Neurotrimin localizes to the cell membrane and contains three Ig-like C2-type (immunoglobulin-like) domains. Neurotrimin acts as a glycosylphosphatidylinositol (GPI)-anchored neural cell adhesion molecule. Neurotrimin may promote neurite outgrowth and adhesion via homophilic and heterophilic interactions.Alternative Names: Neurotrimin (NTM), also known as IgLON family member 2, IGLON2, HNT and NTRI, is a member of the immunoglobulin superfamily and IgLON family.
