Q9P244 | P78352 | 2 | binding | up-regulates activity | 0.775 | SALMs 1-3 contain a C-terminal PDZ-binding motif, which interacts with PSD-95, an abundant postsynaptic scaffolding protein, whereas SALM4 and SALM5 lack PDZ binding. Interactions between SALMs 1–3 and PSD-95 family proteinscould serve a number of functions. SALM1 and SALM2, which lack the ability to interact with a presynaptic ligand and thus cannot be directly targeted to sites of early synaptic adhesion, may require PSD-95 binding for their localization to early synapses. | SIGNOR-264095 |
P18669 | Q8IXJ6 | 0 | deacetylation | up-regulates activity | 0.279 | Here we report that PGAM is acetylated at lysine 100 (K100), an active site residue that is invariably conserved from bacteria, to yeast, plant, and mammals. K100 acetylation is detected in fly, mouse, and human cells and in multiple tissues and decreases PGAM2 activity. The cytosolic protein deacetylase sirtuin 2 (SIRT2) deacetylates and activates PGAM2. | SIGNOR-266517 |
Q14934 | P27361 | 0 | phosphorylation | up-regulates | 0.289 | The formation of rsk-nfatc4-dna transcription complex is also apparent upon adipogenesis. Bound rsk phosphorylates ser(676) and potentiates nfatc4 dna binding by escalating nfat-dna association. Ser(676) is also targeted by the erk map kinase, which interacts with nfat at a distinct region than rsk. Thus, integration of the erk/rsk signaling pathway provides a mechanism to modulate nfatc4 transcription activity. | SIGNOR-133276 |

Q9BYP7 | O95198 | 2 | binding | down-regulates quantity by destabilization | 0.476 | We found that KLHL2, as well as KLHL3, was co-immunoprecipitated with all four WNK isoforms. The direct interaction of KLHL2 with WNKs was confirmed on fluorescence correlation spectroscopy. Co-expression of KLHL2 and Cullin3 decreased the abundance of WNK1, WNK3 and WNK4 within HEK293T cells, and a significant increase of WNK4 ubiquitination by KLHL2 and Cullin3 was observed both in HEK293T cells and in an in vitro ubiquitination assay. These results suggest that KLHL2-Cullin3 also functions as an E3-ligase for WNK isoforms within the body. | SIGNOR-272121 |

Our findings also support the role of SREBP-2 as a transcriptional regulator of both the LDL receptor and PCSK9 in human enterocytes. | SIGNOR-254453 |
Q93008 | P62987 | 1 | cleavage | up-regulates quantity | 0.611 | Here we provide data suggesting that two of the four mammalian ubiquitin precursors, UBA52 and UBA80, are processed mostly post-translationally whereas the other two, UBB and UBC, probably undergo a combination of co- and post-translational processing. Using an unbiased biochemical approach we found that UCHL3, USP9X, USP7, USP5 and Otulin/Gumby/FAM105b are by far the most active DUBs acting on these precursors. | SIGNOR-270825 |
P09471 | P08913 | 2 | binding | up-regulates activity | 0.397 | 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).

Two amino-terminal sites on vimentin, Ser38 and Ser71, were identified as the major phosphorylation sites for Rho-kinase, and Ser71 was the most favored and unique phosphorylation site for Rho-kinase in vitro. | SIGNOR-248998 |
P48163 | Q96HS1 | 0 | dephosphorylation | up-regulates activity | 0.2 | PGAM5-mediated dephosphorylation of malic enzyme 1 (ME1) at S336 allows increased ACAT1-mediated K337 acetylation, leading to ME1 dimerization and activation, both of which are reversed by NEK1 kinase-mediated S336 phosphorylation. SIRT6 deacetylase antagonizes ACAT1 function in a manner that involves mutually exclusive ME1 S336 phosphorylation and K337 acetylation. | SIGNOR-275569 |

Moreover, T42 phosphorylation promotes the exposure and recognition of the target motif "KLYEQ" in the C-terminus of RKIP by chaperone Hsc70 and the subsequent degradation of RKIP via chaperone-mediated autophagy (CMA). | SIGNOR-276672 |

We have found that cdc2/cyclin b forms a complex with a fraction of warts in the centrosome and phosphorylates the ser613 site of warts during mitosisit can be speculated that phosphorylation of warts by cdc2/cyclin b promotes a protein complex formation on the mitotic apparatus at early mitosis, which may be required for subsequent activation of warts kinase at the metaphase-anaphase transition. | SIGNOR-94160 |

P28482 | P33076 | 1 | phosphorylation | up-regulates | 0.432 | We show in this study that the nuclear localized form of ciita is a predominantly phosphorylated form of the protein, whereas cytoplasmic ciita is predominantly unphosphorylated. Novel phosphorylation sites were determined to be located within a region that contains serine residues 286, 288, and 293. Double mutations of these residues increased nuclear ciita, indicating that these sites are not required for nuclear import. Erk1/2-mediated phosphorylation of ciita down-regulates ciita activity by priming it for nuclear export, thus providing a means for cells to tightly regulate the extent of antigen presentation. | SIGNOR-160609 |

Q9NRR4 | P49841 | 0 | phosphorylation | up-regulates activity | 0.278 | Our findings suggest that phosphorylation of Drosha at multiple sites including S300 promotes its translocation to the cytoplasm. Interestingly, GSK3beta can phosphorylate Drosha at S300 and S302 in vitro. This has been reported to promote the nuclear localization of Drosha under basal condition (Tang et al., 2011). Thus, it appears that phosphorylation of S300 by GSK3beta and p38 MAPK is involved in opposing processes. | SIGNOR-264846 |
