Supplementary information

Signal Transducer and Activator of Transcription 1 (STAT1) is a protein of about 91 kDa commonly known simply as STAT1. It belongs to the STAT protein family which is involved in gene regulation. STAT1 expresses widely in many tissues including the immune system where it plays a major role. As an important player in cellular responses to cytokines and growth factors STAT1 becomes activated through phosphorylation often referred to as phospho-STAT1. This phosphorylation promotes dimerization an important step for its function.
Biological function summary

The STAT1 protein influences cell survival and immune responses. It functions as a transcription factor and participates in the interferon signaling pathway. In this setting it forms a complex with other STAT proteins such as STAT2 and STAT3 to regulate gene expression. By binding to specific DNA sequences in the nucleus STAT1 alters transcription in response to extracellular signals. It contributes to antiviral defense mechanisms and antiproliferative activities in various cells.

Pathways

The STAT1 protein plays essential roles in the JAK-STAT signaling pathway and interferon signaling pathway. It operates closely with proteins such as JAK1 and TYK2 which are involved in the phosphorylation process activating STAT1. During this activation STAT1 helps initiate cellular responses to interferons a type of signaling protein released during viral infections. The JAK-STAT pathway facilitates various physiological processes including immune responses and cell growth regulation.

STAT1 dysregulation often connects to autoimmune diseases and infectious diseases. Elevated STAT1 activity associates with disorders like systemic lupus erythematosus where an imbalanced immune response occurs. Phosphorylation of STAT1 can also relate to chronic infections in cases where proper immune response activation becomes impaired. In certain cancers STAT1 interaction with proteins like SOCS1 might contribute to tumor immune evasion highlighting its vital role in pathology.

Target data

Signal transducer and transcription activator that mediates cellular responses to interferons (IFNs), cytokine KITLG/SCF and other cytokines and other growth factors (PubMed : 12764129, PubMed : 12855578, PubMed : 15322115, PubMed : 23940278, PubMed : 34508746, PubMed : 35568036, PubMed : 9724754). Following type I IFN (IFN-alpha and IFN-beta) binding to cell surface receptors, signaling via protein kinases leads to activation of Jak kinases (TYK2 and JAK1) and to tyrosine phosphorylation of STAT1 and STAT2. The phosphorylated STATs dimerize and associate with ISGF3G/IRF-9 to form a complex termed ISGF3 transcription factor, that enters the nucleus (PubMed : 28753426, PubMed : 35568036). ISGF3 binds to the IFN stimulated response element (ISRE) to activate the transcription of IFN-stimulated genes (ISG), which drive the cell in an antiviral state (PubMed : 28753426, PubMed : 35568036). In response to type II IFN (IFN-gamma), STAT1 is tyrosine- and serine-phosphorylated (PubMed : 26479788). It then forms a homodimer termed IFN-gamma-activated factor (GAF), migrates into the nucleus and binds to the IFN gamma activated sequence (GAS) to drive the expression of the target genes, inducing a cellular antiviral state (PubMed : 8156998). Becomes activated in response to KITLG/SCF and KIT signaling (PubMed : 15526160). May mediate cellular responses to activated FGFR1, FGFR2, FGFR3 and FGFR4 (PubMed : 19088846). Following bacterial lipopolysaccharide (LPS)-induced TLR4 endocytosis, phosphorylated at Thr-749 by IKBKB which promotes binding of STAT1 to the 5'-TTTGAGGC-3' sequence in the ARID5A promoter, resulting in transcriptional activation of ARID5A and subsequent ARID5A-mediated stabilization of IL6 (PubMed : 32209697). Phosphorylation at Thr-749 also promotes binding of STAT1 to the 5'-TTTGAGTC-3' sequence in the IL12B promoter and activation of IL12B transcription (PubMed : 32209697). Involved in food tolerance in small intestine : associates with the Gasdermin-D, p13 cleavage product (13 kDa GSDMD) and promotes transcription of CIITA, inducing type 1 regulatory T (Tr1) cells in upper small intestine (By similarity).
