CC   -!- FUNCTION: Secreted protein that plays a role in the inhibition of host
CC       immune system. Targets myeloid cells such as monocytes or granulocytes
CC       through binding with sialyllactosamine-containing glycoproteins.
CC       Prevents initial rolling of neutrophils toward the site of infection by
CC       interacting with host SELPLG. Disrupts neutrophil motility by induction
CC       of cell adhesion via interacting with glycans but independently of
CC       SELPLG. {ECO:0000250|UniProtKB:A8E1U5}.
CC   -!- SUBUNIT: Homodimer (via its C-terminal domain). Interacts with host
CC       FCAR and SELPLG (via sialyl Lewis X). {ECO:0000250|UniProtKB:A8E1U5}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:Q2G1S8}.
CC   -!- DOMAIN: The C-terminal domain contains a V-shape binding site for
CC       sialyl Lewis X. {ECO:0000250|UniProtKB:Q2G0X7}.
CC   -!- SIMILARITY: Belongs to the staphylococcal/streptococcal toxin family.
CC       {ECO:0000305}.
