Immunoglobulin-binding protein EibD

UniProtKB accession:  Q9MCI8

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Binds (in a non-immune fashion) to the Fc portion of human IgA and IgG; binding occurs on the cell surface. Confers the ability to survive exposure to human serum exposure (PubMed:10722621). Binds to the Fc portion of human IgG, IgA and to whole mouse antibodies also via Fc (PubMed:19303642). Upon overexpression cells acquire an extra cell surface layer that forms a zipper-like contact between cells; cells autoagglutinate and form biofilm more readily, suggesting it may play a role in defense against a host (PubMed:21742268).
