The cytoplasmic domain is able to inactivate SigW and the extracellular and transmembrane domains are crucial for sensing and transducing the signal that triggers SigW activation (PubMed:15130127). The N-terminus binds the zinc ion and is followed by a long helix (about residues 40-80) that fits into a hydrophobic surface groove on SigW, probably blocking its ability to interact with the -10 and -35 promoter elements (PubMed:28319136).
