ACE-2, also known as angiotensin-converting enzyme 2, is an integral membrane protein and a zinc metalloprotease of the ACE family that also includes somatic and germinal ACE. It cleaves angiotensin 1 to angiotensin 1-9 and angiotensin 2 to angiotensin 1-7 as a carboxypeptidase. It may be an important regulator of heart function and have a protective role in acute lung injury. Also, it is a key SARS-CoV Spike protein receptor in vivo. Recombinant protein corresponding to aa18-740 from mouse ACE-2, fused to His-Tag at C-terminal, expressed in Baculovirus.
