Supplementary information

The ACE2 protein also known as angiotensin-converting enzyme 2 is an essential component in the renin-angiotensin system. It functions mechanically by converting the hormone angiotensin II to angiotensin-(1-7) which helps regulate blood pressure and fluid balance. The molecular weight of ACE2 is approximately 120 kDa. This protein is expressed in various tissues particularly the lungs heart kidneys and gastrointestinal tract. In cultured cells like Caco-2 cells researchers often study this expression.
Biological function summary

The ACE2 protein plays an important role in the regulation of cardiovascular and renal functions. It is a single-pass type I membrane protein and its activity reduces inflammation and oxidative stress in cells. ACE2 does not function as part of a larger protein complex but its enzymatic conversion has a substantial impact on reducing the effects of angiotensin II in the body leading to vasodilation and decreased blood pressure.

Pathways

ACE2 involvement is significant in the renin-angiotensin system and the kallikrein-kinin system. These pathways are essential for maintaining cardiovascular homeostasis. In the renin-angiotensin system ACE2 works in opposition to angiotensin-converting enzyme (ACE) balancing the effects through the production of angiotensin-(1-7) from angiotensin II. Additionally ACE2 interacts indirectly with proteins like angiotensin receptor type 1 (AT1) and angiotensin receptor type 2 (AT2) ensuring proper signaling and physiological responses.

ACE2 links closely with conditions such as hypertension and COVID-19. Increased activity of angiotensin II due to low ACE2 levels contributes to hypertension. In infectious disease SARS-CoV-2 virus responsible for COVID-19 uses ACE2 as an entry receptor to initiate infection in host cells. This interaction highlights the importance of ACE2 in disease pathogenesis and has prompted interest in ACE2 as a potential therapeutic target.

Target data

Essential counter-regulatory carboxypeptidase of the renin-angiotensin hormone system that is a critical regulator of blood volume, systemic vascular resistance, and thus cardiovascular homeostasis (PubMed : 27217402). Converts angiotensin I to angiotensin 1-9, a nine-amino acid peptide with anti-hypertrophic effects in cardiomyocytes, and angiotensin II to angiotensin 1-7, which then acts as a beneficial vasodilator and anti-proliferation agent, counterbalancing the actions of the vasoconstrictor angiotensin II (PubMed : 10924499, PubMed : 10969042, PubMed : 11815627, PubMed : 14504186, PubMed : 19021774). Also removes the C-terminal residue from three other vasoactive peptides, neurotensin, kinetensin, and des-Arg bradykinin, but is not active on bradykinin (PubMed : 10969042, PubMed : 11815627). Also cleaves other biological peptides, such as apelins (apelin-13, [Pyr1]apelin-13, apelin-17, apelin-36), casomorphins (beta-casomorphin-7, neocasomorphin) and dynorphin A with high efficiency (PubMed : 11815627, PubMed : 27217402, PubMed : 28293165). In addition, ACE2 C-terminus is homologous to collectrin and is responsible for the trafficking of the neutral amino acid transporter SL6A19 to the plasma membrane of gut epithelial cells via direct interaction, regulating its expression on the cell surface and its catalytic activity (PubMed : 18424768, PubMed : 19185582).. (Microbial infection) Acts as a receptor for human coronaviruses SARS-CoV and SARS-CoV-2, as well as human coronavirus NL63/HCoV-NL63.. Isoform 2. Non-functional as a carboxypeptidase.. Isoform 2. (Microbial infection) Non-functional as a receptor for human coronavirus SARS-CoV-2.
