>TIGR00929 VirB4_CagE type IV secretion/conjugal transfer ATPase, VirB4 family; InterPro: IPR004346 This family includes the Helicobacter pylori protein CagE (see examples), which together with other proteins from the cag pathogenicity island (PAI), encodes a type IV transporter secretion system. The precise role of CagE is not known, but studies in animal models have shown that it is essential for pathogenesis in Helicobacter pylori induced gastritis and peptic ulceration . Indeed, the expression of the cag PAI has been shown to be essential for stimulating human gastric epithelial cell apoptosis in vitro . Similar type IV transport systems are also found in other bacteria. This family includes proteins from the trb and Vir conjugal transfer systems in Agrobacterium tumefaciens and homologues of VirB proteins from other species.; GO: 0005524 ATP binding.
