CC -!- FUNCTION: Extracellular fibrinogen-binding protein that plays an
CC important role in virulence. By interacting with the alpha chain of
CC fibrinogen and its derivative fibrin, enhances a non-functional
CC interaction between fibrinogen and platelets and is responsible for
CC repression of fibrinogen-dependent platelet aggregation. In addition,
CC assembles a fibrinogen protective shield around the bacteria which
CC results in impaired phagocytic clearance by the host. Mechanistically,
CC interacts with host complement C3b deposited on the surface of the
CC bacterium via its C-terminal and then recruits fibrinogen via its N-
CC terminal. {ECO:0000250|UniProtKB:A6QG59}.
CC -!- SUBUNIT: Interacts with host fibrinogen alpha chain/FGA. Interacts with
CC host complement protein C3. {ECO:0000250|UniProtKB:A6QG59}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:A6QG59}.
