complement C1q subcomponent subunit B isoform 1 precursor [Homo sapiens]

Protein Classification

complement C1q domain-containing protein( domain architecture ID 10476615)

complement C1q domain-containing protein with an N-terminal collagen-like triple helix repeat domain similar to human C1q, which is a collagen-like hexameric glycoprotein, which associates with the proenzymes C1r and C1s to yield C1, the first component of the serum complement system

 115-250 3.96e-58

Complement component C1q domain; Globular domain found in many collagens and eponymously in complement C1q. When part of full length proteins these domains form a 'bouquet' due to the multimerization of heterotrimers. The C1q fold is similar to that of tumour necrosis factor.

 39-88 1.56e-09

Collagen triple helix repeat (20 copies); Members of this family belong to the collagen superfamily. Collagens are generally extracellular structural proteins involved in formation of connective tissue structure. The alignment contains 20 copies of the G-X-Y repeat that forms a triple helix. The first position of the repeat is glycine, the second and third positions can be any residue but are frequently proline and hydroxy-proline. Collagens are post translationally modified by proline hydroxylase to form the hydroxy-proline residues. Defective hydroxylation is the cause of scurvy. Some members of the collagen superfamily are not involved in connective tissue structure but share the same triple helical structure. The family includes bacterial collagen-like triple-helix repeat proteins.
