CC -!- FUNCTION: Acts as a multifunctional adhesin involved in direct
CC interactions with host epithelial cells and host proteins, including
CC vitronectin, laminin and plasminogen. In addition, interaction with
CC serum vitronectin plays an important role in bacterial serum
CC resistance, and conversion of plasminogen to plasmin at the cell
CC surface aids in immune evasion and contributes to bacterial virulence.
CC Induces a pro-inflammatory epithelial cell response, leading to
CC interleukin-8 (IL-8) secretion and up-regulation of ICAM1.

CC ECO:0000269|PubMed:21881122, ECO:0000269|PubMed:22124123}.
CC -!- SUBUNIT: Homodimer. Interacts with host vitronectin, laminin and
CC plasminogen. Can interact with both immobilized and soluble
CC vitronectin. {ECO:0000269|PubMed:19635912, ECO:0000269|PubMed:21542857,

CC -!- SUBCELLULAR LOCATION: Cell outer membrane
CC {ECO:0000269|PubMed:18069033}; Lipid-anchor {ECO:0000255|PROSITE-
CC ProRule:PRU00303, ECO:0000269|PubMed:18069033}. Cell surface
CC {ECO:0000269|PubMed:18069033}.
CC -!- DISRUPTION PHENOTYPE: Mutant displays a reduced binding to vitronectin,
CC laminin, plasminogen and epithelial cells, and is more sensitive to
CC killing by human serum compared with the wild type.
