The protein encoded by this gene belongs to the angiotensin-converting enzyme family of dipeptidyl carboxydipeptidases and has considerable homology to human angiotensin 1 converting enzyme. This secreted protein catalyzes the cleavage of angiotensin I into angiotensin 1-9, and angiotensin II into the vasodilator angiotensin 1-7. ACE2 is known to be expressed in various human organs, and its organ- and cell-specific expression suggests that it may play a role in the regulation of cardiovascular and renal function, as well as fertility. In addition, the encoded protein is a functional receptor for the spike glycoprotein of the human coronavirus HCoV-NL63 and the human severe acute respiratory syndrome coronaviruses, SARS-CoV and SARS-CoV-2, the latter is the causative agent of coronavirus disease-2019 (COVID-19). Multiple splice variants have been found for this gene and the dACE2 (or MIRb-ACE2) splice variant has been found to be interferon inducible. [provided by RefSeq, Nov 2020].

血管紧张素转化酶2(英語:Angiotensin-converting enzyme 2,ACE2;人類的ACE2常被稱為hACE2)在人類基因組中X染色體上的基因編碼,是一種表現於肺、動脈、心臟、腎臟與腸道等組織細胞表面的膜蛋白,為血管紧张素Ⅰ转化酶(ACE)的一個。 ACE2有切割多肽的功能,其多肽酶結構域位於細胞膜外側,一般在細胞膜上作用,可被切割後脫離細胞、自組織間移除。ACE2可分別將血管紧张素I和血管紧张素II轉化为和,因而在心血管組織中有抗氧化與抗發炎等功能,在肺臟中可避免肺組織的損傷,在骨骼肌中或许能抑制肌肉纖維化。ACE2的表現可緩解許多心血管疾病的症狀,其表現量的下降則與這些疾病有相關性,有研究嘗試開發體外合成的人重組ACE2(rhACE2)為這些疾病的一種藥物。除切割多肽外,ACE2還有若干和多肽酶無關的功能。 ACE2还被SARS-CoV、SARS-CoV-2(屬乙型冠狀病毒)和人類冠狀病毒NL63(屬甲型冠狀病毒)等冠狀病毒用作感染細胞的受体,這些病毒刺突蛋白的受体结合域(RBD,receptor binding domain)可結合ACE2,進而使病毒進入細胞內。三種病毒的RBD均與ACE2的相同區域結合,但NL63病毒的RBD結構和另兩者差異較大,與ACE2的結合應為趨同演化的結果,且結合力較另外兩種病毒弱。SARS相關病毒也並非皆以ACE2為感染細胞的受體,SARS-CoV-2支系的共祖可能具有和ACE2結合的能力,此支系的病毒又與SARS-CoV支系的病毒發生重組,使部分SARS-CoV相關病毒也獲得此能力。
