CC   -!- FUNCTION: Together with YxlE, is important for negative regulation of
CC       sigma Y activity, being the major negative regulator.
CC       {ECO:0000269|PubMed:12897008}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000305}.
CC   -!- INDUCTION: Expression is sigma Y-dependent. Induced upon nitrogen
CC       starvation. {ECO:0000269|PubMed:14769884}.
