WebNov 27, 2024 · DNP treatment altered the phosphorylation of ezrin (threonine 567), vimentin (serine 55), stathmin (serine 25) and STAT3 (serine 727). Furthermore, it was shown that DNP-dependent metastasis is mediated in part through ezrin at threonine 567, as DNP-mediated metastasis was decreased when threonine 567 of ezrin was mutated. WebSTAT3 is a protein that plays an important role in controlling ESC fate. STAT3's activity in the cell is largely controlled by its two phosphorylation sites: tyrosine 705 and serine 727. In this study, we found that STAT3 phosphorylations at tyrosine 705 and serine 727 play distinct roles in controlling ESC fate.
