Gene Information

human ... C1QB(713)

General description

Anti-C1QB Antibody detects endogenous levels of total C1QB protein.
The C1QB (complement C1q B chain) gene is mapped to human chromosome 1p36.12 and codes for the subcomponent of C1q protein, which is part of C1 complex of the classical pathway. The encoded protein is predominantly expressed in neurons and glia. It is localized to the growing synapses. The encoded protein is a hexameric molecule consisting of three distinct types of 18 polypeptide chains.

Immunogen

The antiserum was produced against synthesized peptide derived from human C1QB.

Immunogen Range: 161-210

Biochem/physiol Actions

The protein encoded by C1QB (complement C1q B chain) gene is involved in synapse formation and offers neuroprotection in the central nervous system. In response to a number of immune and nonimmune ligands, C1q protein activates proteases C1r and C1s in order to trigger classical complement pathway. C1q protein is regarded as a major component of the humoral innate immune defense. C1q carries out opsonophagocytosis, inflammation, and cytolysis to eliminate pathogenic microorganism and harmful apoptotic cells. Mutations in the gene causes systemic lupus erythematosus. Variation in the gene is also linked to rheumatoid schizophrenia, arthritis, amyloidotic polyneuropathy, metastasis of cancer.
