Cyclin B1/Cdk1-mediated CI phosphorylation enhances CI activity, whereas deficiency of such phosphorylation in each of the relevant CI subunits results in impairment of CI function.|These results were confirmed by generating phosphorylation defective forms of the five CI subunits through substitutions of S/T residues with Alanine (A) on either Cdk1 optimal or minimal consensus motifs (T383 on NDUFV1, S105 on NDUFV3, S364 on NDUFS2, S55/S29/T5 on NDUFB6, and T142/T120 on NDUFA12).

P07948 | Q8N6F7 | 1 | phosphorylation | up-regulates activity | 0.245 | Herein, we demonstrate phosphorylation of HGAL by Syk and Lyn kinases at tyrosines Y80, Y86, Y106Y107, Y128, and Y148. Y148 (in black) was already phosphorylated before the addition of kinases. We demonstrate that Grb2 facilitates HGAL and Syk binding following BCR stimulation but does not affect the HGAL-mediated increase in Syk kinase activity. Previous studies showed that Grb2 inhibits BCR signaling by decreasing the activation of Syk by Lyn.11 Thus, while HGAL and Grb2 oppositely affect Syk kinase activity, this is not due to direct Grb2 effects on HGAL-mediated Syk kinase activation. | SIGNOR-273560 |

ABIN1 and TAX1BP1 together disrupted the interactions between the E3 ubiquitin ligase TRAF3 and TBK1/IKKi to attenuate lysine 63-linked polyubiquitination of TBK1/IKKi. | SIGNOR-275735 |
Q9Y6K1 | P42658 | 1 | transcriptional regulation | down-regulates quantity by repression | 0.2 | In the absence of Dnmt3b, Dnmt3a was associated with Dpp6 gene promoter and regulated its expression and methylation in P19 cells. | SIGNOR-268962 |
O60664 | P20645 | 1 | relocalization | up-regulates activity | 0.73 | TIP47 is present in cytosol and on endosomes and is required for MPR transport from endosomes to the trans-Golgi network in vitro and in vivo. TIP47 recognizes a phenylalanine/tryptophan signal in the tail of the cation-dependent MPR that is essential for its proper sorting within the endosomal pathway. These data suggest that TIP47 binds MPR cytoplasmic domains and facilitates their collection into transport vesicles destined for the Golgi. | SIGNOR-253093 |
Q02790 | P68400 | 0 | phosphorylation | down-regulates activity | 0.343 | Thr-143 in the hinge I region was identified as the major phosphorylation site for CK2. | Most importantly, CK2-phosphorylated FKBP52 did not bind to HSP90 | SIGNOR-250865 |

Cats localizes to the nucleus and shows a preference for nucleoli. Expression of cats was able to markedly increase the nuclear localization of calm and of the leukemogenic fusion protein calm/af10. | SIGNOR-144680 |
P22415 | O14672 | 1 | transcriptional regulation | up-regulates quantity by expression | 0.27 | The promoter region of ADAM10 contains several transcription factor binding sites that can stimulate its transcription.

P48436 | Q05086 | 0 | ubiquitination | down-regulates quantity by destabilization | 0.261 | We show that E6-AP ubiquitinates SOX9 in vitro and in vivo and that SOX9 levels are enhanced after addition of the proteasome inhibitor bortezomib. Similar, siRNA knockdown of E6-AP and the E2 ligase Ubc9 increased cellular SOX9 amounts, supporting the notion that SOX9 may be ubiquitinated in hypertrophic chondrocytes by E6-AP and degraded by proteasomes. | SIGNOR-272134 |
Q9Y297 | P35222 | 1 | ubiquitination | down-regulates | 0.872 | Here we show that fwd1 (the mouse homologue of slimb/betatrcp), an f-box/wd40-repeat protein, specifically formed a multi-molecular complex with beta-catenin, axin, gsk-3beta and apc. Mutations at the signal-induced phosphorylation site of beta-catenin inhibited its association with fwd1. Fwd1 facilitated ubiquitination and promoted degradation of beta-catenin, resulting in reduced cytoplasmic beta-catenin levels. | SIGNOR-67374 |
Q12888 | P06493 | 0 | phosphorylation | down-regulates activity | 0.599 | Nuclear import of 53BP1 is required for proper localization of 53BP1 and maintenance of genome integrity. 53BP1 has a classical bipartite nuclear localization signal (NLS) of sequence 1666-GKRKLITSEEERSPAKRGRKS-1686. Ser1678 within the 53BP1 NLS can be phosphorylated by CDK1/cyclin B, and a phosphomimetic substitution of Ser1678 with aspartate has been shown to negatively regulate nuclear import of 53BP1. | SIGNOR-264412 |
P0DP23 | P00533 | 0 | phosphorylation | down-regulates | 0.404 | Phosphorylation of calmodulin by the epidermal-growth-factor-receptor tyrosine kinase. Phosphorylated calmodulin does not exhibit the characteristic ca2+ shift normally observed with calmodulin in electrophoretic gels, an observation that is consistent with this modification affecting the biological activity of the molecule. | SIGNOR-24778 |
P31946 | Q05513 | 0 | phosphorylation | down-regulates activity | 0.368 | Our results with the 14-3-3 mutants indirectly imply a new phosphorylation site, 130Ser (and to a lesser extent 141Thr), in 14-3-3b that regulates the association}dissociation of 14-3-3b and PKC-f. | SIGNOR-249035 |
P11309 | Q99814 | 1 | phosphorylation | up-regulates quantity by stabilization | 0.2 | PIM1 kinase directly phosphorylates HIF-1α at threonine 455, a previously uncharacterized site within its oxygen-dependent degradation domain. This phosphorylation event disrupts the ability of prolyl hydroxylases to bind and hydroxylate HIF-1α, interrupting its canonical degradation pathway and promoting constitutive transcription of HIF-1 target genes. Moreover, phosphorylation of the analogous site in HIF-2α (S435) stabilizes the protein through the same mechanism, indicating post-translational modification within the oxygen-dependent degradation domain as a mechanism of regulating the HIF-α subunits. | SIGNOR-277310 |

These results suggest that the PP5/PPP2R3C complex dephosphorylates PKA- and PKC-phosphorylated serine residues on P-gp | SIGNOR-272507 |
P12931 | P07355 | 1 | phosphorylation | up-regulates | 0.547 | Translocation requires the presence of the annexin 2 binding partner p11 (s100a10) and the phosphorylation of annexin 2 at tyr23 through a src-like tyrosine kinase-dependent mechanism both in vitro and in vivo. | SIGNOR-127872 |

We have now extended our previous studies to show that human casein kinase Idelta (hCKIdelta), the closest homologue to hCKIepsilon, associates with and phosphorylates hPER1 and causes protein instability. Furthermore, we observed that both hCKIdelta and hCKIepsilon phosphorylated and caused protein instability of human period 2 protein (hPER2). | SIGNOR-268000 |
P04637 | Q92630 | 0 | phosphorylation | up-regulates | 0.67 | Here, we demonstrate that the dual-specificity tyrosine-phosphorylation-regulated kinase 2 (dyrk2) directly phosphorylates p53 at ser46. these findings indicate that dyrk2 regulates p53 to induce apoptosis in response to dna damage. | SIGNOR-153544 |
Q15831 | P49841 | 1 | phosphorylation | down-regulates activity | 0.378 | In this regard, it was shown that LKB1 physically associates with PKC-zeta, which is known to inhibit GSK3beta kinase activity by promoting its phosphorylation.|Thus, inhibitory phosphorylation of GSK3beta by LKB1 and/or AKT may be a cardinal event leading to constitutive activation of Wnt and beta-catenin signaling (XREF_FIG). | SIGNOR-280148 |

P37173 | O75604 | 1 | phosphorylation | up-regulates activity | 0.2 | Here, we report the role of USP2a in promoting metastasis by facilitating TGF-β-triggered signaling. USP2a interacts with TGFBR1 and TGFBR2 upon TGF-β stimulation and removes K33-linked polyubiquitin chains from Lys502 of TGFBR1, promoting the recruitment of SMAD2/3. Simultaneously, TGFBR2 phosphorylates Ser207/Ser225 of USP2a, leading to the disassociation of SMAD2/3 from TGFBR1. | SIGNOR-273604 |

Smad2 is also acetylated by p/caf. The acetylation of smad2 was significantly higher than that of smad3. Lys(19) in the mh1 domain was identified as the major acetylated residue in both the long and short isoform of smad2.....acetylation of the short isoform of smad2 improves its dna binding activity in vitro and enhances its association with target promoters in vivo, thereby augmenting its transcriptional activity | SIGNOR-150273 |
