Gene: CYP7B1 (cytochrome P450 family 7 subfamily B member 1) Homo sapiens
Symbol: CYP7B1
Name: cytochrome P450 family 7 subfamily B member 1
Description: Predicted to have oxysterol 7-alpha-hydroxylase activity. Predicted to be involved in B cell chemotaxis; bile acid biosynthetic process; and cholesterol homeostasis. Predicted to localize to endoplasmic reticulum membrane. Implicated in congenital bile acid synthesis defect 3 and hereditary spastic paraplegia 5A.
Type: protein-coding
RefSeq Status: REVIEWED
