Recombinant Human STAT3 Protein (GST Tag)

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.

Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80°C. Reconstituted protein solution can be stored at 4-8°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
