Angiostatin which contains the first four kringle domains of plasminogen has been documented to be a potent inhibitor of angiogenesis. More recently, another kringle structure within plasminogen but outside angiostatin, known as kringle 5 (K5), was found to inhibit endothelial cell proliferation and migration. Here, we report the cloning and expression of mouse kringle 5 (rK5) in a bacterial expression system. The protein was purified to homogeneity using a Ni-NTA column. rK5 inhibited both… CONTINUE READING
