Angiotensin I converting enzyme II
This article is a stub. Please help improve this page if you can.
Angiotensin I converting enzyme II or ACE2, also known as ACEH, is part of the renin-angiotensin system, which regulates blood pressure, and the balance of fluids and salts in the body.
Function[edit | edit source]
The ACE2 encoding gene is believed to have a role in the carcardiovascular/circulatory system, kidney function, and fertility.
ACE2 cuts the angiotensin I protein, convert it into angiotensin II.
ME/CFS[edit | edit source]
Lieberman and Bell (1992) found higher serum ACE2 levels in 80% of patients with ME/CFS, compared to 9.4% of controls.
POTS[edit | edit source]
Musafa et al. (2012) found some patients with POTS have "inappropriately high plasma angiotensin II levels", and estimated that these patents had low ACE2 activity.
COVID-19[edit | edit source]
SARS-CoV-2, the virus that causes COVID-19, uses ACE2 receptors to binds to human cell. Yan et al 2020) suggest that blocking ACE2 receptors may potentially prevent SARS-CoV-2 infection.
