Background: ACE-2

Angiotensin I Converting Enzyme 2 (ACE2), also known as ACEH (ACE homologue), is an integral membrane protein and a zinc metalloprotease of the ACE family (theoretical molecular weight 92 kDa). The predicted mouse ACE2 protein sequence consists of 798 amino acids, including an N-terminal signal peptide, a single catalytic domain, a C-terminal membrane anchor, and a short cytoplasmic tail. Mouse ACE2 is 40% homologous in amino acid identity to the N- and C-terminal domains of mouse somatic ACE. Enzymatically, ACE2 converts the inactive vasoconstrictor angiotensin I (AngI) to Ang1-9 and the active form AngII to Ang1-7, unlike ACE, which converts Ang I to Ang II.

Genetic data from Drosophila, mice and rats show that the ACE2 protein is an essential regulator of heart function in vivo. ACE2 mRNA is found at high levels in testis, kidney and heart with moderate levels in colon, small intestine, and ovary. The ACE2 protein contributes to organ function through the renin-angiotensin system, playing a central role in vascular, renal, and myocardial physiology.

Virology research has demonstrated that the severe acute respiratory syndrome coronavirus (SARS-CoV) spike protein binds to its functional receptor, ACE2 (1). Vimentin is a type III intermediate filament protein expressed in mesenchymal cells that helps comprise the cytoskeleton in all animal cells. Studies have demonstrated that vimentin allows cell binding that allows the uptake of SARS-CoV spike protein into a host (2). This direct interaction of SARS-CoV with vimentin has been identified as an entry mechanism for the virus into a host, mediated by the SARS-CoV receptor ACE2 (1,2). It has been shown that ACE2 is the SARS-CoV-2 receptor required for cell entry and plays a physiological role in the replication of SARS-CoV in an infected host (1). Studies using human ACE2 antibody demonstrated a blockade of SARS-CoV-2 and ACE2 interaction, indicating an important physiological component of viral transmission and potential anti-viral therapeutic strategies (3).

FAQs for Human ACE-2 ELISA Kit (Chemiluminescence)

Showing  1 - 2 of 2 FAQs Showing All

  • Q: Hello; I was wondering if NOVUS had any information or reference regarding "normal" ACE2 levels? I purchased NBP2-66387

    A: Unfortunately, we do not have any info or references on the levels of ACE2 that is defined as normal. We would recommend performing a literature search for this info for the type of samples you would be using.

  • Q: I'm interested in the ELISA kit (NBP2-66387). But I'm not sure what's the immunogen (standard) included in the kit. because we are going to use this kit to detect variant of human ACE2.

    A: The immunogen for the capture antibody was AA195-275 and the immunogen for the detection antibody was AA430-545. If your variant contains those amino acids, then this kit should work for you.
