P02686 | P27361 | 0 | phosphorylation | down-regulates | 0.502 | Phosphorylation decreased the ability of mbp to polymerize actin and to bundle actin filaments but had no effect on the dissociation constant of the mbp-actin complex or on the ability of ca2+-calmodulin to dissociate the complex. The most significant effect of phosphorylation on the mbp-actin complex was a dramatic reduction in its ability to bind to negatively charged lipid bilayers. The identification of myelin basic protein (phosphorylation at -pro-arg-thr-pro-) as a substrate for the erk kinases (fig. 1) demonstrates that there are other determinants important for substrate recognition than those present in the originally identified consensus sequence. | SIGNOR-143481 |
P50148 | Q03431 | 2 | binding | up-regulates activity | 0.275 | This calciotropic hormone exerts its actions via binding to the PTH/PTH-related peptide receptor (PTH1R), which couples to multiple heterotrimeric G proteins, including Gs and Gq/11. | SIGNOR-270550 |
P0DP24 | P29474 | 2 | binding | up-regulates activity | 0.505 | Electrons flow from the C-terminal reductase domain of one NOS monomer to the N-terminal oxygenase domain of the other NOS monomer (Siddhanta et al., 1998). The primary mode of enzyme activation is the binding of calcium-bound calmodulin to the N-terminal CaM-binding domain. This facilitates a structure change and the flow of electrons from NADPH through the flavins to the oxygenase domain of the other eNOS monomer | SIGNOR-266323 |

Once there, raf proteins are activated and phosphorylated by different protein kinases. | SIGNOR-147327 |

O14641 | Q13467 | 2 | binding | up-regulates activity | 0.704 | Upon ligand binding, DVL proteins are recruited to Frizzled receptors at the plasma membrane and co-recruit cytoplasmic transducers, such as Axin, CK1 and GSK3 binding protein (GBP), presumably along with their partners, to promote ?-catenin-dependent signalling. | SIGNOR-258960 |
Q76L83 | P37231 | 2 | binding | up-regulates activity | 0.2 | ASXL2, which does not bind HP1, promotes differentiation by binding to PPARγ and increasing the level of methylated H3K4, leading to the elevation of PPARγ activity. Our genome-wide analysis confirmed the physiological roles of ASXL1 and ASXL2 in adipogenesis at the molecular level, supporting the hypothesis that ASXL1 is an authentic corepressor of PPARγ, whereas ASXL2 is a PPARγ coactivator, and that together ASXL1 and ASXL2 fine-tune adipogenesis via differential regulation of PPARγ. | SIGNOR-260063 |
Q15797 | O14595 | 0 | dephosphorylation | down-regulates | 0.5 | In human cells, rnai-mediated depletion of scp1 and scp2 increases the extent and duration of smad1 phosphorylation in response to bmp, the transcriptional action of smad1, and the strength of endogenous bmp gene responses. The present identification of the scp family as smad c-terminal phosphatases sheds light on the events that attenuate smad signaling and reveals unexpected links to the essential phosphatases that control rna polymerase ii in eukaryotes. | SIGNOR-148434 |
P31749 | P46937 | 1 | phosphorylation | down-regulates | 0.593 | One protein that associates with 14-3-3 in an akt-dependent manner is shown here to be the yes-associated protein (yap), which is phosphorylated by akt at serine 127, leading to binding to 14-3-3. Akt promotes yap localization to the cytoplasm, resulting in loss from the nucleus where it functions as a coactivator of transcription factors including p73. | SIGNOR-252593 |
Q96BR1 | Q9Y2I7 | 1 | phosphorylation | up-regulates activity | 0.461 | The Western blot in XREF_FIG demonstrates that SGK3 as well as PKB phosphorylate PIKfyve at position S318, thereby indicating that PIKfyve could be a physiological target of SGK3.|We here identify a novel mechanism involving NMDA receptor triggered, SGK3 dependent stimulation of PIKfyve with subsequent formation of PI (3,5) P 2, which modulates RAB11A facilitated vesicle transport to the plasma membrane, leading to an increased abundance of GluA1 receptor subunits in the plasma membrane. | SIGNOR-279113 |
P49841 | O15033 | 1 | phosphorylation | down-regulates quantity by destabilization | 0.316 | These experiments suggested that GSK3beta phosphorylation of FIEL1 is required for PIAS4 targeting, and FIEL1 residues P779 and phosphorylated T783 are both required for PIAS4 interaction |FIEL1 T783A mutant overexpression completely failed to decrease PIAS4 protein level. | SIGNOR-275528 |

P59594 | P07711 | 0 | cleavage | up-regulates activity | 0.2 | A cell-free membrane-fusion system demonstrates that engagement of receptor followed by proteolysis is required for SARS-CoV membrane fusion and indicates that cathepsin L is sufficient to activate membrane fusion by SARS-CoV S. These results suggest that SARS-CoV infection results from a unique, three-step process: receptor binding and induced conformational changes in S glycoprotein followed by cathepsin L proteolysis within endosomes. The requirement for cathepsin L proteolysis identifies a previously uncharacterized class of inhibitor for SARS-CoV infection. | SIGNOR-260218 |
P17612 | Q9UNF0 | 1 | phosphorylation | down-regulates activity | 0.2 | PKCα phosphorylates PACSIN2 at serine 313 in the linker region and decreases its membrane binding and tubulation activities.
