WebApr 2, 2012 · The mutant mimicking the constitutively phosphorylated protein exhibited greatly reduced reprogramming efficiency compared with WT OCT4. Still, the mutant was capable of producing iPS colonies, indicating that ( i ) the mutant protein was functional at some level and ( ii ) other forms of regulation are required to either completely inactivate ... WebSTAT5A-N642H was constitutively phosphorylated and activated in the absence of cytokine stimulation. The mutation of STAT5A-N642H is localized to an important residue (βD4) in the 4th β-sheet of the SH2 domain (Fig. 9), which is very close to the Tyr(P)-binding loop in the three-dimensional structure
