该基因编码WWC蛋白质家族的一个成员，也包括WWC1（kibra）基因产物和WWC2基因产物。由该基因编码的蛋白质包含c2结构域，已知该结构域介导相关wwc1基因产物中的同二聚体。[由RefSeq提供，2011年9月]
This gene encodes a member of the WWC family of proteins, which also includes the WWC1 (KIBRA) gene product and the WWC2 gene product. The protein encoded by this gene includes a C2 domain, which is known to mediate homodimerization in the related WWC1 gene product. [provided by RefSeq, Sep 2011]
