What the structure of angiostatin may tell us about its mechanism of action

J Thromb Haemost. 2004 Jan;2(1):23-34. doi: 10.1111/j.1538-7836.2004.00544.x.


Originally discovered in 1994 by Folkman and coworkers, angiostatin was identified through its antitumor effects in mice and later shown to be a potent inhibitor of angiogenesis. An internal fragment of plasminogen, angiostatin consists of kringle domains that are known to be lysine-binding. The crystal structure of angiostatin was the first multikringle domain-containing structure to be published. This review will focus on what is known about the structure of angiostatin and its implications in function from the current literature.
