Abstract

The human complement system is one of the principal effector systems of innate immunity and consists of more than 30 serum and cell surface proteins. Most complement components show a striking modular structure, and evolutionary studies indicate development from a simpler system by gene duplications and exon shuffling in the vertebrate lineage.

Keywords:

  • gene duplication;
  • modular structure;
  • innate immunity
