    The conserved oligomeric Golgi (COG) complex is an octameric protein complex associated with the Golgi apparatus and is required for proper sorting and glycosylation of Golgi resident enzymes and secreted proteins. Although COG complex function has been extensively studied at the cellular and subcellular levels, its role in animal development mostly remains unknown. Recently, mutations in the components of the COG complex were found to cause abnormal gonad morphogenesis in Caenorhabditis elegans. In C. elegans, the COG complex acts in the glycosylation of an ADAM (a disintegrin and metalloprotease) family protein, MIG-17, which directs migration of gonadal distal tip cells to lead gonad morphogenesis. This is the first link between the COG complex and the function of an ADAM protease that is directly involved in organ morphogenesis, demonstrating the potential of C. elegans as a model system to study COG function in animal development.
