CC -!- FUNCTION: Signal transducer and transcription activator that mediates
CC cellular responses to interferons (IFNs), cytokine KITLG/SCF and other
CC cytokines and other growth factors. Following type I IFN (IFN-alpha and
CC IFN-beta) binding to cell surface receptors, signaling via protein
CC kinases leads to activation of Jak kinases (TYK2 and JAK1) and to
CC tyrosine phosphorylation of STAT1 and STAT2. The phosphorylated STATs
CC dimerize and associate with ISGF3G/IRF-9 to form a complex termed ISGF3
CC transcription factor, that enters the nucleus. ISGF3 binds to the IFN
CC stimulated response element (ISRE) to activate the transcription of
CC IFN-stimulated genes (ISG), which drive the cell in an antiviral state.
CC In response to type II IFN (IFN-gamma), STAT1 is tyrosine- and serine-
CC phosphorylated. It then forms a homodimer termed IFN-gamma-activated
CC factor (GAF), migrates into the nucleus and binds to the IFN gamma
CC activated sequence (GAS) to drive the expression of the target genes,
CC inducing a cellular antiviral state. Becomes activated in response to
CC KITLG/SCF and KIT signaling. May mediate cellular responses to
CC activated FGFR1, FGFR2, FGFR3 and FGFR4. Involved in food tolerance in
CC small intestine: associates with the Gasdermin-D, p13 cleavage product
CC (13 kDa GSDMD) and promotes transcription of CIITA, inducing type 1
CC regulatory T (Tr1) cells in upper small intestine.
CC {ECO:0000250|UniProtKB:P42224, ECO:0000250|UniProtKB:P42225}.
CC -!- SUBUNIT: Homodimerizes upon IFN-gamma induced phosphorylation.
CC Heterodimer with STAT2 upon IFN-alpha/beta induced phosphorylation. The
CC heterodimer STAT1:STAT2 forms the interferon-stimulated gene factor 3
CC complex (ISGF3) with IRF9. Interacts (phosphorylated at Ser-727) with
CC PIAS1; the interaction results in release of STAT1 from its target
CC gene. Interacts with IFNAR1. Interacts with IFNAR2. Found in a complex
CC with NMI and CREBBP/CBP. Interacts with NMI which is required for
CC CREBBP/CBP recruitment to the complex. Interacts with PTK2/FAK1.
CC Interacts with SRC. Interacts with ERBB4 (phosphorylated). Interacts
CC with PARP9 and DTX3L independently of IFN-beta or IFN-gamma-mediated
CC STAT1 'Tyr-701' phosphorylation. Interacts with histone
CC acetyltransferase EP300/p300 in response to INF-gamma stimulation.
CC Interacts with OTOP1. Interacts with IFNGR1 (By similarity). Interacts
CC with STAT4 (By similarity). {ECO:0000250|UniProtKB:P42224,
CC ECO:0000250|UniProtKB:P42225}.
CC -!- SUBUNIT: (Microbial infection) Interacts with African swine fever virus
CC (ASFV) MGF360-9L; this interaction mediates degradation of STAT1
CC through apoptosis. {ECO:0000269|PubMed:35076286}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:35076286}. Nucleus
CC {ECO:0000269|PubMed:35076286}. Note=Translocated into the nucleus upon
CC tyrosine phosphorylation and dimerization, in response to IFN-gamma and
CC signaling by activated FGFR1, FGFR2, FGFR3 or FGFR4. Monomethylation at
CC Lys-525 is required for phosphorylation at Tyr-701 and translocation
CC into the nucleus. Translocates into the nucleus in response to
CC interferon-beta stimulation. {ECO:0000250|UniProtKB:P42224}.
CC -!- PTM: Phosphorylated on tyrosine and serine residues in response to a
CC variety of cytokines/growth hormones including IFN-alpha, IFN-gamma,
CC PDGF and EGF. Activated KIT promotes phosphorylation on tyrosine
CC residues and subsequent translocation to the nucleus. Upon EGF
CC stimulation, phosphorylation on Tyr-701 (lacking in beta form) by JAK1,
CC JAK2 or TYK2 promotes dimerization and subsequent translocation to the
CC nucleus. Growth hormone (GH) activates STAT1 signaling only via JAK2.
CC Tyrosine phosphorylated in response to constitutively activated FGFR1,
CC FGFR2, FGFR3 and FGFR4. Phosphorylation on Ser-727 by several kinases
CC including MAPK14, ERK1/2 and CAMK2/CAMKII in response to IFN-gamma
CC stimulation, is required for maximal transcriptional activity.
CC Phosphorylated on Ser-727 by CAMK2/CAMKII in response to IFN-gamma
CC stimulation and calcium mobilization, promoting activity.
CC Phosphorylated by CAMK2/CAMKII in response to IFN-beta stimulation and
CC calcium mobilization in epithelial cells, promoting activity.
CC Phosphorylation on Ser-727 promotes sumoylation though increasing
CC interaction with PIAS. Phosphorylation on Ser-727 by PRKCD induces
CC apoptosis in response to DNA-damaging agents. Phosphorylated on
CC tyrosine residues when PTK2/FAK1 is activated; most likely this is
CC catalyzed by a SRC family kinase. Dephosphorylation on tyrosine
CC residues by PTPN2 negatively regulates interferon-mediated signaling.
CC Upon viral infection or IFN induction, phosphorylation on Ser-708
CC occurs much later than phosphorylation on Tyr-701 and is required for
CC the binding of ISGF3 on the ISREs of a subset of IFN-stimulated genes
CC IKBKE-dependent. Phosphorylation at Tyr-701 and Ser-708 are mutually
CC exclusive, phosphorylation at Ser-708 requires previous
CC dephosphorylation of Tyr-701. {ECO:0000250|UniProtKB:P42224}.
CC -!- PTM: Sumoylated with SUMO1, SUMO2 and SUMO3. Sumoylation is enhanced by
CC IFN-gamma-induced phosphorylation on Ser-727, and by interaction with
CC PIAS proteins. Enhances the transactivation activity.
CC {ECO:0000250|UniProtKB:P42224}.
CC -!- PTM: ISGylated. {ECO:0000250|UniProtKB:P42224}.
CC -!- PTM: Mono-ADP-ribosylated at Glu-657 and Glu-705 by PARP14; ADP-
CC ribosylation prevents phosphorylation at Tyr-701. However, the role of
CC ADP-ribosylation in the prevention of phosphorylation has been called
CC into question and the lack of phosphorylation may be due to sumoylation
CC of Lys-703. {ECO:0000250|UniProtKB:P42224}.
CC -!- PTM: Monomethylated at Lys-525 by SETD2; monomethylation is necessary
CC for phosphorylation at Tyr-701, translocation into the nucleus and
CC activation of the antiviral defense. {ECO:0000250|UniProtKB:P42224}.
CC -!- PTM: Deubiquitinated by USP13; leading to STAT1 stabilization and
CC positive regulation of type I and type II IFN signalings.
CC {ECO:0000250|UniProtKB:P42224}.
CC -!- SIMILARITY: Belongs to the transcription factor STAT family.
CC {ECO:0000305}.
CC -!- CAUTION: Has been shown to be mono-ADP-ribosylated at Glu-657 and Glu-
CC 705 by PARP14 which prevents phosphorylation at Tyr-701 (By
CC similarity). However, the role of ADP-ribosylation in the prevention of
CC phosphorylation has been called into question (By similarity). It has
CC been suggested that the lack of phosphorylation may be due to
CC sumoylation of Lys-703 (By similarity). {ECO:0000250|UniProtKB:P42224}.
