basic FUNCTION	alpha-N-neuraminide-alpha-2,8-sialyltransferase (glycosylation), facilitating neurite outgrowth
	catalyzing the polycondensation of alpha-2,8-linked sialic acid required for the synthesis of polysialic acid present on the embryonic neural cell adhesion molecule (N-CAM), necessary for plasticity of neural cells
