CC   -!- FUNCTION: Positive regulator of sigma-B activity. Non-phosphorylated
CC       RsbV binds to RsbW, preventing its association with sigma-B. When
CC       phosphorylated, releases RsbW, which is then free to complex with and
CC       inactivate sigma-B (By similarity). {ECO:0000250}.
CC   -!- PTM: Phosphorylated by RsbW on a serine residue. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the anti-sigma-factor antagonist family.
CC       {ECO:0000305}.
