Chains Pfam Accession Pfam Identifier Pfam Description Type Source
I PF02368 Big_2 Bacterial Ig-like domain (group 2) Family
I PF02369 Big_1 Bacterial Ig-like domain (group 1) Domain This family consists of bacterial domains with an Ig-like fold. Members of this family are found in bacterial surface proteins such as intimins and invasins involved in pathogenicity. PFAM PF02369
I PF07979 Intimin_C Intimin C-type lectin domain Domain This domain is found at the C-terminus of intimin. Its structure has been solved and shown to have a C-lectin type of structure [1]. Intimin is a bacterial adhesion molecule involved in intimate attachment of enteropathogenic and enterohemorrhagic Escherichia coli to mammalian host cells. Intimin targets the translocated intimin receptor (Tir), which is exported by the bacteria and integrated into the host cell plasma membrane. PFAM PF07979
T PF03549 Tir_receptor_M Translocated intimin receptor (Tir) intimin-binding domain Domain Intimin and its translocated intimin receptor (Tir) are bacterial proteins that mediate adhesion between mammalian cells and attaching and effacing (A/E) pathogens. A unique and essential feature of A/E bacterial pathogens is the formation of actin-rich pedestals beneath the intimately adherent bacteria and localised destruction of the intestinal brush border. The bacterial outer membrane adhesin, intimin, is necessary for the production of the A/E lesion and diarrhoea. The A/E bacteria translocate their own receptor for intimin, Tir, into the membrane of mammalian cells using the type III secretion system. The translocated Tir triggers additional host signalling events and actin nucleation, which are essential for lesion formation [1]. This family represents the Tir intimin-binding domain (Tir IBD) which is needed to bind intimin and support the predicted topology for Tir, with both N- and C-terminal regions in the mammalian cell cytosol [2].
