CC -!- FUNCTION: A cytochrome P450 monooxygenase involved in the metabolism of
CC endogenous oxysterols and steroid hormones, including neurosteroids
CC (PubMed:10588945, PubMed:24491228). Mechanistically, uses molecular
CC oxygen inserting one oxygen atom into a substrate, and reducing the
CC second into a water molecule, with two electrons provided by NADPH via
CC cytochrome P450 reductase (CPR; NADPH-ferrihemoprotein reductase)
CC (PubMed:10588945, PubMed:24491228). Catalyzes the hydroxylation of
CC carbon hydrogen bonds of steroids with a preference for 7-alpha
CC position (PubMed:10588945, PubMed:24491228). Usually metabolizes
CC steroids carrying a hydroxy group at position 3, functioning as a 3-
CC hydroxy steroid 7-alpha hydroxylase (PubMed:24491228). Hydroxylates
CC oxysterols, including 25-hydroxycholesterol and (25R)-cholest-5-ene-
CC 3beta,26-diol toward 7-alpha hydroxy derivatives, which may be
CC transported to the liver and converted to bile acids (PubMed:9802883,
CC PubMed:10588945). Via its product 7-alpha,25-dihydroxycholesterol, a
CC ligand for the chemotactic G protein-coupled receptor GPR183/EBI2,
CC regulates B cell migration in germinal centers of lymphoid organs, thus
CC guiding efficient maturation of plasma B cells and overall antigen-
CC specific humoral immune response (By similarity). 7-alpha hydroxylates
CC neurosteroids, including 3beta-hydroxyandrost-5-en-17-one
CC (dehydroepiandrosterone) and pregnenolone, both involved in
CC hippocampus-associated memory and learning (PubMed:24491228).
CC Metabolizes androstanoids toward 6- or 7-alpha hydroxy derivatives
CC (PubMed:24491228). {ECO:0000250|UniProtKB:Q60991,

CC spasticity of the lower limbs. Rate of progression and the severity of
CC symptoms are quite variable. Initial symptoms may include difficulty
CC with balance, weakness and stiffness in the legs, muscle spasms, and
CC dragging the toes when walking. In some forms of the disorder, bladder
CC symptoms (such as incontinence) may appear, or the weakness and
CC stiffness may spread to other parts of the body.
