[[https://www.uniprot.org/uniprot/WASP_HUMAN WASP_HUMAN]] Effector protein for Rho-type GTPases. Regulates actin filament reorganization via its interaction with the Arp2/3 complex. Important for efficient actin polymerization. Possible regulator of lymphocyte and platelet function. Mediates actin filament reorganization and the formation of actin pedestals upon infection by pathogenic bacteria.<ref>PMID:12235133</ref> <ref>PMID:16275905</ref> <ref>PMID:18650809</ref> [[https://www.uniprot.org/uniprot/ESFU2_ECO57 ESFU2_ECO57]] Required for efficient pedestal formation in host epithelial cells during infection. Acts as an intermediate between Tir (via host BAIAP2) and host WASL/N-WASP. Directly binds and activates WASL/N-WASP, which stimulates actin polymerization and leads to the formation of actin pedestals at the sites of bacterial adhesion (By similarity).
