This domain family is found in bacteria, and is approximately 60 amino acids in length. The family is found in association with Pfam:PF00560, Pfam:PF08191, Pfam:PF09479. There are two completely conserved residues (I and F) that may be functionally important. Internalin mediates bacterial adhesion and invasion of epithelial cells in the human intestine through specific interaction with its host cell receptor E-cadherin. This family is the N terminal of internalin, the cap domain of the protein. The cap domain is conserved between different internalin types. The cap domain does not interact with E cadherin, therefore its function is presumably structural: capping the hydrophobic core.	Domain
