Angiopoietin-1 receptor also known as CD202B (cluster of differentiation 202B) is a protein that in humans is encoded by the TEK gene.[5][6] Also known as TIE2, it is an angiopoietin receptor.

Function

[edit]

The TEK receptor tyrosine kinase is expressed almost exclusively in endothelial cells in mice, rats, and humans. (TEK is closely related to the TIE receptor tyrosine kinase.)[7]

This receptor possesses a unique extracellular domain containing 2 immunoglobulin-like loops separated by 3 epidermal growth factor-like repeats that are connected to 3 fibronectin type III-like repeats.[8] The ligand for the receptor is angiopoietin-1.[7] TEK has also been suggested as a marker for nucleus pulposus progenitor cells, from the intervertebral disc, which upon activation by Angiopoietin-1 starts to multiply and differentiate.[9][10]

Defects in TEK are associated with inherited venous malformations; the TEK signaling pathway appears to be critical for endothelial cell-smooth muscle cell communication in venous morphogenesis.[7]

In cancer patients, TEK (Tie2) is expressed in a subpopulation of monocytes that home in on the tumor and are essential for the formation of new blood vessels there.[11]
