Effector proteins function to alter host cell physiology and promote bacterial survival in host tissues. Secreted via type III secretion system 2 (SPI-2 TTSS), and delivered into the host cytoplasm. Localizes to the Salmonella-containing vacuole (SCV) at early time points following invasion and subsequently traffics away from the SCV along Salmonella-induced filaments (Sifs) in epithelial cells. Belongs to the Sif family.
