該基因產物屬于Neulxin家族，其成員在脊椎動物神經系統中起到細胞粘附分子和受體的作用。這種蛋白質，像其他NeRuxin蛋白，含有表皮生長因子重復序列和laminin G結構域。此外，它還包括F5/8型C結構域、discoidin/neuropilin-和fibrinogen樣結構域以及血栓反應蛋白N-末端樣結構域[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]
