Summary: Enables oxysterol 7-alpha-hydroxylase activity. Involved in B cell chemotaxis and bile acid biosynthetic process. Acts upstream of or within negative regulation of intracellular estrogen receptor signaling pathway; positive regulation of epithelial cell proliferation; and prostate gland epithelium morphogenesis. Predicted to be located in intracellular membrane-bounded organelle. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system; and sensory organ. Human ortholog(s) of this gene implicated in congenital bile acid synthesis defect 3 and hereditary spastic paraplegia 5A. Orthologous to human CYP7B1 (cytochrome P450 family 7 subfamily B member 1).

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.
