Puromycin-insensitive leucyl-specific aminopeptidase (PILSAP) binds and catalyzes PDK1, allowing VEGF-stimulated activation of S6K for endothelial cell proliferation and angiogenesis.

Abstract excerpt

Puromycin-insensitive leucyl-specific aminopeptidase (PILSAP) plays an important role in angiogenesis by regulating the proliferation and migration of endothelial cells (ECs). Here we characterize the mechanism by which PILSAP regulates the vascular endothelial growth factor (VEGF)-stimulated proliferation of ECs. The specific elimination of PILSAP expression or its enzymatic activity inhibited VEGF-stimulated...
