该基因产物属于Neulxin家族，其成员在脊椎动物神经系统中起到细胞粘附分子和受体的作用。这种蛋白质，像其他NeRuxin蛋白，含有表皮生长因子重复序列和laminin G结构域。此外，它还包括F5/8型C结构域、discoidin/neuropilin-和fibrinogen样结构域以及血栓反应蛋白N-末端样结构域[由RefSeq提供，2008年7月]
This gene product belongs to the neurexin family, members of which function in the vertebrate nervous system as cell adhesion molecules and receptors. This protein, like other neurexin proteins, contains epidermal growth factor repeats and laminin G domains. In addition, it includes an F5/8 type C domain, discoidin/neuropilin- and fibrinogen-like domains, and thrombospondin N-terminal-like domains. [provided by RefSeq, Jul 2008]
