In primate placenta, extravillous trophoblast (EVT) invades maternal tissue in temporally- and spatially-regulated fashions. We previously identified a novel placenta-specific cell-surface aminopeptidase, laeverin/aminopeptidase Q, which is expressed on EVT-lineage cells in the fetal membrane. Laeverin possesses a peptide-binding site that is evolutionally unique to primates, suggesting possible involvement of laeverin in a primate-specific phenomenon during placentation. Thus, this study was designed to elucidate the molecular characteristics and physiological roles of laeverin in human EVT.
