Background Information

Angiotensin-converting enzyme 2 (ACE2) is a type I transmembrane zinc metalloprotease with about 60% homology to ACE, consisting of 805 amino acids including a signal peptide, catalytic domain, membrane anchor, and cytoplasmic tail. ACE2 regulates the renin-angiotensin system by converting angiotensin I to angiotensin 1-9 and angiotensin II to the vasodilator angiotensin 1-7, thus counteracting vasoconstriction and playing a key role in cardiovascular and renal function. ACE2 also serves as the functional receptor for human coronaviruses SARS-CoV, SARS-CoV-2, and HCoV-NL63, facilitating viral entry. Its expression is high in lung, heart, kidney, intestine, testis, and vascular cells. Beyond cardiovascular regulation, ACE2 is involved in respiratory disease pathogenesis, including acute respiratory distress syndrome, and has been linked to diabetes and hypertension. Additionally, its homolog collectrin is implicated in amino acid transport and genetic disorders like Hartnup disease.

Frequently Asked Questions

Why are Recombinant Proteins expressed with epitope tags?

The majority of InnoCyto's recombinantly expressed proteins are engineered with a short, well-characterized peptide sequence (e.g., His-tag, Fc-tag, Flag-tag, or similar) fused to the protein of interest. The tag enables reliable detection, purification, or immobilization of the protein using commercially available anti-tag antibodies or affinity resins, without needing a custom antibody against the native protein.

What types of tagged proteins are best for my application?

Common tag options include His-tag (for affinity purification via Ni-NTA/IMAC and detection via anti-His antibodies), Fc-tag (for use in binding assays, ELISA capture, and dimerization studies), and Flag-tag (for high-specificity detection and immunoprecipitation). Tag choice should be based on your intended workflow — purification-focused work often favors His-tag, while functional binding or capture-based assays often benefit from Fc-tag.

Does the tag affect the protein's biological activity or binding function?

Tag placement (N-terminal vs. C-terminal) and type are selected during design to minimize interference with the protein's native folding and functional binding site, and each tagged protein is validated for activity in relevant binding or functional assays. Product pages indicate the tag location and confirm the functional validation performed for that specific protein.
