Recombinant Human TEK Tyrosine Kinase, Endothelial, His-tagged

Cat. No.: TEK-547H
Product Overview: Recombinant human TIE 2 was expressed bybaculovirus in Sf9 insect cellsusing an N-terminal GST tag. MW = 61 kDa.
Description: TIE 2 or TEK is a receptor tyrosine kinase that is expressed principally on vascular endothelium. Disrupting TIE 2 function in mice results in embryonic lethality with defects in embryonic vasculature, suggesting a role in blood vessel maturation and maintenance. Angiopoietin-1 is a secreted growth factor that binds to and activates the TIE 2 receptor tyrosine kinase. SHP2 and GRB2 are recruited to the activated TIE 2 kinase domain and are part of the cellular responses that mediate TIE 2 function. TIE 2 expression is upregulated in the endothelium of vascular "hot spots" in human breast cancer specimens. However, TIE 2 is also overexpressed in areas of active angiogenesis in normal tissues.
Source: Baculovirus infected Sf9 cells.
Purity: >60% by SDS-PAGE.
