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 . May mediate cellular responses to activated FGFR1, FGFR2, FGFR3 and FGFR4 . Upon activation of IL6ST/gp130 signaling by interleukin-6 , binds to the IL6-responsive elements identified in the promoters of various acute-phase protein genes . Activated by IL31 through IL31RA . Acts as a regulator of inflammatory response by regulating differentiation of naive CD4 T-cells into T-helper Th17 or regulatory T-cells : acetylation promotes its transcription activity and cell differentiation while deacetylation and oxidation of lysine residues by LOXL3 inhibits differentiation . Involved in cell cycle regulation by inducing the expression of key genes for the progression from G1 to S phase, such as CCND1 . Mediates the effects of LEP on melanocortin production, body energy homeostasis and lactation . May play an apoptotic role by transctivating BIRC5 expression under LEP activation . Cytoplasmic STAT3 represses macroautophagy by inhibiting EIF2AK2/PKR activity . Plays a crucial role in basal beta cell functions, such as regulation of insulin secretion . Following JAK/STAT signaling activation and as part of a complex with NFATC3 and NFATC4, binds to the alpha-beta E4 promoter region of CRYAB and activates transcription in cardiomyocytes .
