CC -!- FUNCTION: Transcription factor involved in the regulation of gene
CC expression in response to extracellular amino acid levels. Synthesized
CC as latent cytoplasmic precursor, which, upon a signal initiated by the
CC plasma membrane SPS (SSY1-PTR3-SSY5) amino acid sensor system, becomes
CC proteolytically activated and relocates to the nucleus, where it
CC induces the expression of SPS-sensor-regulated genes, including the
CC amino-acid permeases AGP1, BAP2, BAP3 and GNP1. Binding to promoters is
CC facilitated by DAL81. Involved in the repression of genes subject to
CC nitrogen catabolite repression and genes involved in stress response.
CC Negatively regulated by inner nuclear membrane proteins ASI1, ASI2 and
CC ASI3, which prevent unprocessed precursor forms that escape cytoplasmic
CC anchoring from inducing SPS-sensor-regulated genes. May be involved in
CC pre-tRNA splicing (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Interacts (via Region II) with SSY5; protease component of the
CC SPS-sensor.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Peripheral membrane
CC protein {ECO:0000250}; Cytoplasmic side {ECO:0000250}. Nucleus
CC {ECO:0000250}. Note=Localizes to the cytoplasm in its unprocessed form
CC and is targeted to the nucleus after proteolytic processing upon
CC induction by amino acids. The SCF(MET30) ubiquitin ligase complex
CC negatively regulates nuclear accumulation of the processed form in the
CC absence of high extracellular methionine levels (By similarity).
CC {ECO:0000250}.
CC -!- DOMAIN: The N-terminal inhibitory domain contains conserved sequence
CC elements important for cytoplasmic retention (Region I) and proteolytic
CC processing (Region II) of the protein. Region I is also required for
CC ASI1/2/3-mediated negative regulation of transcription (By similarity).
CC {ECO:0000250}.
CC -!- PTM: Phosphorylated by casein kinase I. Phosphorylation is not
CC dependent on the extracellular amino acid levels, but is a prerequisite
CC for proteolytic processing (By similarity). {ECO:0000250}.
CC -!- PTM: Activated by the amino acid-induced proteolytic removal of an N-
CC terminal inhibitory domain by serine protease SSY5, an intrinsic
CC component of the SPS-sensor. Processing requires at least 2 components
CC of the SCF(GRR1) ubiquitin ligase complex, namely the F-box protein
CC GRR1 and the E2 enzyme CDC34, but does not depend on the proteasome.
CC Processing is negatively regulated by the protein phosphatase 2A
CC regulatory subunit RTS1 (By similarity). {ECO:0000250}.
