該基因編碼iglon（lamp，obcam，ntm）家族的一個成員，iglon（lamp，obcam，ntm）家族的免疫球蛋白（ig）結構域含有糖基磷脂酰肌醇（gpi）錨定的細胞粘附分子。編碼蛋白可能通過一種親和力機制促進神經突起的生長和粘附該基因與11號染色體上的一個相關家族成員阿片結合蛋白/細胞粘附分子樣（opcml）緊密相連。已發現該基因編碼不同亞型的多個轉錄變體。
This gene encodes a member of the IgLON (LAMP, OBCAM, Ntm) family of immunoglobulin (Ig) domain-containing glycosylphosphatidylinositol (GPI)-anchored cell adhesion molecules. The encoded protein may promote neurite outgrowth and adhesion via a homophilic mechanism. This gene is closely linked to a related family member, opioid binding protein/cell adhesion molecule-like (OPCML), on chromosome 11. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2009]
