"Moreover, SPOP specifically interacted with Nanog both in vitro and in cells ( xref – xref ) but not with other stem cell determining factors such as Oct4, Sox2, and Klf4 in cells ( xref )."

"The cancer-associated NANOG S68Y mutant is refractory for SPOP-mediated degradation since NANOG Ser68 is required for the direct interaction between SPOP and NANOG."

"Co-immunoprecipitation experiments in SW1990 cells showed that SPOP interacted with the stem-cell marker NANOG, and this interaction has recently been shown to play a critical role in regulating progression of prostate cancer."

"In addition, SPOP mediated NANOG degradation is controlled by the AMPK-BRAF signal axis through the phosphorylation of NANOG at Ser68, which blocked the interaction between SPOP and NANOG."

"However, the cancer-associated mutation 66 PDYST 70 in the NANOG mutant increased steric hindrance and impaired its interaction with SPOP ( xref ), suggesting that the cancer-associated mutant S68Y may affect the interaction between NANOG and SPOP."

"Importantly, deleting the putative motif 66PDSST 70 (ΔPDSST) impaired the interaction between Nanog and SPOP both in cells and in vitro ( xref , xref , and xref ), leading to acquired resistance to SPOP-mediated destruction ( xref – xref ) and poly-ubiquitination in cells and in vitro ( xref and xref )."

"Clinically, cancer-associated mutations in the MATH domain of SPOP disrupt the interaction between SPOP and NANOG, thereby preventing SPOP-mediated destruction of NANOG, stabilizing NANOG from AMPK-BRAF-signaling-axis-induced phosphorylation, and consequently promoting the maintenance of PCa stem-like cells."

"Notably, we observed that deletion of the MATH domain could disrupt SPOP interaction with Nanog and abrogate SPOP-mediated Nanog destruction ( xref and xref )."

"Our data indicated that SPOP specifically interacts with NANOG, but not other stem cell transcriptional factors, including OCT4, SOX2, and KLF4 ( xref )."

"SPOP-Q360* repressed levels of NANOG and other downstream proteins to a much weaker extent than SPOP-WT (Fig. 7d), and these results were associated with impaired interaction between SPOP and NANOG, as well as impaired ubiquitination of NANOG (Fig. 7e, f)."

"We next explored whether the residues located in the SBC motif involve in the interaction between NANOG and SPOP."

"In prostate cancer, tumor suppressor SPOP interacts with Nanog and promotes Nanog poly-ubiquitination and subsequent degradation, but Pin1 functions as an upstream Nanog regulator and impairs its recognition by SPOP, stabilizing Nanog to promote the cancer stem cell traits and tumor progression ( xref )."

"Notably, we found that well-characterized Pin1 inhibitors, PiB ( xref ; xref ; xref ) and Juglone ( xref ), could promote SPOP-mediated Nanog degradation ( xref and xref ) through elevating Nanog interaction with SPOP in cells ( xref and xref )."

"Furthermore, in vitro phosphorylation assay demonstrated that BRAF could phosphorylate NANOG at Ser68 and the phosphorylation of NANOG at Ser68 prevented the interaction between SPOP and NANOG in vitro ( xref - xref )."

"Our data showed that inhibition of BRAF increased the interaction between SPOP and NANOG ( xref ) and thereby promoted NANOG ubiquitination in DU145 cells ( xref )."

"Our data showed that wild-type SPOP directly interacted with NANOG whereas the absence of the MATH domain completely abrogated the binding in vitro and in vivo ( xref and xref )."

"Moreover, our data showed that NANOG specifically interacts with SPOP, but not other Cullin3-based E3 ligase adaptor proteins ( xref )."

"Taken together, these results demonstrate that BRAF directly phosphorylates NANOG at Ser68 and increases the self-renewal capacity and cell proliferation of PCa cells by impairing the interaction between SPOP and NANOG."

"In addition, SPOP-mediated NANOG degradation is controlled by the AMPK-BRAF signal axis through the phosphorylation of NANOG at Ser68, which blocked the interaction between SPOP and NANOG."

"Since BRAF can phosphorylate NANOG at Ser68, we examined whether BRAF affects the interaction between NANOG and SPOP."

"To confirm this result, we examined the interaction between NANOG S68Y and SPOP."

"Moreover, inhibition of AMPK abrogated the interaction between SPOP and NANOG, while activation of AMPK strengthened the association between SPOP and NANOG ( xref and xref )."

"Given that Pin1 recognizes the pSer/pThr-Pro motif and two SP sites (S65 and S71) located nearby the SPOP binding motif on the Nanog protein ( xref ), we speculated that Pin1 might disrupt Nanog interaction with SPOP through binding these two SP sites."

"Notably, we found that Nanog specifically interacted with SPOP, but not other Cullin 3-based E3 ligase adaptor proteins including Keap1, KLHL2, KLHL3, KLHL12, KLHL20, or COP1/ DET1, a Cullin 4-based E3 ligase substrate adaptor protein ( xref ; xref ) ( xref and xref )."

"In keeping with this notion, we found that Pin1 WT (Pin1-WT), but not its enzymatically inactive mutant W34A/K63A ( xref ), suppressed SPOP-mediated degradation of Nanog largely through disrupting the interaction between SPOP and Nanog in cells ( xref and xref )."
