Superfamily: Inverse autotransporter, beta-domain

This superfamily includes a beta-barrel porin-like domain found in intimins, invasins and other inverse autotransporters PMID:22658748,PMID:25596886. 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.

Intimin is believed to mediate adherence and it is necessary for the production of attaching and effacing lesions on tissue culture cells PMID:2172966. Invasin is a protein that allows enteric bacteria to penetrate cultured mammalian cells PMID:3304658. The entry of invasin in the cell is mediated by binding several beta-1 chain integrins PMID:10514372.
