Gallery: Stat3α Antibody #8719
Stat3α Antibody recognizes endogenous levels of total Stat3α protein. This antibody does not cross-react with Stat3β.Species predicted to react based on 100% sequence homology: Dog
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly738 of human Stat3 protein. Antibodies are purified by protein A and peptide affinity chromatography.
The Stat3 transcription factor is an important signaling molecule for many cytokines and growth factor receptors (1) and is required for murine fetal development (2). Research studies have shown that Stat3 is constitutively activated in a number of human tumors (3,4) and possesses oncogenic potential (5) and anti-apoptotic activities (3). Stat3 is activated by phosphorylation at Tyr705, which induces dimerization, nuclear translocation, and DNA binding (6,7). Transcriptional activation seems to be regulated by phosphorylation at Ser727 through the MAPK or mTOR pathways (8,9). Stat3 isoform expression appears to reflect biological function as the relative expression levels of Stat3α (86 kDa) and Stat3β (79 kDa) depend on cell type, ligand exposure, or cell maturation stage (10). It is notable that Stat3β lacks the serine phosphorylation site within the carboxy-terminal transcriptional activation domain (8).
