General info

Function

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.

Sequence similarities

Belongs to the peptidase M2 family.

Post-translational modifications

N-glycosylation on Asn-90 may limit SARS infectivity.. Proteolytic cleavage by ADAM17 generates a secreted form (PubMed:15983030, PubMed:33713620). Also cleaved by serine proteases: TMPRSS2, TMPRSS11D and HPN/TMPRSS1.. Phosphorylated. Phosphorylation at Tyr-781 probably inhibits interaction with AP2M1 and enables interactions with proteins containing SH2 domains.. Ubiquitinated. Ubiquitinated on Lys-788 via 'Lys-48'-linked ubiquitin (PubMed:36876523). 'Lys-48'-linked deubiquitinated by USP50 on the Lys-788; leading to its stabilization (PubMed:36876523).
