Human peripheral myelin protein-22 carries the L2/HNK-1 carbohydrate adhesion epitope

J Neurochem. 1993 Nov;61(5):1961-4. doi: 10.1111/j.1471-4159.1993.tb09840.x.

Abstract

Molecular genetic studies have established that mutations in the gene encoding the 22-kDa peripheral myelin protein (PMP-22) are responsible for hereditary peripheral neuropathies in the trembler mouse and in a subset of humans with Charcot-Marie-Tooth disease, type 1a. The function of the PMP-22 protein remains unknown. Several studies on myelin proteins in the PNS have indicated that the L2/HNK-1 epitope, which is believed to be both a ligand for cellular adhesion and a target for autoimmune monoclonal IgM neuritis, may be found on heretofore unidentified proteins with a molecular mass of 19-28 kDa. In this report, we provide immunological evidence that at least one of these proteins is PMP-22.
