產(chǎn)品描述：

E.coli-expressed recombinant human signal transducer and activator of transcription 3 (STAT3) contains 191 amino acids covering the partial-length of STAT3 protein (50-240aa). And it has its N-terminus fused with a 6xHis-SUMO-tag and a total molecular weight of 38.3 kDa. The purity of this human STAT3 protein is greater than 90% measured by SDS-PAGE. Its identity was validated by the LC-MS/MS analysis. This protein is in-stock, which means there is no waiting period for protein preparation. This recombinant STAT3 protein may find uses in the specific antibody synthesis or the studies of immunology.

STAT3 transduces extracellular signals from cytokines such as IL6, Il8, and IL35 and regulates the expression of numerous genes crucial for immune responses and cell differentiation. STAT3 is also regarded as an early tumor diagnostic marker and is known to promote breast cancer malignancy. JAK–STAT3 signaling is critical for cancer development in both tumor cells and the tumor microenvironment. Recent studies showed that overexpressed and constitutively activated STAT3 is involved in the proliferation, progression, metastasis, and chemoresistance of breast cancer.

靶點(diǎn)詳情

功能：

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 (IL6), 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 (Treg): deacetylation and oxidation of lysine residues by LOXL3, leads to disrupt STAT3 dimerization and inhibit its transcription activity. 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.
