FunctionMediates selective neuronal growth and axon targeting. Contributes to the guidance of developing axons and remodeling of mature circuits in the limbic system. Essential for normal growth of the hyppocampal mossy fiber projection.
Tissue specificityExpressed on limbic neurons and fiber tracts as well as in single layers of the superior colliculus, spinal chord and cerebellum.
Sequence similaritiesBelongs to the immunoglobulin superfamily. IgLON family. Contains 3 Ig-like C2-type (immunoglobulin-like) domains.
