| − | |'''Renin'''
| |
| − | |This enzyme forms a vital part of theRenin-Angiotensin-Aldosterone System]], a complex system of hormones and enzymes which act to raise blood pressure when stimulated by hypotension.
| |
| − | Renin is the enzyme required for the creation of the hormone ''angiotensin''.

| |
| − | |Also known as ''Active Vitamin D3'', or ''1-25-Dihydroxyvitamin D3'', Calcitriol is vital for [[Calcium|calcium homeostasis]], and acts to raise plasma calcium levels. Within the kidney, vitamin D from dietary sources or the skin is 'activated' by hydroxylation.

| − | ==Renin==
| |
| − | | |
| − | A proteolytic enzyme synthesised in the kidney. Renin affects blood pressure indirectly and is part of the first stage of the [[Renin Angiotensin Aldosterone System| renin-angiotensin-aldosterone-system]]. Its effects are through its activation of this system by the conversion of angiotensinogen to angiotensin 1.

| − | ==Erythropoietin==
| |
| − | | |
| − | Erythropoietin is a glycoprotein hormone produced in the kidneys in adult life. Its function is beyond the scope of this section and more information can be found on [[Erythropoiesis#Regulation|regulatioon of erythropoiesis]].

| − | ==Vitamin D==
| |
| − | | |
| − | The [[Calcium#Active Vitamin D Synthesis|activation of vitamin D]] is regulated by the kidneys under the influence of another hormone, [[Calcium#Parathyroid Hormone (PTH)|PTH]].
