Stat3 serine 727 phosphorylation
WebHowever, the essential role in this process is given just by the STAT3 phosphorylation at serine 727 . In recent years, there has been an increasing interest in deciphering the mechanisms responsible for the regulation of ESC pluripotency and differentiation, especially due to the possible use of stem cells in the therapy [ 13 , 14 , 15 ]. WebOct 30, 2006 · Here we show that for Stat3, one of the two conserved prolines (P728) is important for S727 phosphorylation while L724 and M726 are not required ( Figs. 1 B and 4 A). In contrast, for IFN-γ-induced Stat1S727 phosphorylation by CaMKII, the conserved L724 is necessary [16].

WebSTAT3 has been identified as a therapeutic target in glioma because of its involvement in mechanisms sustaining tumor escape to both standard treatment and immune control. Here, we studied the role of STAT3 activation on tyrosine 705 (Y705) and serine 727 (S727) in glioma radioresistance. This study explored STAT3 phosphorylation on Y705 ... WebJun 12, 2014 · In circulating CLL cells, the signal transducer and activator of transcription 3 (STAT3) is constitutively phosphorylated on serine-727 residues. 6, 7 Tyrosine phosphorylated (p) STAT3 is rarely detected in unstimulated circulating CLL cells in PB.
WebSep 15, 1998 · The role of serine-727 phosphorylation in regulating tyrosine phosphorylation of Stat3 in our system was addressed directly by using the Stat3S727A mutant that abolishes serine phosphorylation at this site; this is the same mutation studied in ref. 31. WebSep 22, 2016 · Activation of STAT3 by phosphorylation on Y705 and S727 in non-neoplastic cell contributes to their transformation. pSTAT3-Y705 and pSTAT3-S727 are involved in stem cell proliferation and survival.
