    Background
    Function: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:15653507, PubMed:16285960, PubMed:17344214, PubMed:18242580, PubMed:18782771, PubMed:22306293, PubMed:23084476, PubMed:28262505, PubMed:32929201, PubMed:38404237). Once activated, recruits coactivators, such as NCOA1 or MED1, to the promoter region of the target gene (PubMed:15653507, PubMed:16285960, PubMed:17344214, PubMed:18782771, PubMed:28262505, PubMed:32929201). May mediate cellular responses to activated FGFR1, FGFR2, FGFR3 and FGFR4 (PubMed:12873986). Upon activation of IL6ST/gp130 signaling by interleukin-6 (IL6), binds to the IL6-responsive elements identified in the promoters of various acute-phase protein genes (PubMed:12359225). Activated by IL31 tH2O2gh 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): acetylation promotes its transcription activity and cell differentiation while deacetylation and oxidation of lysine residues by LOXL3 inhibits differentiation (PubMed:28065600, PubMed:28262505). 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). 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 (By similarity)

    Subunit:Forms a homodimer or a heterodimer with a related family member (at least STAT1) (PubMed:15653507, PubMed:28065600). Component of a promoter-binding complex composed of STAT3, NFATC3 and NFATC4; complex formation is enhanced by calcineurin (By similarity). Interacts with IL31RA, NCOA1, PELP1, SIPAR, SOCS7, STATIP1 and TMF1 (By similarity) (PubMed:15194700, PubMed:15467733, PubMed:15677474, PubMed:15994929, PubMed:17344214). Interacts with IL23R in presence of IL23 (PubMed:12023369). Interacts (via SH2 domain) with NLK. Interacts with ARL2BP; the interaction is enhanced by LIF and JAK1 expression (By similarity). Interacts with KPNA4 and KPNA5; KPNA4 may be the primary mediator of nuclear import (By similarity). Interacts with CAV2; the interaction is increased on insulin-induced tyrosine phosphorylation of CAV2 and leads to STAT3 activation (By similarity). Interacts with ARL2BP; interaction is enhanced with ARL2 (PubMed:18234692). Interacts with NEK6 (By similarity). Binds to CDK9 when activated and nuclear (PubMed:17956865). Interacts with BMX (PubMed:10688651). Interacts with ZIPK/DAPK3 (PubMed:16219639). Interacts with PIAS3; the interaction occurs on stimulation by IL6, CNTF or OSM and inhibits the DNA binding activity of STAT3 (PubMed:9388184). In prostate cancer cells, interacts with PRKCE and promotes DNA binding activity of STAT3 (PubMed:17875724). Interacts with STMN3, antagonizing its microtubule-destabilizing activity (By similarity). Interacts with the 'Lys-129' acetylated form of BIRC5/survivin (PubMed:20826784). Interacts with FER (PubMed:19147545). Interacts (via SH2 domain) with EIF2AK2/PKR (via the kinase catalytic domain) (PubMed:23084476). Interacts with INPP5F; the interaction is independent of STAT3 Tyr-705 phosphorylation status (PubMed:25476455). Interacts with FGFR4 (PubMed:26675719). Interacts witH2O2IAD1 (By similarity). Interacts witH2O2IAD2 (PubMed:29743632). Interacts (unphosphorylated or phosphorylated at Ser-727) with PHB1 (PubMed:31899195). Interacts and may form heterodimers with NHLH1 (By similarity). Found in a complex with SLC39A6, SLC39A10 and with the 'Ser-727' phosphorylated form of STAT3 tH2O2ghout mitosis (PubMed:32797246). Interacts (when phosphorylated at Tyr-705) with CD274/PD-L1; promoting nuclear translocation of CD274/PD-L1 (PubMed:32929201). Interacts (when acetylated) with EP300 (via bromo domain); interaction takes place following STAT3 acetylation by EP300 and promotes enhanceosome assembly (PubMed:18782771). Interacts (when acetylated) with BRD2 (via bromo domain); interaction promotes STAT3 recruitment to cH2O2atin and T-helper Th17 cell differentiation (PubMed:28262505). Interacts with FAM220A/SIPAR; the interaction occurs in both the nucleus and the cytoplasm, is enhanced by IL6 and promotes STAT3 dephosphorylation (By similarity). Interacts in both unphosphorylated and phosphorylated forms with FAM220A but interacts preferentially in the phosphorylated form in the nucleus (By similarity). Interacts with PTPN2; the interaction is promoted by FAM220A and leads to STAT3 dephosphorylation which negatively regulates STAT3 transcriptional activator activity (By similarity)

    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
