该基因编码的蛋白质是一种GTPase激活剂，与GTPase CDC42协同作用，负性调节神经元的迁移编码蛋白与跨膜受体ROBO1相互作用，使CDC42失活[由RefSeq提供，2016年9月]
The protein encoded by this gene is a GTPase activator, working with the GTPase CDC42 to negatively regulate neuronal migration. The encoded protein interacts with the transmembrane receptor ROBO1 to inactivate CDC42. [provided by RefSeq, Sep 2016]
