In summary, the above findings suggest that NIRF tightly cooperates with the core cell cycle machinery and induces G1 arrest, which is accompanied by ubiquitination of cyclins D1 and E1. | SIGNOR-271885 |

As tyrosine phosphorylation of cd72 strongly correlates with the ability of the bcr to deliver growth-inhibitory/apoptosis-inducing signals (figure 4), our results suggest that shp-1-catalyzed dephosphorylation of cd72 may antagonize these signals. | SIGNOR-60155 |

It is demonstrated that each of the three RING peroxins Pex2, Pex10, and Pex12 exhibits ubiquitin-protein isopeptide ligase activity. Our results show that Pex2 mediates the Ubc4-dependent polyubiquitination whereas Pex12 facilitates the Pex4-dependent monoubiquitination of Pex5.While polyubiquitinated Pex5 is degraded by the proteasome, monoubiquitinated Pex5 is destined for a new round of the receptor cycle. | SIGNOR-253020 |
O14543 | P42224 | 0 | transcriptional regulation | up-regulates quantity by expression | 0.677 | Expression of SOCS1 and SOCS3 is regulated primarily by activation of STAT1 and STAT3, respectively, although their expression can be mediated through other signaling cascades, including the mitogen activated protein kinase (MAPK) and nuclear factor-kappa B (NF-kappaB) pathways. | SIGNOR-249565 |

Their phosphorylation leads to protein stabilization (3, 13, 20, 41). Threonine 325 and threonine 331 are secondary targets of Erk1/2; their modification occurs only when serines 362 and 374 are phosphorylated and Erk1/2 activation is sufficiently sustained (37, 38).

In the present study, we identify protein phosphatase 1 (PP1) as a negative regulator in the p53 signaling pathway. PP1 directly interacts with Mdmx and specifically dephosphorylates Mdmx at Ser367. The dephosphorylation of Mdmx increases its stability and thereby inhibits p53 activity. | SIGNOR-248577 |

Furthermore, serines 11 and 92 are required for snail1-mediated emt and cell viability, respectively.

Q14185 | P63000 | 1 | guanine nucleotide exchange factor | up-regulates activity | 0.735 | We found in this study that AUTS2 is involved in Rac1 activation via P-Rex1 and the Elmo2/Dock180 complex, but not STEF or Tiam1, for the lamellipodia formation in N1E-115 cells. However, the enhancement of neurite elongation in primary neurons by AUTS2 expression is specifically mediated by the Elmo2/Dock180 complex. These results suggested that several Rac-GEFs differentially or cooperatively participate in Rac1 activation to promote neuronal migration and neurite outgrowth. | SIGNOR-266822 |

Q96MT8 | P24941 | 1 | relocalization | up-regulates activity | 0.372 | Primary microcephaly (MCPH) associated proteins CDK5RAP2, CEP152, WDR62 and CEP63 colocalize at the centrosome. We found that they interact to promote centriole duplication and form a hierarchy in which each is required to localize another to the centrosome, with CDK5RAP2 at the apex, and CEP152, WDR62 and CEP63 at sequentially lower positions. MCPH proteins interact with distinct centriolar satellite proteins; CDK5RAP2 interacts with SPAG5 and CEP72, CEP152 with CEP131, WDR62 with MOONRAKER, and CEP63 with CEP90 and CCDC14. These satellite proteins localize their cognate MCPH interactors to centrosomes and also promote centriole duplication. Consistent with a role for satellites in microcephaly, homozygous mutations in one satellite gene, CEP90, may cause MCPH. The satellite proteins, with the exception of CCDC14, and MCPH proteins promote centriole duplication by recruiting CDK2 to the centrosome. | SIGNOR-271725 |
