Function
GCAM_MOUSE ACE2_MOUSE 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:19185582, PubMed:18424768, PubMed:22677001).[UniProtKB:Q9BYF1][1] [2] [3] [4] [5] [6]
