This domain is found at the C-terminal end of Cell invasion protein SipA (Salmonella Invasion protein A) from Salmonella typhimurium. SipA actin-binding protein that interferes with host cell actin cytoskeleton, and reduce the critical concentration for the formation of F-actin, contributing to bacterial invasion. This domain adopts a a compact, heart-shaped fold dominated by a helical secondary structure. It is responsible for the actin-binding and polymerisation activities of the protein [1,2].	Domain
