Summaries for C4BPB Gene

Entrez Gene Summary for C4BPB Gene

  • This gene encodes a member of a superfamily of proteins composed predominantly of tandemly arrayed short consensus repeats of approximately 60 amino acids. A single, unique beta-chain encoded by this gene assembles with seven identical alpha-chains into the predominant isoform of C4b-binding protein, a multimeric protein that controls activation of the complement cascade through the classical pathway. C4b-binding protein has a regulatory role in the coagulation system also, mediated through the beta-chain binding of protein S, a vitamin K-dependent protein that serves as a cofactor of activated protein C. The genes encoding both alpha and beta chains are located adjacent to each other on human chromosome 1 in the regulator of complement activation gene cluster. Alternative splicing gives rise to multiple transcript variants. [provided by RefSeq, Jul 2008]

GeneCards Summary for C4BPB Gene

C4BPB (Complement Component 4 Binding Protein Beta) is a Protein Coding gene. Diseases associated with C4BPB include Hemolytic Uremic Syndrome, Atypical 1. Among its related pathways are Immune response Lectin induced complement pathway and Pertussis. An important paralog of this gene is CR1.

UniProtKB/Swiss-Prot Summary for C4BPB Gene

  • Controls the classical pathway of complement activation. It binds as a cofactor to C3b/C4b inactivator (C3bINA), which then hydrolyzes the complement fragment C4b. It also accelerates the degradation of the C4bC2a complex (C3 convertase) by dissociating the complement fragment C2a. It also interacts with anticoagulant protein S and with serum amyloid P component. The beta chain binds protein S.
