Recombinant Human TEK Tyrosine Kinase, Endothelial, His-tagged

Cat. No.: TEK-390H
Product Overview: Recombinant human TEK(a.a. 771-end) with N-terminal His tag, MW=45 kDa, expressed in an Baculovirusinfected Sf9 cell expression system.
Description: The TEK receptortyrosine kinase is expressed almost exclusively in endothelial cells in mice,rats, and humans. This receptor possesses a unique extracellular domaincontaining 2 immunoglobulin-like loops separated by 3 epidermal growth factor-likerepeats that are connected to 3 fibronectin type III-like repeats. The ligandfor the receptor is angiopoietin-1. Defects in TEK are associated withinherited venous malformations; the TEK signaling pathway appears to becritical for endothelial cell-smooth muscle cell communication in venousmorphogenesis. TEK is closely related to the TIE receptor tyrosine kinase.
