这个基因编码一个神经元细胞表面蛋白家族的成员该家族成员可作为β-奈鲁星的剪接位点特异性配体，并可能参与中枢神经系统突触的形成和重塑。[由RefSeq提供，2008年7月]
This gene encodes a member of a family of neuronal cell surface proteins. Members of this family may act as splice site-specific ligands for beta-neurexins and may be involved in the formation and remodeling of central nervous system synapses. [provided by RefSeq, Jul 2008]
