Surprisingly, we did not find MYCBP2-dependent ubiquitylation of SUMOylated RanGAP1 but instead a strong inhibition of the ubiquitin ligase activity of MYCBP2 in the presence of SUMOylated RanGAP1, as determined by the presence of ubiquitylated proteins. this effect was specific for SUMOylated RanGAP1, because the unmodified form of RanGAP1 did not affect MYCBP2-dependent protein ubiquitylation. , SUMOylated RanGAP1 inhibited the ubiquitin ligase activity of MYCBP2, and it is tempting to speculate that SUMOylated RanGAP1 inhibits the ubiquitin ligase activity of MYCBP2 to ensure MYCBP2 silencing during its transport to the nucleus | SIGNOR-261203 |

Q13618 | Q9Y4X5 | 1 | binding | up-regulates activity | 0.314 | Here, we provide evidence that Ariadne RBR E3 ubiquitin ligases such as TRIAD1 and HHARI can bind and be activated by CRL complexes. Whereas TRIAD1 specifically associates with CUL5–RBX2, HHARI is more promiscuous towards cullin types and associates with RBX1-associated cullins 1, 2, 3, and 4A. Interestingly, both TRIAD1 and HHARI show a strong preference for binding the neddylated form of the cullin. Our data suggest a novel function of NEDD8 in directing specific CRLs to Ariadne RBR ligases, which in turn exert influence on the levels of their cognate neddylated cullin. | SIGNOR-268846 |

CDK5RAP2 was detected in the CDC20 immunocomplex as well (Fig. 3B). | SIGNOR-260311 |
Q9GZV5 | Q15361 | 1 | binding | up-regulates | 0.313 | Taz is a coactivator for pax8 and ttf-1, two transcription factors involved in thyroid differentiation. / we show that this interaction leads to a significant enhancement of the transcriptional activity of pax8 and ttf-1 on the thyroglobulin promoter thus suggesting a role of taz in the control of genes involved in thyroid development and differentiation. | SIGNOR-182296 |
Q6W2J9 | O15379 | 1 | binding | up-regulates activity | 0.313 | BCoR can interact w Because HDACs appear to be involved in repression by an increasing number of transcriptional repressors, we tested whether BCoR can associate with HDACs. BCoR can interact with HDAC1, HDAC3, and HDAC-B/5 more strongly than with HDAC-A/4, HDAC-C, HDAC-D, and HDAC-E. | SIGNOR-252237 |

Q02156 | P28329 | 1 | phosphorylation | up-regulates | 0.312 | We show that chat is differentially phosphorylated by protein kinase c (pkc) isoforms on four serines (ser-440, ser-346, ser-347, and ser-476) and one threonine (thr-255). This phosphorylation is hierarchical, with phosphorylation at ser-476 required for phosphorylation at other serines. Phosphorylation at some, but not all, sites regulates basal catalysis and activation | SIGNOR-129312 |
P35408 | P63096 | 1 | binding | up-regulates activity | 0.312 | Here we systematically quantified ligand-induced interactions between 148 GPCRs and all 11 unique G alpha subunit C-termini. For each receptor, we probed chimeric G alpha subunit activation via a transforming growth factor-alpha (TGF alpha) shedding response in HEK293 cells lacking endogenous Gq/11- and G12/13- signaling. | We defined positive coupling if any member of the subfamily scored LogRAi ≥ -1 and negative coupling if all of the members scored LogRAi < -1 (Figure 3A-B). 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. | SIGNOR-257032 |
P05154 | P02751 | 1 | binding | down-regulates activity | 0.312 | SERPINA5 inhibits HCC cell migration by directly interacting with fibronectin. SERPINA5 disrupts the fibronectin–integrin β1 signaling pathway. | SIGNOR-265881 |

FBXO22 mediates BAG3 ubiquitination and degradation that requires ERK-dependent BAG3 phosphorylation at S377. | SIGNOR-277318 |
P27361 | Q9HAV4 | 1 | phosphorylation | down-regulates activity | 0.312 | Here we show that ERK suppresses pre-miRNA export from the nucleus through phosphorylation of exportin-5 (XPO5) at T345/S416/S497. After phosphorylation by ERK, conformation of XPO5 is altered by prolyl isomerase Pin1, resulting in reduction of pre-miRNA loading. | SIGNOR-262985 |

O00141 | P14672 | 1 | phosphorylation | up-regulates activity | 0.312 | We evaluated the putative role of sgk1 in the modulation of glut4. Coexpression of the kinase along with glut4 in xenopus oocytes stimulated glucose transport. The enhanced glut4 activity was paralleled by increased transporter abundance in the plasma membrane. Disruption of the sgk1 phosphorylation site on glut4 ((s274a)glut4) abrogated the stimulating effect of sgk1. In summary, sgk1 promotes glucose transporter membrane abundance via glut4 phosphorylation at ser274. | SIGNOR-236653 |

Q13464 | P14136 | 1 | phosphorylation | down-regulates activity | 0.312 | We report here that aurora-b phosphorylates gfap and desmin in vitro, and this phosphorylation leads to a reduction in filament forming ability. The sites phosphorylated by aurora-b;thr-7/ser-13/ser-38 of gfap, and thr-16 of desmin are common with those related to rho-associated kinase (rho-kinase), which has been reported to phosphorylate gfap and desmin at cleavage furrow during cytokinesis.

Q92835 | P16885 | 1 | dephosphorylation | down-regulates activity | 0.312 | An adaptor protein Dok-3 mediates the suppressive function of LYN. The Dok-3 phosphorylated by LYN upon BCR stimulation forms a complex with GRB2, which allows it to enter into the signalosome and associate with activation of SHIP protein. This translocation facilitates the efficient inhibition of PLCc2 and SYK from activation, subsequently resulting in the suppression of downstream Ca2+ signaling. | SIGNOR-268455 |

P78352 | Q9HCD6 | 1 | binding | up-regulates activity | 0.312 | In the present study, we provide evidence that TANC1 and its close relative TANC2 regulate dendritic spines and excitatory synapses. our results indicate that TANC-dependent spine/synapse maintenance requires TANC binding to PSD-95, which promotes synaptic localization of TANC proteins. Thus, it is likely that interaction with PSD-95 concentrates TANC proteins at synapses, where they play a role in mediating PSD-95-dependent maintenance of spines and synapses. | SIGNOR-266895 |

This phosphorylation of USP20 correlates with a characteristic SDS-PAGE mobility shift of the protein, blocks its deubiquitinase activity, promotes its dissociation from the activated β2AR complex, and facilitates trafficking of the ubiquitinated β2AR to autophagosomes, which fuse with lysosomes to form autolysosomes where receptors are degraded. | SIGNOR-273795 |

Q4V328 | P45983 | 1 | binding | up-regulates activity | 0.311 | To examine whether GRASP‐1 interacts with MEKK1 and JNK1 in neurons, co‐immunoprecipitation experiments were performed with detergent‐solubilized extracts from cultured cortical neurons. Both antiJNK1 and anti‐MEKK1 antibodies immunoprecipitated GRASP‐1 from neuronal lysates. These results suggest that GRASP‐1 interacts with MEKK1 and JNK1 in neurons. GRASP-1 potently activates JNK pathway signaling, with no effect on ERK signaling. Such JNK pathway activating activity requires binding of GRASP-1 to both JNK and the upstream JNK pathway activator MEKK-1. | SIGNOR-260639 |
