Protein attributes
| Sequence length | 503 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at transcript level |
General annotation (Comments)
| Function | Catalyzes a rate-limiting step in cholesterol catabolism and bile acid biosynthesis by introducing a hydrophilic moiety at position 7 of cholesterol. Important for cholesterol homeostasis. Ref.4 |
| Catalytic activity | Cholesterol + NADPH + O2 = 7-alpha-hydroxycholesterol + NADP+ + H2O. |
| Cofactor | Heme group By similarity. |
| Pathway | |
| Subcellular location | Endoplasmic reticulum membrane; Peripheral membrane protein. Microsome membrane; Peripheral membrane protein. |
| Induction | Up-regulated by fasting, returns to ground state upon feeding. Up-regulated by experimentally induced diabetes. Down-regulated by insulin treatment. Ref.4 Ref.5 |
| Sequence similarities | Belongs to the cytochrome P450 family. |
