Protein
M protein, serotype 6
Organism
Streptococcus pyogenes serotype M6 (strain ATCC BAA-946 / MGAS10394)
Function
Mediates the attachment of S.pyogenes to skin epithelial cells through the binding of the human membrane cofactor protein CD46. Also binds to the factor H and factor H-like protein 1. These interactions could contribute to the fact that the M6 protein protects the bacterium from the phagocytosis by regulating the complement activation on the bacterial surface (By similarity).
Similarity
Belongs to the M protein family.
