Functional Description From UniProt
 FUNCTION: Possible positive regulator of sigma-B activity (By similarity). Non-phosphorylated BtrV binds to BtrW, preventing its association with an unknown partner(s) that might be sigma-B. When phosphorylated, releases BtrW, which is then free to complex with and inactivate its partner. Involved in type III secretion system (TTSS)
