for Recombinant STAT3 proteinBackground

STAT3 (Signal Transducer And Activator Of Transcription 3), also known as APRF (Acute-Phase Response Factor) or ADMIO, HIES, is a signal transducer and transcription activator that mediates cellular responses to interleukins, KITLG/SCF, LEP and other growth factors. Once activated, STAT3 can recruit coactivators, such as NCOA1 or MED1, to the promoter region of the target gene. Deacetylation and oxidation of lysine residues by LOXL3, leads to disrupt STAT3 dimerization and inhibit its transcription activity. STAT3 can bind to the interleukin-6 (IL-6)-responsive elements identified in the promoters of various acute-phase protein genes. It also acts as a regulator of inflammatory response by regulating differentiation of naive CD4(+) T-cells into T-helper Th17 or regulatory T-cells. It is involved in cell cycle regulation by inducing the expression of key genes for the progression from G1 to S phase, such as CCND1. Cytoplasmic STAT3 represses macroautophagy by inhibiting EIF2AK2/PKR activity.
