Q9UJP4 | Q96GD4 | 2 | binding | up-regulates activity | 0.507 | KLHL21 directly binds to Aurora B and mediates ubiquitination of Aurora B in vitro. In contrast to KLHL9 and KLHL13, KLHL21 localizes to midzone microtubules in anaphase and recruits Aurora B and Cul3 to this region. Together, our results suggest that different Cul3 adaptors nonredundantly regulate Aurora B during mitosis, possibly by ubiquitinating different pools of Aurora B at distinct subcellular localizations. | SIGNOR-271848 |

P12931 | Q04760 | 1 | phosphorylation | up-regulates activity | 0.2 | We show that Glo1 activity is promoted by phosphorylation on Tyrosine 136 via multiple kinases. Glo1 Y136 is phosphorylated by multiple different kinases including all members of the Src family. Depletion of multiple different kinases led to a partial reduction in Glo1(Y136) phosphorylation. These included members of the Src family (Src, Yes1, FGR, and the related Abl1), and of the FAK, EPHA, FGFR, and VEGFR families (Figure 2B), suggesting phosphorylation of Glo1 on Y136 by multiple different kinases. In vitro kinase assays revealed that all the members of the Src family, as well as Epha5 and VEGFR3, can efficiently phosphorylate recombinant Glo1 on Y136 (Figure 2C–D). | SIGNOR-276189 |
Q13224 | Q13554 | 0 | phosphorylation | up-regulates activity | 0.606 | By peptide mapping, automated sequencing, and mass spectrometry, we identified the major site of phosphorylation on the fusion protein as Ser-383, corresponding to Ser-1303 of full-length NR2B. The Km for phosphorylation of this site in the fusion protein was approximately 50 nM, much lower than that of other known substrates for CaM kinase II, suggesting that the receptor is a high affinity substrate. We show that serine 1303 in the full-length NR2B and/or the cognate site in NR2A is a major site of phosphorylation of the receptor both in the postsynaptic density fraction and in living hippocampal neurons. | SIGNOR-250688 |

P08581 | P23470 | 0 | dephosphorylation | down-regulates activity | 0.317 | PTPRG activation by the P1-WD peptide affected the tyrosine phosphorylation of several signaling molecules. Data analysis identified 31 molecules whose phosphorylation was modified in a statistically significant manner (Table I). inhibition of ABL1, BMX, BTK, DAB1, ITGB1, JAK2, KDR, KIT, LIMK1, MET, PDGFRB, SHC1, and VCL correlates with tyrosine dephosphorylation. In contrast, SRC inhibition correlates with hyperphosphorylation of the inhibitory Tyr530 residue and with dephosphorylation of the activatory Tyr419. Moreover, CDK2 and CTTN inhibition correlates with a hyperphosphorylation of the inhibitory Tyr15 and Tyr470, respectively. In contrast, a subgroup of 13 proteins, including BLNK, DOK2, ERBB2, GRIN2B, INSR, PDGFRA, PRKCD, PXN, STAT1, STAT2, STAT3, STAT5A, and ZAP70, appears to be activated by PTPRG activity. | SIGNOR-254712 |
