Function
SLL11_STAAU Secreted protein that plays a role in the inhibition of host immune system. Targets myeloid cells such as monocytes or granulocytes through binding with sialyllactosamine-containing glycoproteins (PubMed:18045383). Prevents initial rolling of neutrophils toward the site of infection by interacting with host SELPLG (PubMed:18045383). Disrupts neutrophil motility by induction of cell adhesion via interacting with glycans but independently of SELPLG (PubMed:30862940).[1] [2]
