| + | [[http://www.uniprot.org/uniprot/IBPA_HAES2 IBPA_HAES2]] Adenylyltransferase involved in virulence by mediating the addition of adenosine 5'-monophosphate (AMP) to specific tyrosine residue of host Rho GTPases RhoA, Rac and Cdc42. The resulting AMPylation inactivates Rho GTPases, thereby inhibiting actin assembly in infected cells. Probably also acts as a cysteine protease, which may play a central role after invasion of host cell and in virulence. Possible member (with IbpB) of a 2 partner secretion. Probably able to bind bovine epithelial cells (host cells). May participate in the formation of fibrils at the surface of the bacteria.<ref>PMID:9317034</ref> <ref>PMID:12631474</ref> <ref>PMID:19362538</ref> <ref>PMID:20622875</ref> [[http://www.uniprot.org/uniprot/CDC42_HUMAN CDC42_HUMAN]] Plasma membrane-associated small GTPase which cycles between an active GTP-bound and an inactive GDP-bound state. In active state binds to a variety of effector proteins to regulate cellular responses. Involved in epithelial cell polarization processes. Regulates the bipolar attachment of spindle microtubules to kinetochores before chromosome congression in metaphase. Plays a role in the extension and maintenance of the formation of thin, actin-rich surface projections called filopodia. Mediates CDC42-dependent cell migration.<ref>PMID:14978216</ref> <ref>PMID:15642749</ref> <ref>PMID:17038317</ref> | ||
