Part Description

LP18213-6   Myelin associated glycoprotein
Myelin associated glycoprotein (MAG) is a 100 kDa transmembrane glycoprotein found in the periaxonal membranes of Schwann cells and oligodendrocytes of myelin sheaths. Despite the fact that MAG is a known white matter inhibitor of axonal regeneration and as a receptor for IgM antibodies that demyelinates peripheral nerves, it has important roles that promote normal formation and maintenance of myelinated axons. There are two apparent functions of MAG which are to act as a ligand for an axonal receptor which maintains myelinated axons, and to act as an axonal signal receptor that promotes differentiation, maintenance, and survival of oligodendrocytes. MAG shares an epitope with other glyoconjugates that is the target protein in autoimmune peripheral neuropathy, that is associated with IgM gammopathy which causes the death of oligodendrocytes that is seen in multiple sclerosis.

Change Reason
The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
