Specificity
This antibody recognises human Angiotensin-converting enzyme 2, also known as ACE2, ACE-related carboxypeptidase or Metalloprotease MPROT15. ACE2 is a 788 amino acid ~100 kDa carboxypeptidase expressed in a range of tissues including heart, kidney, testis and the gastrointestinal system. ACE2 is a homologue of ACE (Angiotensin-converting enzyme 1), although it has a distinct catalytic activity. ACE2 catalyzes the cleavage of active angiotensin II into angiotensin 1-7, which may counteract the effects of ACE by increasing vasodilatation.ACE2 serves as the cellular entry point for the severe acute respiratory syndrome (SARS) virus, functioning as a receptor for the SARS Spike protein.
