TIMP-2 (Tissue inhibitor of metalloproteinase 2) is a nonglycosylated protein that belongs to the protease inhibitor I35 (TIMP) family. Contains 1 NTR domain, predicted molecular weight 24 kD. The mechanisms of TIMPs inhibit angiogenesis appear to be specific for each member of the TIMP family. TIMP-2 binds to the surface of human endothelial cells through interaction with the integrin alpha3beta1, and abrogates angiogenic factor induced endothelial cell proliferation in vitro and angiogenesis in vivo independent of MMP inhibition. Clone F27P3A4 has been shown to be useful for western blotting, immunohistochemistry and ELISA of human, mouse, rabbit, chicken, zebrafish, and pig TIMP-2.
