UniProtKB description: Component of the Dot/Icm type IVB secretion system (T4BSS), which is used to inject bacterial effector proteins into eukaryotic host cells (PubMed:15661013, PubMed:18069892, PubMed:17040490, PubMed:22694730, PubMed:32513920). Part of a subcomplex which recruits effector proteins and delivers them to the core transmembrane subcomplex (PubMed:23028312, PubMed:32513920). The IcmS/IcmW protein complex plays an important role in protein translocation by interacting with multiple Dot/Icm effector proteins to facilitate their translocation into host cells (PubMed:15661013, PubMed:18069892). Interaction promotes conformational changes in the effector protein, which may facilitate display of a C-terminal translocation signal (PubMed:18069892). May maintain the substrates in a translocation competent form (PubMed:23028312). Required for intracellular growth in host cells, replicative phagosome formation and phagosome trafficking (PubMed:10361301, PubMed:11115108).
