Vitamin D-24-hydroxylase (24-OHase) is a cytochrome P-450 enzyme that catalyzes the conversion of 25-hydroxyvitamin D3 (25OHD3) and 1α,25-dihydroxyvitamin D3[ 1,25-(OH)2D3] to 24,25-dihydroxyvitamin D3 and 1,24,25-trihydroxyvitamin D3, respectively. A full-length complementary DNA for mouse 24-OHase has now been characterized. The complementary DNA consists of 3309 bp and encodes a protein of 514 amino acids that shows 82% and 95% sequence identity with the human and rat enzymes, respectively. Northern blot analysis of tissues from mice injected with 1,25-(OH)2D3 (24 pmol/g) revealed that the 3.4-kb 24-OHase messenger RNA (mRNA) is most abundant in kidney and intestine, with smaller amounts present in skin, thymus, and bone. RT-PCR and Southern blot analysis detected 24-OHase mRNA in several other tissues including lung, testis, spleen, pancreas, and heart. Intraperitoneal injection of 1,25-(OH)2D3 induced dose- and time-dependent increases in both 24-OHase mRNA abundance and enzyme activity in mouse kidn...
