General description
Recombinant, human ACE-2 ectodomain (amino acids 1-740) fused at the C-terminus to a His•Tag sequence and expressed in NSO cells. ACE-2 cleaves angiotensins I and II as a carboxypeptidase and plays an important role in regulating cardiovascular and renal functions. Native ACE-2 is an integral membrane zinc metalloprotease whose activity is inhibited by EDTA. By SDS-PAGE, the apparent molecular mass of the glycosylated protein is ~120 kDa under either reducing or non-reducing conditions.
