1/100 - 1/250. Antigen retrieval is recommended; heat up to 98 °C, below boiling, and then let cool for 10-20 minutes. The use of an HRP/AP polymerized secondary antibody is recommended.
Application notesIs unsuitable for Flow Cyt or ICC.
FunctionCarboxypeptidase 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.
Tissue specificityExpressed in endothelial cells from small and large arteries, and in arterial smooth muscle cells. Expressed in lung alveolar epithelial cells, enterocytes of the small intestine, Leydig cells and Sertoli cells (at protein level). Expressed in heart, kidney, testis, and gastrointestinal system.
Sequence similaritiesBelongs to the peptidase M2 family.
Post-translational modificationsN-glycosylation on Asn-90 may limit SARS infectivity.
