiogenesis and heart development during embryogenesis. Required for post-natal hematopoiesis. After birth, activates or inhibits angiogenesis, depending on the context. Inhibits angiogenesis and promotes vascular stability in quiescent vessels, where endothelial cells have tight contacts. In quiescent vessels, ANGPT1 oligomers recruit TEK to cell-cell contacts, forming complexes with TEK molecules from adjoining cells, and this leads to preferential activation of phosphatidylinositol 3-kinase and the AKT1 signaling cascades. In migrating endothelial cells that lack cell-cell adhesions, ANGT1 recruits TEK to contacts with the extracellular matrix, leading to the formation of focal adhesion complexes, activation of PTK2/FAK and of the downstream kinases MAPK1/ERK2 and MAPK3/ERK1, and ultimately to the stimulation of sprouting angiogenesis. ANGPT1 signaling triggers receptor dimerization and autophosphorylation at specific tyrosine residues that then serve as binding sites for scaffold proteins and effectors. Signaling is modulated by ANGPT2 that has lower affinity for TEK, can promote TEK autophosphorylation in the absence of ANGPT1, but inhibits ANGPT1-mediated signaling by competing for the same binding site. Signaling is also modulated by formation of heterodimers with TIE1, and by proteolytic processing that gives rise to a soluble TEK extracellular domain. The soluble extracellular domain modulates signaling by functioning as decoy receptor for angiopoietins. TEK phosphorylates DOK2, GRB7, GRB14, PIK3R1; SHC1 and TIE1.
