Complement Clq

The NCI domain of type VIII collagen is important for trimerization. ACRP30/adiponectin, a member of the complement Clq family of proteins,and the type X collagen NCI domain have similar structures as the NCI domain of type VIII collagen however, the type Vlll collagen NCI trimer lacks the buried calcium cluster found in the type X collagen NCI trimer. The crystal structure of this domain has similarity to the TNF (tumor necrosis factor) family of proteins (PDB accession number 1091). ...
