Function
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. -
Involvement in disease
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. -
Sequence similarities
Contains 1 C1q domain.
Contains 1 collagen-like domain. -
Post-translational

Positive staining on P90 Wild-type mouse, and no staining on P90 C1qa Knockout Mouse . Primary antibody was applied at a dilution of 1/500 and anti-VGLUT1 antibody. Secondary antibodies including goat anti rabbit IgG (H+L) highly cross-adsorbed Alexa Fluor 594 and goat anti guinea pig IgG (H+L) highly cross-adsorbed Alexa Fluor 488 were also employed at a dilution of 1/500.
