The vitamin A metabolite, all-trans retinoic acid (atRA), plays an important role in neuronal development, including neurite outgrowth. RAINB1 is an atRA-responsive gene.[7]

The neuron navigator, Is also theorized to play a role in cellular growth and migration[8]. In addition, different isoform variants have been discovered for this gene. Connections have been drawn to Nav2 having an association with human neurocognitive disorders Alzheimer's disease and age-related phenotypes. It has been discussed that future studies of Nav2 could provide crucial information in understanding the pathophysiology of the disease and its related phenotypes[9].
