CC   -!- FUNCTION: Involved in the regulation of nitrogen metabolism (By
CC       similarity). Regulates the activity of its targets by protein-protein
CC       interaction in response to the nitrogen status of the cell (By
CC       similarity). Regulates the activity of the ammonia channel Amt2 via
CC       direct interaction (By similarity). {ECO:0000250|UniProtKB:Q60381}.
CC   -!- SUBUNIT: Homotrimer (By similarity). Interacts and forms a complex with
CC       Amt2 (By similarity). {ECO:0000250|UniProtKB:Q60381}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:B8ZYW0}.
CC   -!- SIMILARITY: Belongs to the P(II) protein family. {ECO:0000255|PROSITE-
CC       ProRule:PRU00675}.
