Q53HL2 | P33981 | 0 | phosphorylation | up-regulates | 0.461 | First, we confirmed that wild-type borealin is phosphorylated at the previously described sites t88, t94, t169, and t230 when present in complex with survivin borealin might be a substrate for mps1. In the case of wild-type borealin, the fast exchange between the monomeric and dimeric forms may allow mps1 to phosphorylate the monomer. In turn, mps1 may regulate borealin function by unfolding the c-terminal domain and/or shifting the population to the monomeric form. | SIGNOR-186151 |

The possible roles of mapkap kinase-1, mapkap kinase-2 and map kinase in the regulation of tyrosine hydroxylase in vivo are discussed. | SIGNOR-34674 |
Q8IYJ3 | P31749 | 0 | phosphorylation | down-regulates quantity | 0.355 | By mutagenesis analysis and subsequent immunoprecipitation (IP), we established that Akt phosphorylates JFC1 at serine 241. Phosphorylation did not alter the ability of JFC1 to bind to Rab27a. Instead, phosphorylation by Akt dramatically decreased when JFC1 was bound to Rab27a. Finally, we show that as a consequence of in vivo phosphorylation, JFC1 dissociates from the membrane, promoting JFC1 redistribution to the cytosol. | SIGNOR-273540 |

Q14524 | P06241 | 0 | phosphorylation | down-regulates | 0.293 | This study addresses the effects of the src family tyrosine kinase fyn on na(v)1.5 cardiac sodium channels. Sodium currents were acquired by whole cell recording on hek-293 cells transiently expressing na(v)1.5. Acute treatment of cells with insulin caused a depolarizing shift in steady-state inactivation, an effect eliminated by the src-specific tyrosine kinase inhibitor pp2 we provide evidence that this linker is a substrate for fyn in vitro, and that y1495 is a preferred phosphorylation site. | SIGNOR-135600 |

P45983 | P37231 | 1 | phosphorylation | down-regulates activity | 0.527 | The a/b domain of human ppargamma1 was phosphorylated in vivo, and this was abolished either by mutation of serine 84 to alanine (s84a) or coexpression of a phosphoprotein phosphatase. In vitro, this domain was phosphorylated by erk2 and jnk, and this was markedly reduced in the s84a mutant. Thus, phosphorylation of a mitogen-activated protein kinase site in the a/b region of ppargamma inhibits both ligand-independent and ligand-dependent transactivation functions. | SIGNOR-46518 |

Peak 1 represents an unknown kinase, whereas peak 2 contained ikkalpha, ikkbeta, ikkepsilon, and tbk1. collectively, our results provide evidence for at least five kinases that converge on ser-536 of p65 and a novel function for this phosphorylation site in the recruitment of components of the basal transcriptional machinery to the interleukin-8 promoter. | SIGNOR-129951 |

We identified two phosphorylation sites (S62, S110) where phosphomimetic substitutions increased Gld2 activity and one site (S116) that markedly reduced activity. Using mass spectrometry, we confirmed that HEK 293 cells readily phosphorylate the N-terminus of Gld2. We identified protein kinase A (PKA) and protein kinase B (Akt1) as the kinases that site-specifically phosphorylate Gld2 at S116, abolishing Gld2-mediated nucleotide addition. | SIGNOR-259405 |

The protein kinase ATM phosphorylates L3MBTL2, which recruits it to the DNA lesion by promoting the interaction between MDC1 and L3MBTL2. L3MBTL2 is subsequently ubiquitinated by RNF8, which acts as a docking site for RNF168, thereby recruiting the ubiquitin ligase to the damage site.
