rtx toxins in "vibrio" bacteria represent an early discovery in rtx toxin research, but were only recently discovered to belong to a separate class of rtx toxins called martx toxins. in "vibrio cholerae" the "martx" gene encodes six proteins: the martx toxin (rtxa), an acyltransferase (rtxc), a membrane fusion protein (rtxd), two abc-transporters (rtxb and rtxe), and one protein with unknown function. rtxa is a virulence factor involved in cholera which facilitates colonization of "v. cholerae" the small intestine. rtxa causes destruction of the actin cytoskeleton in host cells through g-actin modification and destruction of rho gtpases. the toxin contains four functional domains: an actin cross-linking domain (acd), a rho-inactivating domain (rid), a cysteine protease domain (cpd), and an αβ-hydrolase. in "v. cholerae" infection, the cpd binds to inositol hexakisphosphate (insp, phytic acid) inside eukaryotic host cells. this binding activates the autoproteolytic cpd which cleaves the martx protein into smaller independent proteins each containing only one of the effector domains acd, rid, and αβ-hydrolase. this allows each effector to act independently within the host cell, this increases the effects of rtxa because the acd and rid function in different locations within the cell. acd cross-links monomeric g-actin in the host cell cytosol, preventing formation of actin microfilament, a major component of the cytoskeleton. rid inactivates membrane bound rho-gtpases, which are regulators of cytoskeleton formation.

actin-binding protein





















































actin-binding protein (also known as abp) are proteins that bind to actin. this may mean ability to bind actin monomers, or polymers, or both.





















































many actin-binding proteins, including α-actinin, β-spectrin, dystrophin, utrophin and fimbrin, do this through the actin-binding calponin homology domain.





















































this is a list of actin-binding proteins in alphabetical order.
