Identification of methione aminopeptidase-2 (MetAP-2) as the molecular target of the antiangiogenic compound TNP-470 has sparked interest in N-terminal Met excision’s (NME) role in endothelial cell biology. In this regard, we recently demonstrated that MetAP-2 inhibition suppresses Wnt planar cell polarity (PCP) signaling and that endothelial cells depend on this pathway for normal function. Despite this advance, the substrate(s) whose activity is altered upon MetAP-2 inhibition, resulting in loss of Wnt PCP signaling, is not known. Here, we identify the small G-protein Rab37 as a novel MetAP-2 substrate that accumulates in the presence of TNP-470. A functional role for aberrant Rab37 accumulation in TNP-470’s mode-of-action is demonstrated using a Rab37 point-mutant that is resistant to NME because expression of this mutant phenocopies the effects of MetAP-2 inhibition on Wnt PCP signaling-dependent processes.
