| Research Abstract |
Adipocyte-derived leucine aminopeptidase, leukocyte-derived arginine aminopeptidase and Laeverin are belonging to the M1 family of zinc-metallo aminopeptidases. In this study, biochemical and cell biological analyses were conducted to comprehend their catalytic mechanisms and characteristic subcellular localization/tissue distribution (endoplasmic reticulum retention or placenta specific expression). Several amino acid residues essential for catalysis were identified and genetic/cell biological tools (reporter plasmids and cell lines) were also established.
