All three Navigators are present in neurite extensions in neurons and neuroblastoma cells, and Nav1 is especially enriched in distal ends of neurites, in growth cones, and at branch points (Martinez-Lopez et al., 2005; Muley et al., 2008; van Haren et al., 2009, 2014; Sanchez-Huertas et al., 2020; Powers et al., 2022). This evidence concerns the gene NAV1 and neuroblastoma.
