Gene information for C1QA (Homo sapiens)
(Information is obtained from NCBI Gene database)
Entrez gene ID712
Official gene symbolC1QA
Full namecomplement component 1, q subcomponent, A chain
Aliases,-,
Gene summaryThis 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 A-chain polypeptide of human complement subcomponent C1q. [provided by RefSeq]
