Applications
Show applications key
Our Abpromise guarantee covers the use of ab31371 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
IHC-P: 1/50 - 1/100.
WB: 1/500 - 1/1000. Detects a band of approximately 88 kDa (predicted molecular weight: 88 kDa).
ELISA
ELISA: 1/10000.ELISA: 1/10000.
Target
Function
Transcription factor that binds to the interleukin-6 (IL-6)-responsive elements identified in the promoters of various acute-phase protein genes. Activated by IL31 through IL31RA.
Tissue specificity
Heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas.
Involvement in disease
Defects in STAT3 are the cause of hyperimmunoglobulin E recurrent infection syndrome autosomal dominant (AD-HIES) [MIM:147060]; also known as hyper-IgE syndrome or Job syndrome. AD-HIES is a rare disorder of immunity and connective tissue characterized by immunodeficiency, chronic eczema, recurrent Staphylococcal infections, increased serum IgE, eosinophilia, distinctive coarse facial appearance, abnormal dentition, hyperextensibility of the joints, and bone fractures.
Sequence similarities
Belongs to the transcription factor STAT family.
Contains 1 SH2 domain.
Post-translational
modifications
Tyrosine phosphorylated upon stimulation with EGF (By similarity). Tyrosine phosphorylated in response to IL-6, IL-11, CNTF, LIF, CSF-1, EGF, PDGF, IFN-alpha and OSM. 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.
Cellular localization
Cytoplasm. Nucleus. Shuttles between the nucleus and the cytoplasm. 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.
