Entrez Gene Summary for ALOX12B Gene

  • This gene encodes an enzyme involved in the converstion of arachidonic acid to 12R-hydroxyeicosatetraenoic acid. Mutations in this gene are associated with nonbullous congenital ichthyosiform erythroderma. [provided by RefSeq, Jul 2008]

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 Metabolism. GO annotations related to this gene include iron ion binding and arachidonate 12-lipoxygenase activity. An important paralog of this gene is ALOX12.

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.

LX12B_HUMAN
  • Ichthyosis, congenital, autosomal recessive 2 (ARCI2) [MIM:242100]: A form of autosomal recessive congenital ichthyosis, a disorder of keratinization with abnormal differentiation and desquamation of the epidermis, resulting in abnormal skin scaling over the whole body. The main skin phenotypes are lamellar ichthyosis (LI) and non-bullous congenital ichthyosiform erythroderma (NCIE), although phenotypic overlap within the same patient or among patients from the same family can occur. Lamellar ichthyosis is a condition often associated with an embedment in a collodion-like membrane at birth; skin scales later develop, covering the entire body surface. Non-bullous congenital ichthyosiform erythroderma characterized by fine whitish scaling on an erythrodermal background; larger brownish scales are present on the buttocks, neck and legs. {ECO:0000269 PubMed:11773004, ECO:0000269 PubMed:16116617, ECO:0000269 PubMed:19131948, ECO:0000269 PubMed:19890349}. Note=The disease is caused by mutations affecting the gene represented in this entry.
