Domain

The cytoplasmic tail contains several linear motifs such as LIR, PDZ-binding, PTB and endocytic sorting signal motifs that would allow interaction with proteins that mediate endocytic trafficking and autophagy.

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. 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. Also removes the C-terminal residue from three other vasoactive peptides, neurotensin, kinetensin, and des-Arg bradykinin, but is not active on bradykinin. Also cleaves other biological peptides, such as apelins, casomorphins and dynorphin A (By similarity). By cleavage of angiotensin II, may be an important regulator of heart function (PubMed:12075344, PubMed:12967627). By cleavage of angiotensin II, may also have a protective role in acute lung injury (PubMed:16001071). Plays an important role in amino acid transport by acting as binding partner of amino acid transporter SLC6A19, regulating its trafficking on the cell surface and its activity (PubMed:18424768, PubMed:19185582, PubMed:22677001).

Post-translational modifications

Proteolytic cleavage by ADAM17 generates a secreted form. Also cleaved by serine proteases: TMPRSS2, TMPRSS11D and HPN/TMPRSS1 (By similarity).

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. 'Lys-48'-linked deubiquitinated by USP50 on the Lys-788; leading to its stabilization.

Sequence similarities

Belongs to the peptidase M2 family.

Tissue specificity

Expressed in heart, kidney and forebrain (at protein level). Expressed in the small intestine, with expression in the intestinal brush border (at protein level) (PubMed:19185582, PubMed:22677001). Ubiquitously expressed, with highest levels in ileum, kidney and lung. In lung, expressed on vascular endothelial and airway epithelial cells. Also expressed at high levels in lung secretory club and goblet cells as well as in alveolar type 2 cells (PubMed:32425701).
