| UniProt functional annotation for Q56061 | |||
| UniProt code: Q56061. |
| Organism: | Salmonella typhimurium (strain LT2 / SGSC1412 / ATCC 700720). | |
| Taxonomy: | Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Salmonella. | |
| Function: | Effector proteins function to alter host cell physiology and promote bacterial survival in host tissues. This protein is required for endosomal tubulation and formation of Salmonella-induced filaments (Sifs), which are filamentous structures containing lysosomal membrane glycoproteins within epithelial cells. Sif formation is concomitant with intracellular bacterial replication. {ECO:0000269|PubMed:12010459, ECO:0000269|PubMed:15905402, ECO:0000269|PubMed:18996344}. | |
| Subunit: | Interacts with host PLEKHM2. Interacts with SseJ; the interaction is indirect. {ECO:0000269|PubMed:15905402, ECO:0000269|PubMed:18996344}. | |
| Subcellular location: | Secreted. Host cytoplasm. Host cell membrane. Note=Secreted via type III secretion system 2 (SPI-2 TTSS), and delivered into the host cytoplasm. It associates with membranes and colocalizes with microtubules along the length of Sifs in infected cells. | |
| Domain: | Domains throughout the protein, and not only the N-terminus, are required for secretion and translocation. Both N- and C-terminal domains are also required for formation of tubules. {ECO:0000269|PubMed:16849798}. | |
| Disruption phenotype: | Cells lacking this gene do not produce Sifs in epithelial cells and show attenuated virulence in mice. {ECO:0000269|PubMed:8861213}. | |
| Similarity: | Belongs to the Sif family. {ECO:0000305}. | |
