Summaries for CYP26C1 Gene

Entrez Gene Summary for CYP26C1 Gene

  • This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This enzyme is involved in the catabolism of all-trans- and 9-cis-retinoic acid, and thus contributes to the regulation of retinoic acid levels in cells and tissues. This gene is adjacent to a related gene on chromosome 10q23.33. [provided by RefSeq, Jul 2008]

GeneCards Summary for CYP26C1 Gene

CYP26C1 (Cytochrome P450 Family 26 Subfamily C Member 1) is a Protein Coding gene. Diseases associated with CYP26C1 include Focal Facial Dermal Dysplasia 4 and Focal Facial Dermal Dysplasia. Among its related pathways are Cytochrome P450 - arranged by substrate type and Metabolism. GO annotations related to this gene include iron ion binding and oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen. An important paralog of this gene is CYP26B1.

UniProtKB/Swiss-Prot for CYP26C1 Gene

  • Plays a role in retinoic acid metabolism. Acts on retinoids, including all-trans-retinoic acid (RA) and its stereoisomer 9-cis-RA (preferred substrate).

Tocris Summary for CYP26C1 Gene

  • Cytochrome P450 (CYP450) enzymes are a diverse group of catalysts that contains 57 members in humans. CYPs are usually membrane-bound and are localized to the inner mitochondrial or endoplasmic reticular membrane. CYPs have oxygenase activity.

  • Focal facial dermal dysplasia 4 (FFDD4) [MIM:614974]: A form of focal facial dermal dysplasia, a group of developmental defects characterized by bitemporal or preauricular skin lesions resembling aplasia cutis congenita. Skin defects occur at the sites of facial fusion during embryogenesis, with temporal lesions situated at the junction between the frontonasal and maxillary facial prominences, and preauricular lesions at the meeting point of the maxillary and mandibular prominences. The ectodermal lesions show consistent histologic abnormalities: atrophy and flattening of the epidermis, replacement of the dermis by loose connective tissue, reduced levels of fragmented elastic tissue and absence of the subcutaneous tissues and adnexal structures. FFDD4 is characterized by isolated, preauricular skin lesions. {ECO:0000269 PubMed:23161670}. Note=The disease is caused by mutations affecting the gene represented in this entry.
