細(xì)胞定位 |
Antigen Cellular Localization:
Cytoplasm. Nucleus. Note=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

功能 |
Signal transducer and transcription activator that mediates cellular responses to interleukins, KITLG/SCF and other growth factors. 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. Cytoplasmic STAT3 represses macroautophagy by inhibiting EIF2AK2/PKR activity. Plays an important role in host defense in methicillin-resistant S.aureus lung infection by regulating the expression of the antimicrobial lectin REG3G (By similarity).

總結(jié) |
The protein encoded by this gene is a member of the STATprotein family. In response to cytokines and growth factors, STATfamily members are phosphorylated by the receptor associatedkinases, and then form homo- or heterodimers that translocate tothe cell nucleus where they act as transcription activators. Thisprotein is activated through phosphorylation in response to variouscytokines and growth factors including IFNs, EGF, IL5, IL6, HGF,LIF and BMP2. This protein mediates the expression of a variety ofgenes in response to cell stimuli, and thus plays a key role inmany cellular processes such as cell growth and apoptosis. Thesmall GTPase Rac1 has been shown to bind and regulate the activityof this protein. PIAS3 protein is a specific inhibitor of thisprotein. Three alternatively spliced transcript variants encodingdistinct isoforms have been described.

圖像 |
STAT3 Antibody (pS727) (Cat. APR11199G) western blot analysis in Daudi cell line lysates (35ug/lane).This demonstrates the STAT3 antibody detected the STAT3 protein (arrow). Fluorescent confocal image of SY5Y cells stained with STAT3 (C-term S727) antibody. SY5Y cells were fixed with 4% PFA (20 min), permeabilized with Triton X-100 (0.2%, 30 min). Cells were then incubated with APR11199G STAT3 (C-term S727) primary antibody (1:200, 2 h at room temperature). For secondary antibody, Alexa Fluor? 488 conjugated donkey anti-rabbit antibody (green) was used (1:1000, 1h). Nuclei were counterstained with Hoechst 33342 (blue) (10 μg/ml, 5 min). Note the highly specific localization of the STAT3 mainly to the nucleus, supported by Human Protein Atlas Data (http://www.proteinatlas.org/ENSG00000168610). |
