CC -!- FUNCTION: Cell surface-associated protein implicated in virulence by
CC promoting bacterial attachment to both alpha- and beta-chains of human
CC fibrinogen and inducing the formation of bacterial clumps.
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Secreted, cell wall {ECO:0000255|PROSITE-
CC ProRule:PRU00477}; Peptidoglycan-anchor {ECO:0000255|PROSITE-
CC ProRule:PRU00477}. Note=Anchored to the cell wall by sortase A (By
CC similarity). {ECO:0000250|UniProtKB:Q2FUY2}.
CC -!- DOMAIN: The Asp/Ser-rich domain functions as a stalk to allow the
CC ligand binding domain to be displayed in a functional form on the cell
CC surface. {ECO:0000250}.
CC -!- PTM: Proteolytically cleaved by aureolysin (aur). This cleavage leads
CC to the inactivation of ClfB (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the serine-aspartate repeat-containing protein
CC (SDr) family. {ECO:0000305}.
