Description:
Carboxypeptidase which converts angiotensin I to angiotensin 1-9, a peptide of unknown function, and angiotensin II to angiotensin 1-7, a vasodilator. Also able to hydrolyze apelin-13 and dynorphin-13 with high efficiency. May be an important regulator of heart function. In case of human coronaviruses SARS and HCoV-NL63 infections, serve as functional receptor for the spike glycoprotein of both coronaviruses.

Research Backgrounds

Function:

Carboxypeptidase which converts angiotensin I to angiotensin 1-9, a peptide of unknown function, and angiotensin II to angiotensin 1-7, a vasodilator. Also able to hydrolyze apelin-13 and dynorphin-13 with high efficiency. By cleavage of angiotensin II, may be an important regulator of heart function. By cleavage of angiotensin II, may also have a protective role in acute lung injury (By similarity). Plays an important role in amino acid transport by acting as binding partner of amino acid transporter SL6A19 in intestine, regulating trafficking, expression on the cell surface, and its catalytic activity.

(Microbial infection) Acts as a receptor for SARS coronavirus/SARS-CoV.

(Microbial infection) Acts as a receptor for Human coronavirus NL63/HCoV-NL63.

PTMs:

N-glycosylation on Asn-90 may limit SARS infectivity.

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

Subcellular Location:

Secreted.

Cell membrane>Single-pass type I membrane protein. Cytoplasm.

Tissue Specificity:

Expressed in endothelial cells from small and large arteries, and in arterial smooth muscle cells (at protein level). Expressed in lung alveolar epithelial cells, enterocytes of the small intestine, Leydig cells and Sertoli cells (at protein level). Expressed in the renal proximal tubule and the small intestine (at protein level). Expressed in heart, kidney, testis, and gastrointestinal system.

Subunit Structure:

Interacts with ITGB1. Interacts with the catalytically active form of TMPRSS2. Interacts with SLC6A19; this interaction is essential for expression and function of SLC6A19 in intestine (By similarity).

(Microbial infection) Interacts with SARS coronavirus/SARS-CoV.

(Microbial infection) Interacts with Human coronavirus NL63/HCoV-NL63 spike glycoprotein.

Family&Domains:

Belongs to the peptidase M2 family.
