Phosphorylation regulates human oct4
WebHuman Oct4 is known to be modified by O-GlcNAc (Webster et al. 2009), although the actual site of attachment or the functional implications of this modification have not yet been determined. In this study we showed that human Oct4 is extensively modified by O-GlcNAc which can regulate transcriptional activity of a variety of promoters. Results WebSep 5, 2014 · Critical amounts of human Oct4-IA are required to sustain stem cell self-renewal and it has been shown that Oct4-IB is not related to stemness. In humans, Oct4 …
