CYP24A1 is expressed in tissues which are considered targets for vitamin D, including kidney, intestine and bone. Transcription of the CYP24A1 gene is markedly inducible by 1,25-(OH)2D3 binding to the vitamin D receptor. The gene has a strong, positive vitamin D response element in the promoter. Through regulation of CYP24A1 expression, a negative feedback control system is created to limit the effects of 1,25-(OH)2D3.
