This gene encodes an enzyme involved in the conversion of arachidonic acid to 12R-hydroxyeicosatetraenoic acid. Mutations in this gene are associated with nonbullous congenital ichthyosiform erythroderma. [provided by RefSeq, Sep 2015]
GeneCards Summary for ALOX12B Gene
ALOX12B (Arachidonate 12-Lipoxygenase, 12R Type) is a Protein Coding gene. Diseases associated with ALOX12B include Ichthyosis, Congenital, Autosomal Recessive 2 and Congenital Ichthyosiform Erythroderma. Among its related pathways are Metabolism and Immune response IL-23 signaling pathway. Gene Ontology (GO) annotations related to this gene include iron ion binding and arachidonate 12-lipoxygenase activity. An important paralog of this gene is ALOXE3.
UniProtKB/Swiss-Prot for ALOX12B Gene
Non-heme iron-containing dioxygenase that catalyzes the stereo-specific peroxidation of free and esterified polyunsaturated fatty acids generating a spectrum of bioactive lipid mediators. Mainly converts arachidonic acid to (12R)-hydroperoxyeicosatetraenoic acid/(12R)-HPETE and minor stereoisomers. In the skin, acts upstream of ALOXE3 on the lineolate moiety of esterified omega-hydroxyacyl-sphingosine (EOS) ceramides to produce an epoxy-ketone derivative, a crucial step in the conjugation of omega-hydroxyceramide to membrane proteins. Therefore plays a crucial role in the synthesis of corneocytes lipid envelope and the establishment of the skin barrier to water loss. May also play a role in the regulation of the expression of airway mucins.
