Extracellular fibrinogen binding protein C terminal
This domain family is found in bacteria, and is approximately 70 amino acids in length. There is a conserved VLK sequence motif. It is the C terminal domain of bacterial extracellular fibrinogen binding protein. It contains a helical motif involved in complement regulation. This motif binds to complement and changes its conformation to a form which cannot activate downstream components of the complement cascade.
