Polyubiquitination through SCFLFBXW8 was dramatically reduced by the depletion of ERK2 (lane 2). Furthermore, cyclin D1 polyubiquitination was largely prevented by the alanine-for-Thr286 substitution (T286A, lane 3), suggesting that phosphorylation of cyclin D1 at Thr286 is necessary for ubiquitination by SCFLFBXW8. | SIGNOR-271624 |

Q8TEW6 | P46108 | 2 | binding | up-regulates | 0.46 | Insulin receptor-phosphorylated irs5/dok4 associates with rasgap, crk, src, and fyn, but not phosphatidylinositol 3-kinase p85, grb2, shp-2, nck, or phospholipase cgamma src homology 2 domains, and activates mapk in cells. | SIGNOR-100996 |
P08243 | Q02447 | 0 | transcriptional regulation | up-regulates quantity by expression | 0.2 | Sp1 and Sp3 Activate Transcription Driven by the AS Promoter | SIGNOR-268020 |
Q96J02 | Q8NFZ5 | 1 | ubiquitination | down-regulates | 0.268 | Here we show that tnfa-mediated jnk activation accelerates turnover of the NF-kappaBinduced antiapoptotic protein c-flip, an inhibitor of caspase-8. This is not due to direct c-flip phosphorylation but depends on jnk-mediated phosphorylation and activationof the e3ubiquitin ligaseitch, which speci?cally Ubiquitinates c-flip and induces its proteasomal degradation. | SIGNOR-144453 |
P78527 | P42575 | 1 | phosphorylation | up-regulates | 0.297 | Here we show that dna damage induced by gamma-radiation triggers the phosphorylation of nuclear caspase-2 at the s122 site within its prodomain, leading to its cleavage and activation. This phosphorylation is carried out by the nuclear serine/threonine protein kinase dna-pkcs | SIGNOR-183895 |
A6ND36 | Q8N752 | 2 | binding | up-regulates quantity | 0.337 | We identified members of the FAM83 family of proteins as partners of CK1 in cells. All eight members of the FAM83 family (FAM83A–H) interacted with the α and α-like isoforms of CK1; FAM83A, -B, -E, and -H also interacted with the δ and ε isoforms of CK1. The intrinsic catalytic activity of CK1 is not affected by or required for the association of CK1 with FAM83 proteins. Our findings imply that the DUF1669 domains of FAM83 proteins anchor CK1 α, α-like, δ, and ε isoforms in specific subcellular compartments and potentially mediate their association with substrates. | SIGNOR-273753 |
P17612 | Q00536 | 1 | phosphorylation | down-regulates | 0.314 | Here, we report that cdk16 is activated by membrane-associated cyclin y (ccny). Treatment of transfected human cells with the protein kinase a (pka) activator forskolin blocked, while kinase inhibition promoted, ccny-dependent targeting of cdk16-green fluorescent protein (gfp) to the cell membrane. Ccny binding to cdk16 required a region upstream of the kinase domain and was found to be inhibited by phosphorylation of serine 153, a potential pka phosphorylation site. | SIGNOR-191623 |
P20333 | Q12933 | 2 | binding | up-regulates activity | 0.708 | Our analysis indicates that traf1 and traf2 are associated with the cytoplasmic domain of tnf-r2 in a heterodimeric complex in which traf2 contacts the receptor directly. | SIGNOR-34645 |
Q9HAW4 | O00311 | 0 | phosphorylation | up-regulates activity | 0.742 | Cdc7 phosphorylates Claspin in a manner dependent on AP and inhibits N\u2013C interaction.|Thus, Cdc7-ASK may activate DNA and PCNA bindings of Claspin through AP-mediated phosphorylation. | SIGNOR-279360 |
P53396 | P07948 | 0 | phosphorylation | up-regulates activity | 0.2 | We demonstrate the binding of PIP2 to the CoA-binding domain of ACLY and identify the six tyrosine residues of ACLY that are phosphorylated by Lyn. Three of them (Y682, Y252, Y227) can be also phosphorylated by Src and they are located in catalytic, citrate binding and ATP binding domains, respectively. PI3K and Lyn inhibitors reduce the ACLY enzyme activity, ACLY-mediated Acetyl-CoA synthesis, phospholipid synthesis, histone acetylation and cell growth. Thus, PIP2/PIP3 binding and Src tyrosine kinases-mediated stimulation of ACLY links oncogenic pathways to Acetyl-CoA-dependent pro-growth and survival metabolic pathways in cancer cells. | SIGNOR-274105 |
P45985 | Q9Y2U5 | 0 | phosphorylation | up-regulates activity | 0.612 | Both mekk2 and mekk3 are able to activate the jun kinase pathway in vivo. However, following routine immunoprecipitation in triton x-100, mekk2 but not mekk3 is able to effectively phosphorylate both sek-1 and mek-1 and to undergo autophosphorylation | SIGNOR-107695 |
Q06413 | Q9UPW0 | 0 | transcriptional regulation | up-regulates quantity by expression | 0.317 | Foxj3 transcriptionally activates Mef2c and regulates adult skeletal muscle fiber type identity. | SIGNOR-261606 |
Q969H0 | P31749 | 0 | phosphorylation | up-regulates activity | 0.41 | A reciprocal immunoprecipiation with anti-phospho-Akt substrate antibody followed by immunoblotting with anti-FLAG antibodies confirmed these findings (Fig. 1C). We concluded that Fbw7 is phosphorylated at S227 in vivo. Phosphorylation of Fbw7 is required for its biological activity. | SIGNOR-276328 |
P08754 | P21453 | 2 | binding | up-regulates activity | 0.504 | 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-256856 |
Q02962 | Q6ZW49 | 2 | binding | up-regulates activity | 0.571 | PTIP promotes assembly of the ALR complex and H3K4 methylation at a PAX2-binding DNA element. Without PTIP, Pax2 binds to this element but does not assemble the ALR complex | SIGNOR-251711 |

Q96EP5 | P28482 | 0 | phosphorylation | down-regulates activity | 0.2 | Further experiments showed that DAZAP1 was phosphorylated stoichiometrically in vitro by ERK2 (extracellular-signal-regulated protein kinase 2) at two Thr-Pro sequences (Thr269 and Thr315), and that both sites became phosphorylated in HEK-293 (human embryonic kidney 293) cells in response to PMA or EGF (epidermal growth factor), or RAW 264.7 macrophages in response to LPS. Phosphorylation of the ARE-binding protein DAZAP1 by ERK2 induces its dissociation from DAZ | SIGNOR-262970 |
P17542 | P17947 | 2 | binding | down-regulates activity | 0.439 | PU.1/Spi-1 binds to the human TAL-1 silencer to mediate its activity.By expressing a mutant protein containing only the ETS domain of PU.1 in human erythroleukemic HEL cells, we demonstrated that PU.1 mediates the transcriptional repression activity of the silencer. Our data clearly demonstrate that PU.1 mediates TAL-1 silencer activity | SIGNOR-256048 |
Q9Y2T4 | P12931 | 2 | binding | down-regulates activity | 0.2 | We show that PR55gamma binds c-SRC and modulates the phosphorylation of serine 12 of c-SRC, a residue we demonstrate to be required for JNK activation by c-SRC | SIGNOR-247966 |
P24844 | O43293 | 0 | phosphorylation | up-regulates | 0.487 | More than a dozen kinases have been reported to phosphorylate the rlcs of nm ii (fig. 2), including myosin light chain kinase (mlck;also known as mylk), rho-associated, coiled coil-containing kinase (rock), citron kinase, leucine zipper interacting kinase (zipk;also known as dapk3) and myotonic dystrophy kinase-related cdc42-binding kinase (mrck;also known as cdc42bp)6,34,45,46. These kinases phosphorylate rlcs on ser19, thr18 or both, to relieve the inhibition imposed on the myosin molecule by unphosphorylated rlcs and the head_head interaction outlined above. | SIGNOR-188789 |
Q9Y5H9 | Q9Y5G2 | 2 | binding | up-regulates activity | 0.2 | The clustered protocadherins comprise the largest subfamily of the cadherin superfamily and are predominantly expressed in the nervous system. Pcdh-alpha proteins interact with beta1-integrin to promote cell adhesion. They also form oligomers with Pcdh-gamma proteins at the same membrane sites. | SIGNOR-265688 |
Q8IXT1 | Q9UNE7 | 0 | ubiquitination | down-regulates quantity by destabilization | 0.322 | HSP70 recruits DDIAS to the CHIP E3 ligase, whereas CHIP promotes the ubiquitination of DDIAS.|However, the findings clearly demonstrated that HSP70 was solely involved in CHIP mediated proteasomal degradation of DDIAS. | SIGNOR-278784 |
O14786 | Q13214 | 2 | binding | up-regulates activity | 0.753 | Further examination of the composition of the functional Sema3B receptor revealed that, unlike Sema3A, which signals exclusively using the NP1 receptor, Sema3B utilizes both NP1 and NP2 for signal transduction. | SIGNOR-261814 |

Q04206 | O14757 | 0 | phosphorylation | up-regulates activity | 0.454 | Here we demonstrate that ARF induces the ATR- and Chk1-dependent phosphorylation of the RelA transactivation domain at threonine 505, a site required for ARF-dependent repression of RelA transcriptional activity. | SIGNOR-280225 |
Q13148 | Q9H2K2 | 2 | binding | up-regulates quantity by stabilization | 0.2 | Upon investigating the functional effect, we find that interaction with Tnks-1/2 inhibits the ubiquitination and proteasomal turnover of TDP-43, leading to its stabilization. We further show that proteasomal turnover of TDP-43 occurs preferentially in the nucleus; our data indicate that Tnks-1/2 stabilizes TDP-43 by promoting cytoplasmic accumulation, which sequesters the protein from nuclear proteasome degradation. | SIGNOR-262116 |
