Plays a role in the recycling mechanism in neurons of multiple receptors and acts at the level of early endosomes to promote sorting of receptors toward a recycling pathway. Endocytosed from the cell surface, thus enters into early endosomes, trafficks to late endosomes and degradates in lysosomes (By similarity). Found in both stationary and motile endosomes. A previous study supports a type I membrane protein topology (By similarity). Belongs to the NSG family.
