In vitro, the metalloprotease MetAP-2 catalyzes the hydrolysis of N-terminal methionine residues. MetAP-2 is highly conserved across species. The catalytic domains of S. cerevisiae and human MetAP-2 proteins are ~80% homologous. The function of MetAP-2 in vivo remains to be determined. MetAP-2 has been identified, purified and cloned from rat cells as a 67kD eIF-2-associated (elongation inhibitory factor-2) protein, suggesting a possible role in protein translation. Provocative experiments suggest MetAP-2 may also be involved in angiogenesis, the process of new blood vessel formation. In these studies, MetAP-2 was determined to be the major cellular protein covalently bound to the potent anti-angiogenic agent fumagillin, following fumagillin treatment of HUVEC (human umbilical endothelial cells) cells or calf brain homogenates. Fumagillin was able to selectively inhibit the growth of a MetAP-2-dependent yeast strain. The fungal derived fumagillin, and its more potent metabolite TNP-470 (now in clinical trials), are effective at limiting both the size and metastasis of solid tumors. TNP-470 inhibits neovascularization via endothelial cell cycle arrest in the late G1 phase. The details of this process are not well understood. In view of the identification of MetAP-2 as a fumagillin binding protein, future studies with MetAP-2 should provide important new insights into the mechanisms of fumagillin/TNP- 470 induced cell-cycle arrest and the role of MetAP-2 in angiogenesis.
