The complement component C4 of mammals [PDF]

Biochemical Journal, 1990
Human complement component C4 is coded by tandem genes located in the HLA class III region. The products of the two genes, C4A and C4B, are different in their activity. This difference is due to a degree of ‘substrate’ specificity in the covalent binding reactions of the two isotypes. Mouse also has a duplicated locus, but only one gene produces active

Hepatitis C virus NS3/4A protease inhibits complement activation by cleaving complement component 4. [PDF]

PLoS ONE, 2013
BACKGROUND: It has been hypothesized that persistent hepatitis C virus (HCV) infection is mediated in part by viral proteins that abrogate the host immune response, including the complement system, but the precise mechanisms are not well understood.

Increased activation product of complement 4 protein in plasma of individuals with schizophrenia

Translational Psychiatry, 2021
Structural variation in the complement 4 gene (C4) confers genetic risk for schizophrenia. The variation includes numbers of the increased C4A copy number, which predicts increased C4A mRNA expression.
