Entrez Gene summary for C1QB Gene:
This gene encodes a major constituent of the human complement subcomponent C1q. C1q associates with C1r and C1s in
order to yield the first component of the serum complement system. Deficiency of C1q has been associated with
lupus erythematosus and glomerulonephritis. C1q is composed of 18 polypeptide chains: six A-chains, six B-chains,
and six C-chains. Each chain contains a collagen-like region located near the N terminus and a C-terminal
globular region. The A-, B-, and C-chains are arranged in the order A-C-B on chromosome 1. This gene encodes the
B-chain polypeptide of human complement subcomponent C1q (provided by RefSeq, Jul 2008)

GeneCards Summary for C1QB Gene:
C1QB (complement component 1, q subcomponent, B chain) is a protein-coding gene. Diseases associated with C1QB include c1q deficiency, and cervical adenitis. GO annotations related to this gene include protein homodimerization activity. An important paralog of this gene is C1QTNF6.

UniProtKB/Swiss-Prot: C1QB_HUMAN, P02746
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
