ターゲット情報

  • 機能Signal transducer and transcription activator that mediates cellular responses to interleukins, KITLG/SCF, LEP and other growth factors. Once activated, recruits coactivators, such as NCOA1 or MED1, to the promoter region of the target gene (PubMed:17344214). May mediate cellular responses to activated FGFR1, FGFR2, FGFR3 and FGFR4. Binds to the interleukin-6 (IL-6)-responsive elements identified in the promoters of various acute-phase protein genes. Activated by IL31 through IL31RA. Involved in cell cycle regulation by inducing the expression of key genes for the progression from G1 to S phase, such as CCND1 (PubMed:17344214). Mediates the effects of LEP on melanocortin production, body energy homeostasis and lactation (By similarity). May play an apoptotic role by transctivating BIRC5 expression under LEP activation (PubMed:18242580). Cytoplasmic STAT3 represses macroautophagy by inhibiting EIF2AK2/PKR activity.
  • 組織特異性Heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas.
  • 関連疾患Hyperimmunoglobulin E recurrent infection syndrome, autosomal dominant
    Autoimmune disease, multisystem, infantile-onset
  • 配列類似性Belongs to the transcription factor STAT family.
    Contains 1 SH2 domain.
  • 翻訳後修飾Tyrosine phosphorylated upon stimulation with EGF. Tyrosine phosphorylated in response to constitutively activated FGFR1, FGFR2, FGFR3 and FGFR4 (By similarity). Activated through tyrosine phosphorylation by BMX. Tyrosine phosphorylated in response to IL6, IL11, LIF, CNTF, KITLG/SCF, CSF1, EGF, PDGF, IFN-alpha, LEP and OSM. Activated KIT promotes phosphorylation on tyrosine residues and subsequent translocation to the nucleus. Phosphorylated on serine upon DNA damage, probably by ATM or ATR. Serine phosphorylation is important for the formation of stable DNA-binding STAT3 homodimers and maximal transcriptional activity. ARL2BP may participate in keeping the phosphorylated state of STAT3 within the nucleus. Upon LPS challenge, phosphorylated within the nucleus by IRAK1. Upon erythropoietin treatment, phosphorylated on Ser-727 by RPS6KA5. Phosphorylation at Tyr-705 by PTK6 or FER leads to an increase of its transcriptional activity. Dephosphorylation on tyrosine residues by PTPN2 negatively regulates IL6/interleukin-6 signaling.
  • 細胞内局在Cytoplasm. Nucleus. Shuttles between the nucleus and the cytoplasm. Translocated into the nucleus upon tyrosine phosphorylation and dimerization, in response to signaling by activated FGFR1, FGFR2, FGFR3 or FGFR4. Constitutive nuclear presence is independent of tyrosine phosphorylation. Predominantly present in the cytoplasm without stimuli. Upon leukemia inhibitory factor (LIF) stimulation, accumulates in the nucleus. The complex composed of BART and ARL2 plays an important role in the nuclear translocation and retention of STAT3. Identified in a complex with LYN and PAG1.

Anti-STAT3 antibody 画像

  • ab5073 (4µg/ml) staining of paraffin embedded Mouse Thymus shows preferential staining of the medula over the cortex. Steamed antigen retrieval with Tris/EDTA buffer pH 9, HRP-staining.

  • Immunofluorescence detection using Goat polyclonal to STAT3 (ab5073) on rat (mixed neuron/glia) cell culture. Cells were fixed with paraformaldehyde, no antigen retrieval step was necessary. Primary antibody ab5073 was incubated for 1hr at room temperature (25 µg/ml). The confocal image shows anti-STAT3 positive immunoreactivity (red) in glial processes and nuclei. Blue nuclear counterstain is shown. Secondary antibody was donkey anti-goat IgG Alex fluor 568 (1/800) ab175474).

  • Immunofluorescence detection of STAT3 using Goat polyclonal to STAT3 (ab5073) on human HEK cell culture. 5% BSA was used as a blocking agent for 40 mins. Cells were fixed with methanol; no antigen retrieval step was necessary. Primary antibody ab5073 was incubated for 12 hour at RT (1/100). The confocal image shows anti-STAT3 cytosolic and plasma membrane localisation as expected.
