CATEGORY

structural protein , transport channel

SUBCELLULAR LOCALIZATION

plasma membrane,junction,gap

basic FUNCTION	having connexon channel activity, and involved in cell communication
	playing a key role in central myelination and is and is involved in peripheral myelination in humans
	functional role of GJC2 and GJB6 for interastrocytic, interoligodendrocytic, and panglial coupling, and both connexins are required for maintenance of myelin
