SUBCELLULAR LOCALIZATION

basic FUNCTION	is an important new player in neuronal development that is likely to impact on the neuropathogenesis of HSA21-related disorders including Down Syndrome
	important for accurate oligodendroglial differentiation, influencing their capacity to mature and to myelinate axons
