NFE2L2 is stabilized and translocates to the nucleus, where it dimerizes with sMAF proteins. This complex binds to AREs to mediate the transcription of genes involved in iron metabolism, GSH metabolism, and ROS detoxification. SLC40A1 is a target gene of NFE2L2, with a putative ARE identified approximately -7 kb upstream of the SLC40A1 core promoter.

Phosphorylation of Oct4 increased its stability and facilitated its nuclear localization and its interaction with Sox2, which promoted the transcription of the core stemness genes POU5F1 and NANOG.

Smad6 mediates Tbx6 ubiquitination and proteasomal degradation. Tbx6 forms a ternary complex with Smad6 and Smurf1. Here, we report that Tbx6 interacts directly with Smad6, an inhibitory Smad that antagonizes the BMP signal. This interaction is mediated through the Mad homology 2 (MH2) domain of Smad6 and residues 90-180 of Tbx6. We demonstrate that Smad6 facilitates the degradation of Tbx6 protein through recruitment of Smurf1, a ubiquitin E3 ligase.

ROC analysis gives AUC = 0.78 (Figure S4A) when considering high-confidence known coupling data and suggested a threshold of LogRAi ≥ -1.0 for defining true couplings. | The score associated to this interaction has a LogRAi ≥ -1.0.

Here we report that Klf8 is repressed by Klf3 in vivo and is up-regulated by Klf1. Transcript analysis indicates that Klf8 has two promoters, both containing multiple CACCC elements. Transactivation assays and chromatin immunoprecipitation experiments indicate that Klf3 represses Klf8 directly and that Klf1 activates Klf8 directly.

CK2 physiologically phosphorylates IP6K2 at amino acid residues S347 and S356 contained within a PEST sequence, a consensus site for ubiquitination. HCT116 cells depleted of IP6K2 are resistant to cell death elicited by CK2 inhibitors. CK2 phosphorylation at the degradation motif of IP6K2 enhances its ubiquitination and subsequent degradation.

CaMKIV Phosphorylates Nova-2 and Regulates Its Nuclear Localization. CaMKIV Phosphorylates Nova-2 and Regulates Its Nuclear Localization. Conversely, Nova-2 with single or double mutations to alanine (2A and 1A2A) was predominantly nuclear, like the WT (Figures 5H and ​and5I).5I). In contrast, glutamate mutations at site 3 had no effect on Nova-2 localization (Figures 5H and ​and5I)5I) or on Nova-2 binding to RNA (Figure S5E). These results showed that active CaMKIV reduces Nova-2 nuclear localization by phosphorylating sites 1 and 2 (S25, T27).

This protein has now been shown to be phosphorylated specifically on thr(90) by several cdks, including cdc2, in vitro. Phosphorylation of prx i on thr(90) reduced the peroxidase activity of this protein by 80%.Prx i was also phosphorylated, with an efficiency similar to that observed with cdc2, when incubated in vitro with cdk2, cdk4, or cdk6 that had been immunoprecipitated from hela cell lysates with specific antibodies (data not shown).

These results suggest the important role of 14-3-3 in the dynamic regulation of NF-L assembly, and in the capacity to prevent the formation of NF-L aggregates. all seven isoforms specifically interacted with NF-L, but not NF-M or NF-H. specific interaction of 14-3-3 proteins with phosphorylated NF-L subunits also indicated the role of 14-3-3 and NF-L phosphorylation in the disassembly of neurofilaments. What is more, binding of 14-3-3 to phosphorylated NF-L subunits may prevent the dephosphorylation of these subunits by phosphatases, maintaining the hyperphosphorylation state of the subunits, which facilitates the disassembly of neurofilaments.
