CC   -!- FUNCTION: Plays a role in retinoic acid metabolism. Acts on retinoids,
CC       including all-trans-retinoic acid (RA) and its stereoisomer 9-cis-RA
CC       (preferred substrate).
CC   -!- COFACTOR:
CC       Name=heme; Xref=ChEBI:CHEBI:30413; Evidence={ECO:0000250};
CC   -!- INTERACTION:
CC       Q6V0L0; Q96BD6: SPSB1; NbExp=2; IntAct=EBI-25602589, EBI-2659201;
CC   -!- SUBCELLULAR LOCATION: Membrane {ECO:0000305}; Single-pass membrane
CC       protein {ECO:0000305}.
CC   -!- TISSUE SPECIFICITY: Detected in most tissues at very low level.
CC       {ECO:0000269|PubMed:14532297}.
CC   -!- INDUCTION: By retinoic acid. {ECO:0000269|PubMed:14532297}.
CC   -!- DISEASE: Focal facial dermal dysplasia 4 (FFDD4) [MIM:614974]: A form
CC       of focal facial dermal dysplasia, a group of developmental defects
CC       characterized by bitemporal or preauricular skin lesions resembling
CC       aplasia cutis congenita. Skin defects occur at the sites of facial
CC       fusion during embryogenesis, with temporal lesions situated at the
CC       junction between the frontonasal and maxillary facial prominences, and
CC       preauricular lesions at the meeting point of the maxillary and
CC       mandibular prominences. The ectodermal lesions show consistent
CC       histologic abnormalities: atrophy and flattening of the epidermis,
CC       replacement of the dermis by loose connective tissue, reduced levels of
CC       fragmented elastic tissue and absence of the subcutaneous tissues and
CC       adnexal structures. FFDD4 is characterized by isolated, preauricular
CC       skin lesions. {ECO:0000269|PubMed:23161670}. Note=The disease is caused
CC       by variants affecting the gene represented in this entry.
CC   -!- SIMILARITY: Belongs to the cytochrome P450 family. {ECO:0000305}.
