DefinitionThis section has been translated automatically.
ORMDL3 (Orosomucoid like 3) also known as Sphingolipid Biosynthesis Regulator 3, is a protein encoded by the ORMDL3 gene of the same name located on chromosome 17q21.1. Mutations of the ORMDL3 gene are associated with childhood asthma, among others (Moffatt MF et al. 2007).
General informationThis section has been translated automatically.
ORMDL3 plays an inhibitory role in sphingolipid synthesis. It also plays a role in the regulation of Ca2 + levels in the endoplasmic reticulum (ER). ER plays an important role in the generation, signaling, function and storage of intracellular Ca2 +. There are channels that control the release of Ca2 + from the ER into the cytoplasm. Furthermore, certain pumps (sarcoendoplasmic reticulum Ca2 + ATPase = SERCA) return cytoplasmic Ca2 + back into the ER. Dysregulation of Ca2 + plays a key role in various pathological conditions such as asthma and Alzheimer's disease (Green KN et al. (2008). Furthermore, mutations in the ORMDL3 gene are associated with inflammatory diseases like Crohn's disease, type 1 diabetes and rheumatoid arthritis (Kurreeman FA et al. 2012).
