Summary: Predicted to enable Hsp70 protein binding activity; heme binding activity; and monooxygenase activity. Predicted to be involved in cholesterol catabolic process and steroid biosynthetic process. Located in mitochondrial inner membrane. Is expressed in several structures, including central nervous system; liver; male reproductive gland or organ; metanephros; and retina.

High expression of cytochrome P450 family 27 subfamily A member 1 (CYP27A1), the enzyme responsible for the synthesis of 27-Hydroxycholesterol (27HC), is associated with decreased progression free survival for ovarian cancer. ID8 tumor cell grafts are unable to effectively establish in CYP27A1-/- mice, indicating involvement of the host environment. Tumors from mice treated with 27HC had altered myeloid cell composition.

7KCh up-regulated IL-1betamRNA, TNF-alphamRNA, IL-6 mRNA, and IL-1beta secretion of RPE. U0126, a MEK1/2 inhibitor, down regulated the expression of these inflammation factors. Our findings may help elucidate the potential role of 7KCh in the pathogenesis of AMD.

In het mice, RIF had no effect on plasma lipids composition, CYP27A1 activity, and atherosclerotic plaque development, despite a reduction in cholesterol absorption. In conclusion, the antiatherogenic effect of Cyp3a11 induction by RIF was also dependent on Cyp27a1 expression.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
