May play a role in developmental myelination of peripheral nerves. Additional isoforms seem to exist. Ubiquitously expressed. Found in the neuroepithelium of the meninges at 8.5 dpc, and in the roof plate of the rhombencephalon at 9.5 dpc. In 12.5 dpc embryos, it is ubiquitously expressed, with a pronounced expression in the neuroepithelium of brain vesicles, the neural tube, the ganglia and the neural layer of the retina. Methylated at Gln-1314 by N6AMT1.
