STAT1 antibody (pSer727)

Catalog No. ABIN196892

Product Details anti-STAT1 Antibody

Target: STAT1 (Signal Transducer and Activator of Transcription 1, 91kDa (STAT1))

Binding Specificity: pSer727

Reactivity: Human, Mouse, Rat

Host: Rabbit

Clonality: Polyclonal

Conjugate: This STAT1 antibody is un-conjugated

Application: Western Blotting (WB), Immunohistochemistry (Paraffin-embedded Sections) (IHC (p)), Immunofluorescence (IF)

Specificity: This antibody detects endogenous levels of STAT1 only when phosphorylated at Serine 727.

Purification: Immunoaffinity Chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatography using non-phosphopeptide corresponding to the phosphorylation site.

Immunogen: The antiserum was produced against synthesized phosphopeptide derived from human STAT1 around the phosphorylation site of serine 727 (P-M-Sp-P-E).

Target Details for STAT1

Target: STAT1 (Signal Transducer and Activator of Transcription 1, 91kDa (STAT1))

Alternative Name: STAT1 (STAT1 Products)

Background: Signal transducer and activator of transcription that mediates signaling by interferons (IFNs). Following type I IFN (IFN-a and IFN-beta) binding to cell surface receptors, Jak kinases (TYK2 and JAK1) are activated, leading to tyrosine phosphorylation of STAT1 and STAT2. The phosphorylated STATs dimerize, 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 interferon stimulated genes, 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.Synonyms: Signal transducer and activator of transcription 1-alpha/beta, Transcription factor ISGF-3 components p91/p84
