功能C1q associates with the proenzymes C1r and C1s to yield C1, the first component of the serum complement system. The collagen-like regions of C1q interact with the Ca(2+)-dependent C1r(2)C1s(2) proenzyme complex, and efficient activation of C1 takes place on interaction of the globular heads of C1q with the Fc regions of IgG or IgM antibody present in immune complexes.
疾病相关Defects in C1QA are a cause of complement component C1q deficiency (C1QD) [MIM:613652]. A rare defect resulting in C1 deficiency and impaired activation of the complement classical pathway. C1 deficiency generally leads to severe immune complex disease with features of systemic lupus erythematosus and glomerulonephritis.
序列相似性Contains 1 C1q domain.
Contains 1 collagen-like domain.
翻译后修饰O-linked glycans consist of Glc-Gal disaccharides bound to the oxygen atom of post-translationally added hydroxyl groups.

- C1qa antibody
- C1QA_HUMAN antibody
- C1QB antibody
C1q isolated from the NHS. This antibody reacts with the Human C1q complement. Traces of contaminating antibodies have been removed by solid phase absorption with human plasma proteins. This antibody is well suited for tissue section staining but may also be used for other applications.
ab4223, staining C1q in CHO-K1 cells transfected with M1-AQP4 or M23-AQP4 by Immunocytochemistry/ Immunofluorescence.
Cells were incubated at room temperature with recombinant monoclonal NMO antibody and 120 µg/ml human C1q protein (ab96363). Cells were washed with PBS, fixed in paraformaldehyde and permeabilized with 0.1% Triton X-100. Cells were blocked with 1% BSA for 30 min and incubated for 60 min with primary antibody against C1q (ab4223) at 1/200 dilution.
