Tyrosine kinase with immunoglobulin-like and EGF-like domains 1 also known as TIE1 is an angiopoietin receptor which in humans is encoded by the TIE1 gene. [1 ]
Function [ edit ]
TIE1 is a cell surface protein expressed exclusively in
endothelial cells, however it has also been shown to be expressed in immature hematopoietic cells and platelets. [2 ] TIE1 upregulates the [3 ] cell adhesion molecules (CAMs) VCAM-1, E-selectin, and ICAM-1 through a p38-dependent mechanism. Attachment of monocyte derived immune cells to endothelial cells is also enhanced by TIE1 expression. TIE1 has a proinflammatory effect and may play a role in the endothelial inflammatory diseases such as atherosclerosis. [4 ]
