Human MOG/BTN6/BTNL11 Protein, ECD (Extracellular Domain), Fc-fusion, Recombinant

Description

MOG (myelin oligodendrocyte glycoprotein) is a two-pass type I transmembrane protein belonging to the BTN/MOG family of the immunoglobulin (Ig) superfamily.  MOG contains an Ig-like V-type domain in the first extracelluar region followed by two transmembrane regions and a small second extracellular tail. MOG is found exclusively in the CNS, where it is localized on the surface of myelin and oligodendrogliocyte membranes. The MOG genes are highly conserved in mammals, suggesting an important biological role for this protein.  While the primary molecular function of MOG is not yet known, its likely role with the myelin sheath is either in sheath completion and/or maintenance.  MOG may mediate homophilic cell-cell adhesion. MOG is considered as an autoantigen capable to produce a demyelinating multiple sclerosis (MS)-like disease in experimental animals. Several studies have shown a role for antibodies against MOG in the pathogenesis of MS. The mutation in the MOG gene is associated with Narcolepsy 7 (NRCLP7), a neurological disabling sleep disorder, characterized by excessive daytime sleepiness, sleep fragmentation, symptoms of abnormal rapid-eye-movement sleep, cataplexy, hypnagogic hallucinations, and sleep paralysis.
