Anti-Stat3 (S691) Antibody

The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is > 95% (by SDS-PAGE) .

Signal transducer and transcription activator that mediates cellular responses to interleukins, KITLG/SCF, LEP and other growth factors (PubMed:10688651, PubMed:12359225, PubMed:12873986, PubMed:15194700, PubMed:17344214, PubMed:18242580, PubMed:23084476) . 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 (PubMed:12873986) . Binds to the interleukin-6 (IL-6) -responsive elements identified in the promoters of various acute-phase protein genes (PubMed:12359225) . Activated by IL31 through IL31RA (PubMed:15194700) . Acts as a regulator of inflammatory response by regulating differentiation of naive CD4 (+) T-cells into T-helper Th17 or regulatory T-cells (Treg) : deacetylation and oxidation of lysine residues by LOXL3, leads to disrupt STAT3 dimerization and inhibit its transcription activity (PubMed:28065600) . 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 (PubMed:23084476) . Plays a crucial role in basal beta cell functions, such as regulation of insulin secretion (By similarity) .
