Biological background

STAT1 (protein: P2X purinoceptor 1) is a commonly studied target in molecular and cellular biology. Functional context (as provided): Signal transducer and transcription activator that mediates cellular responses to interferons (IFNs), cytokine KITLG/SCF and other cytokines and other growth factors. 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. 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. In response to type II IFN (IFN-gamma), STAT1 is tyrosine- and serine-phosphorylated. 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. Becomes activated in response to KITLG/SCF and KIT signaling. May mediate cellular responses to activated FGFR1, FGFR2, FGFR3 and FGFR4. . Reported cellular localization context: Cytoplasm . Nucleus . Translocated into the nucleus upon tyrosine phosphorylation and dimerization, in response to IFN-gamma and signaling by activated FGFR1, FGFR2, FGFR3 or FGFR4. Tissue expression notes (as provided): Brain. Highly expressed in hippocampus, amygdala, cerebral cortex and cerebellum. Also expressed in heart, lung, skeletal muscle, testis, prostate and placenta. .

Research relevance and current trends

• Research context keywords from the source record include: Cancer,Epigenetics and Nuclear Signaling,Nuclear Signaling,Nuclear Signaling Pathways,Signal Transduction,Signaling Pathway,Transcription.
• Current studies often focus on connecting target abundance/localization to pathway perturbations across models, tissues, and cell states.
• Quantitative and multiplexed assays (e.g., imaging + immunoblot panels) are commonly used to compare phenotypes across conditions and time-courses.

Common research applications

• Western blotting (WB): assess relative target abundance across samples, treatments, or time-points.
• Immunohistochemistry (IHC): evaluate spatial distribution of target-positive staining in tissue architecture.
• Immunofluorescence/ICC (IF/ICC): visualize subcellular localization patterns and cell-to-cell heterogeneity.
• Flow cytometry: quantify target-positive populations and compare shifts in marker distributions.
• Immunoprecipitation (IP): enrich target complexes for downstream immunoblot or interaction analyses.

Workflow ideas (metafield): Validate STAT1 antibody specificity using KO/KD control samples (WB/IF/IHC as appropriate), Detect STAT1 expression by Western blot in cell or tissue lysates, Detect STAT1 in FFPE tissue sections by immunohistochemistry, Localize STAT1 by immunofluorescence/immunocytochemistry in cultured cells, Quantify STAT1-positive cells by flow cytometry in single-cell suspensions, Enrich STAT1 by immunoprecipitation from lysates for downstream analysis

Notes for experimental interpretation

• Consider isoforms and post-translational modifications (PTMs) that may shift apparent molecular weight or epitope accessibility.
• Apparent molecular weight may vary by sample type and processing (observed MW: 110 kDa; calculated MW: 87335 MW).
• Control concepts: include appropriate negative controls (e.g., isotype, KO/KD samples) and orthogonal validation when feasible.
