Renin


Renin
Renin, in der Niere gebildetes Enzym mit Hormonwirkung, das bei Abnahme der Nierendurchblutung oder niedrigem Natriumspiegel in den Tubulusepithelzellen ins Blut abgegeben wird und das Protein Angiotensinogen unter Mitwirkung eines weiteren Enzyms, in das Peptid Angiotensin umwandelt. Dieses wirkt blutdrucksteigernd und regt die Abgabe von Aldosteron in der Nebennierenrinde an.
