Bacterial Ig-like, group 1 Proteins that contain this domain are found in a variety of bacterial and phage surface proteins such as intimins. Intimin is a bacterial cell-adhesion molecule that mediates the intimate bacterial host-cell interaction. It contains three domains; two immunoglobulin-like domains and a C-type lectin-like module implying that carbohydrate recognition may be important in intimin-mediated cell adhesion [<cite idref="PUB00014503"/>].
