Some Recent Findings
- Phosphorylation stabilizes Nanog by promoting its interaction with Pin1[2]"Here we show that Nanog, a transcription factor crucial for the self-renewal of ESCs, is phosphorylated at multiple Ser/Thr-Pro motifs. This phosphorylation promotes the interaction between Nanog and the prolyl isomerase Pin1, leading to Nanog stabilization by suppressing its ubiquitination. Inhibition of Pin1 activity or disruption of Pin1-Nanog interaction in ESCs suppresses their capability to self-renew and to form teratomas in immunodeficient mice. Therefore, in addition to the stringent transcriptional regulation of Nanog, the expression level of Nanog is also modulated by posttranslational mechanisms."
- Nanog variability and pluripotency regulation of embryonic stem cells[3]"The expression of the transcription factors Oct4, Sox2, and Nanog is commonly associated with pluripotency of mouse embryonic stem (ES) cells. However, recent observations suggest that ES cell populations are heterogeneous with respect to the expression of Nanog and that individual ES cells reversibly change their Nanog expression level."
