O00330 | Q99626 | 2 | binding | down-regulates activity | 0.2 | In the heterologous cell line BHK-21, Pdx1 inhibited by 60 to 80% the activation of the alpha-cell specific element G1 conferred by Pax-6 and/or Cdx-2/3. Although Pdx1 could bind three AT-rich motifs within G1, two of which are binding sites for Pax-6 and Cdx-2/3, the affinity of Pdx1 for G1 was much lower as compared to Pax-6. In addition, Pdx1 inhibited Pax-6 mediated activation through G3, to which Pdx1 was unable to bind. Moreover, a mutation impairing DNA binding of Pdx1 had no effect on its inhibition on Cdx-2/3. Since Pdx1 interacts directly with Pax-6 and Cdx-2/3 forming heterodimers, we suggest that Pdx1 inhibits glucagon gene transcription through protein to protein interactions with Pax-6 and Cdx-2/3. | SIGNOR-254904 |

In the present paper we have identified CapZIP as a protein that is phosphorylated exceptionally rapidly by several SAPKs in vitro (Figure 4), and which is expressed in muscles and immune cells. Both MAPKAP-K2 and MAPKAP-K3 phosphorylated CapZIP at Ser-179 in vitro. An important clue to the function of CapZIP and its phosphorylation came from the finding that it binds to the actin-capping protein CapZ (Figure 7A), and that cellular stresses trigger the dissociation of these two proteins (Figure 7B).Such an effect is presumably lost when CapZIP is phosphorylated and dissociates from CapZ. | SIGNOR-263080 |

P06493 | P19525 | 0 | phosphorylation | down-regulates | 0.328 | Our findings demonstrate that (i) pkr, ser/thr kinase, phosphorylates its new substrate cdc2 at the tyr 4 residue, (ii) pkr-mediated tyr 4-phosphorylation facilitates cdc2 ubiquitination and proteosomal degradation | SIGNOR-164809 |
P19484 | P28482 | 0 | phosphorylation | down-regulates activity | 0.413 | Evidence for ERK2-mediated TFEB phosphorylation came from ERK2-TFEB coimmuno-precipitation (fig.

P68400 | P18848 | 1 | phosphorylation | down-regulates quantity by destabilization | 0.2 | By using mutants of ATF4 we identified serine 215 as the main CK2 phosphorylation site. The ATF4 S215A mutant turned out to be more stable than the wild-type form. | SIGNOR-276425 |
P21333 | Q8WUP2 | 2 | binding | up-regulates activity | 0.888 | Kindlin binds migfilin tandem LIM domains and regulates migfilin focal adhesion localization and recruitment dynamics. Two integrin-binding proteins present in FAs, kindlin-1 and kindlin-2, are important for integrin activation, FA formation, and signaling. By binding filamin, migfilin provides a link between kindlin and the actin cytoskeleton. | SIGNOR-266105 |
P19419 | Q16539 | 0 | phosphorylation | up-regulates | 0.526 | We demonstrate here that elk-1 is barely activated by a third subclass of map kinases (p38), most likely because the critical residues ser383 and ser389 are poorly phosphorylated by p38 map kinase. | SIGNOR-47630 |
Q9UNH5 | Q96R06 | 1 | dephosphorylation | down-regulates activity | 0.2 | We also demonstrate that Cdc14A dephosphorylates Astrin, and therefore the overexpression of Cdc14A sequesters Astrin in the centrosome and results in aberrant chromosome alignment. | SIGNOR-277066 |
P53350 | P37840 | 1 | phosphorylation | down-regulates activity | 0.351 | Polo-like kinase (plk) family (plk1, plk2, and plk3) phosphorylate alpha-syn and beta-syn specifically at ser-129 and ser-118, respectively. Polo-like kinase 2 (plk2) phosphorylates alpha-synuclein at serine 129 in central nervous system. The membrane association of pd-linked mutant alpha -synuclein, but not wild-type -synuclein, was increased by serine 129 phosphorylation. | SIGNOR-189045 |

Q96L92 | Q16539 | 0 | phosphorylation | down-regulates activity | 0.2 | Altogether, our study suggests that MAPK11 and MAPK14 mediate the phosphorylation of SNX27 at Ser51 in vitro and in vivo. | SIGNOR-279069 |
P11388 | P49841 | 0 | phosphorylation | down-regulates quantity by destabilization | 0.348 | This study also reports the novel finding that topoIIα may be a target of GSK3β phosphorylation. Evidence suggests that CK2 serves as a priming kinase, through phosphorylation at Ser1365, for GSK3β-mediated phosphorylation at Ser1361. | SIGNOR-276301 |
Q14524 | P61328 | 2 | binding | down-regulates activity | 0.579 | Sodium channel fast inactivation is modulated by alpha subunit interaction with a family of cytoplasmic proteins termed fibroblast growth factor homologous factors (FHFs). In this paper, we report that all A-type FHFs exert rapid onset long-term inactivation on Nav1.6 and other sodium channels. | SIGNOR-253416 |

P23467 | P35968 | 1 | dephosphorylation | down-regulates activity | 0.454 | VE-PTP/VEGFR2 complex formation resumes with time, leading to dephosphorylation and deactivation of VEGFR2 (right). B) In VE-PTP-deficient cells, such as after siRNA treatment, VEGFR2 activation (middle) is exaggerated, leading to increased phosphorylation at the Y951 and Y1175 phosphorylation sites | SIGNOR-248441 |
Q14186 | Q14209 | 2 | binding | up-regulates activity | 0.738 | The transcriptionally active forms of E2F are heterodimers composed of one polypeptide encoded by the E2F gene family and one polypeptide encoded by the DP gene family.In transfected cells, DP-1 did not accumulate in the nucleus unless it was coexpressed with the heterodimeric partners E2F-1, E2F-2, or E2F-3. | SIGNOR-240550 |
P56693 | Q13287 | 2 | binding | up-regulates activity | 0.429 | we identify an association of Sox10 with the N-myc interactor Nmi. Nmi modulated the transcriptional activity of Sox10 in reporter gene assays. Nmi effects varied between different Sox10 target gene promoters, indicating that Nmi function in vivo may be promoter-specific. | SIGNOR-225599 |

Q06187 | Q15417 | 1 | phosphorylation | up-regulates quantity | 0.2 | Co-expression of calponin-3 with various kinases in S2 Schneider cells promoted a phosphorylation of calponin-3 by Syk, but also by the Tec family kinase Btk. | SIGNOR-280196 |
Q9NR31 | P53992 | 2 | binding | up-regulates quantity | 0.709 | Biogenesis of COPII vesicles is initiated by the activation of the small guanosine triphosphate (GTP)-binding protein secretion-associated Ras-related protein 1 (Sar1) at specialized subdomains of the ER, called ER exit sites (ERES) or transitional ER (tER). Membrane-bound Sar1 then recruits the inner COPII coat subcomplex, the Sec23/24 heterodimer. | SIGNOR-265302 |
P29350 | Q96P31 | 2 | binding | up-regulates activity | 0.39 | Tyrosine phosphorylation of SPAP2a by c-Src and in vitro. Tyrosine-phosphorylated SPAP2 is specifically associated with SH2 domain-containing tyrosine kinases Syk and Zap70 and SH2 domain-containing tyrosine phosphatases SHP-1 and SHP-2. Site-specific mutagenesis studies revealed that tyrosyl residues 650 and 662 embedded in the ITIMs are responsible for the binding of Syk and Zap70 while tyrosyl residues 692 and 722 embedded in the ITIMs are involved in interactions with SHP-1 and SHP-2. | SIGNOR-274013 |

O00398 | P08754 | 2 | binding | up-regulates activity | 0.2 | 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-256869 |

The results demonstrated that majority of the KDMs were similarly induced (KDM2A, KDM2B, KDM3A, KDM4B, KDM4C, KDM4D, KDM5A, KDM5B, KDM5C, KDM6B, and KDM7A) or repressed (KDM NO66 and KDM1A) by both HIF-1a and HIF-2a. | SIGNOR-271568 |

In conclusion, the present study showed that PP4 may be a novel regulator in hepatic lipogenesis through dephosphorylating ACC1 on serine 79, suggesting that PP4 may be a promising therapeutic target in lipid metabolism disorders. | SIGNOR-267724 |

Q14195 | Q92630 | 0 | phosphorylation | up-regulates activity | 0.364 | Together, these results suggest that crmp4 is able to increase neurite formation and elongation in neurons, although not as potently as crmp2, and that this process is regulated by ser522/ser518/thr514/thr509 phosphorylation in both cases. We demonstrate that cdk5 primes crmp2 and crmp4 for subsequent phosphorylation by gsk3, whereas dyrk2, phosphorylates and primes only crmp4 in vitro | SIGNOR-145987 |
