  • 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.

    2. We identified a major linear epitope of C1q that is the target of anti-C1q in systemic lupus erythematosus. PMID: 22740328
    3. The susceptibility for schizophrenia was particularly associated with C1QB rs291982 GG genotype. PMID: 21951915
    4. a 2-gene signature consisting of PLEK2 and C1QB led to the best result that correctly classified 93.3% melanoma patients and 90% healthy controls PMID: 21698244
    5. The C-terminal globular region of the C1Q B chain may have evolved as a functionally specialized domain or module with distinct binding properties which together with the A and C chains confers versatility and flexibility to the whole C1q molecule. PMID: 12847249
    6. Complementary interacting sites on the C1q globular domain have been precisely defined. Characterization of point mutants suggests a central role for Arg114 and a complementary role for Arg129, Arg163, and His117 of C1Q B chain in the C1q-IgG interaction. PMID: 15034050
    7. The first analysis of C1q by mass spectrometry yields evidence that the B chain moiety of the globular head is involved in the interaction with fucoidan and underscores the particular role of arginine-109 in the charge pattern recognition property of C1q. PMID: 15709773
    8. results suggest that charged residues belonging to the apex of the gC1q heterotrimer (with participation of all three chains) as well as the side of the ghB are crucial for C1q binding to ligands, IgG1, C-reactive protein, and pentraxin 3. PMID: 16566583
    9. No C1q or low molecular weight C1q was detected in sera and no anti-C1q autoantibodies were found. Sequencing of the C1q genes revealed a novel missense mutation (Gly-Arg) in codon 217 of the B chain. PMID: 17513176
