background

ACE2 (Angiotensin I Converting Enzyme 2) is a Protein Coding gene. Diseases associated with ACE2 include Severe Acute Respiratory Syndrome and Neurogenic Hypertension.The protein encoded by this gene belongs to the angiotensin-converting enzyme family of dipeptidyl carboxydipeptidases and has considerable homology to human angiotensin 1 converting enzyme. This secreted protein catalyzes the cleavage of angiotensin I into angiotensin 1-9, and angiotensin II into the vasodilator angiotensin 1-7.

molecular weight

The protein has a predicted MW of 86.5 kDa. Due to glycosylation, the protein migrates to 95-110 kDa based on Tris-Bis PAGE result.

Function
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:10969042, PubMed:10924499, PubMed:11815627, PubMed:19021774, PubMed:14504186). 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). {ECO:0000269|PubMed:10924499, ECO:0000269|PubMed:10969042, ECO:0000269|PubMed:11815627, ECO:0000269|PubMed:14504186, ECO:0000269|PubMed:18424768, ECO:0000269|PubMed:19021774, ECO:0000269|PubMed:19185582, ECO:0000269|PubMed:27217402}.; FUNCTION: (Microbial infection) Acts as a receptor for human coronaviruses SARS-CoV and SARS-CoV-2, as well as human coronavirus NL63/HCoV-NL63. {ECO:0000269|PubMed:14647384, ECO:0000269|PubMed:15452268, ECO:0000269|PubMed:15791205, ECO:0000269|PubMed:15897467, ECO:0000269|PubMed:19901337, ECO:0000269|PubMed:24227843, ECO:0000269|PubMed:32142651, ECO:0000269|PubMed:32155444, ECO:0000269|PubMed:32221306, ECO:0000269|PubMed:32225175, ECO:0000269|PubMed:33000221, ECO:0000269|PubMed:33082294, ECO:0000269|PubMed:33432067}.; FUNCTION: [Isoform 2]: Non-functional as a carboxypeptidase. {ECO:0000269|PubMed:33077916}.; FUNCTION: [Isoform 2]: (Microbial infection) Non-functional as a receptor for human coronavirus SARS-CoV-2. {ECO:0000269|PubMed:33077916, ECO:0000269|PubMed:33432184}.

Structure
SUBUNIT: Homodimer (PubMed:32132184). Interacts with the catalytically active form of TMPRSS2 (PubMed:21068237). Interacts with SLC6A19; this interaction is essential for expression and function of SLC6A19 in intestine (By similarity). Interacts with ITGA5:ITGB1 (PubMed:15276642, PubMed:33102950). Probably interacts (via endocytic sorting signal motif) with AP2M1; the interaction is inhibited by phosphorylation of Tyr-781 (PubMed:33436498). Interacts (via PDZ-binding motif) with NHERF1 (via PDZ domains); the interaction may enhance ACE2 membrane residence (PubMed:34189428). {ECO:0000250|UniProtKB:Q8R0I0, ECO:0000269|PubMed:15276642, ECO:0000269|PubMed:21068237, ECO:0000269|PubMed:32132184, ECO:0000269|PubMed:33102950, ECO:0000269|PubMed:33436498, ECO:0000269|PubMed:34189428}.; SUBUNIT: (Microbial infection) Interacts with SARS coronavirus/SARS-CoV spike protein. {ECO:0000269|PubMed:14647384, ECO:0000269|PubMed:15452268, ECO:0000269|PubMed:15791205, ECO:0000269|PubMed:32225175}.; SUBUNIT: (Microbial infection) Interacts with SARS coronavirus-2/SARS-CoV-2 spike protein (via RBD domain). {ECO:0000269|PubMed:32075877, ECO:0000269|PubMed:32132184, ECO:0000269|PubMed:32155444, ECO:0000269|PubMed:32225175, ECO:0000269|PubMed:32753553, ECO:0000269|PubMed:33102950, ECO:0000269|PubMed:33432067, ECO:0000269|PubMed:36228039, ECO:0000269|PubMed:36735681, ECO:0000269|PubMed:36757924}.; SUBUNIT: (Microbial infection) Interacts with human coronavirus NL63 spike protein. {ECO:0000269|PubMed:19901337}.; SUBUNIT: (Microbial infection) Interacts with human coronavirus NL63/HCoV-NL63 spike glycoprotein. {ECO:0000269|PubMed:15897467}.; SUBUNIT: [Processed angiotensin-converting enzyme 2]: (Microbial infection) Interacts with SARS coronavirus-2/SARS-CoV-2 spike protein; the interaction is increased by AVP/Arg-vasopressin with which they may form a complex. {ECO:0000269|PubMed:33713620}.
