ChIP - Anti-STAT3 Antibody (AB327249)

ChIP-Exo-Seq composite graph for ab327249 tested in K562 cells at 1–10 µg per reaction. Strand-specific reads (blue : forward, red : reverse) and IgG controls (black : forward, grey : reverse) are plotted against the distance from a composite set of reference binding sites. The antibody exhibits robust target enrichment compared to a non-specific IgG control and precisely reveals its structural organization around the binding site. Data generated by Prof. B. F. Pugh´s Lab at Cornell University.

Target data

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 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) : 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).
