This is a family of beta-barrel porin-like outer membrane proteins from enteropathogenic Gram-negative bacteria. Intimins and invasins are virulence factors produced by pathogenic Gram-negative bacteria. They carry C-terminal extracellular passenger domains that are involved in adhesion to host cells and N-terminal beta domains that are embedded in the outer membrane. This family represents the beta-barrel porin-like domain in the outer membrane that can be found in intimins, invasins and some inverse autotransporters [1,2].	Domain
