Angiopoietin-1 receptor also known as CD202B (cluster of differentiation 202B) is a protein that in humans is encoded by the TEK gene. Also known as TIE2, it is an angiopoietin receptor.
Contents
Function
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.)
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. The ligand for the receptor is angiopoietin-1.
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.
