pfam01584: CheW (This model is not part of the current CDD release)
CheW-like domain
CheW proteins are part of the chemotaxis signaling mechanism in bacteria. CheW interacts with the methyl accepting chemotaxis proteins (MCPs) and relays signals to CheY, which affects flageller rotation. This family includes CheW and other related proteins that are involved in chemotaxis. The CheW-like regulatory domain in CheA binds to CheW, suggesting that these domains can interact with each other.
