General annotation (Comments)

Function

Cell surface-associated protein implicated in virulence by promoting bacterial attachment to both alpha- and beta-chains of human fibrinogen and inducing the formation of bacterial clumps By similarity.

Subcellular location

Secretedcell wall; Peptidoglycan-anchor Potential.

Domain

The Asp/Ser-rich domain functions as a stalk to allow the ligand binding domain to be displayed in a functional form on the cell surface By similarity.

Post-translational modification

Proteolytically cleaved by aureolysin (aur). This cleavage leads to the inactivation of ClfB By similarity.

Sequence similarities

Belongs to the serine-aspartate repeat-containing protein (SDr) family.
