生化/生理作用

Mca-APK(Dnp)-OH is a widely used fluorescent substrate for angiotensin-converting enzyme 2 (ACE2 cleaves between P & K). Proteolytic cleavage separates 7-methoxycoumarin-4-acetyl (Mca) from the fluorescence-quenching group 2,4-dinitrophenyl (Dnp), resulting in increased Mca fluorescence (Ex: 320-328 nm, Em: 405-420 nm). The fluorescence increase over background upon Mca-APK(Dnp) cleavage is more than 14-fold higher than that of Mca-YVADAPK(Dnp), while only Mca-YVADAPK(Dnp), but not Mca-APK(Dnp), can also be used for assessing caspase-1 (ICE) activity.

The kidney is an important target of the renin-ANG-aldosterone system (RAAS). To date, several studies have demonstrated the existence of a local RAAS in various tissues, including the renal tissue. The mineralocorticoid aldosterone is known to play a critical role

Pancreatic digestive enzymes present in meconium might be responsible for meconium-induced lung injury. The local Renin Angiotensin System plays an important role in lung injury and inflammation. Particularly, angiotensin converting enzyme-2 (ACE-2) has been identified as a protective lung enzyme against

Mid-life hypertension and cerebrovascular dysfunction are associated with increased risk of later life dementia, including Alzheimer's disease (AD). The classical renin-angiotensin system (cRAS), a physiological regulator of blood pressure, functions independently within the brain and is overactive in AD. cRAS-targeting

ACE2 is a monocarboxypeptidase which generates Angiotensin (1-7) from Angiotensin II (1-8). Attempts to target the kidney Renin Angiotensin System using native ACE2 to treat kidney disease are hampered by its large molecular size, 100 kDa, which precludes its glomerular
