Q96KK5	Q86Y13	0	monoubiquitination	up-regulates activity	0.2	2A-HUB catalyzes monoubiquitination of H2A at lysine 119, functioning as a combinatoric component of the repression machinery required for specific gene regulation programs. Thus, 2A-HUB mediates a selective repression of a specific set of chemokine genes in macrophages, critically modulating migratory responses to TLR activation.

P10636	P28482	0	phosphorylation	down-regulates activity	0.566	Using nanoelectrospray mass spectrometry, we have undertaken an extensive comparison of phosphorylation in vitro by several candidate tau kinases, namely, JNK, p38, ERK2, and glycogen synthase kinase 3beta (GSK3beta). Between 10 and 15 sites were identified for each kinase. The three MAP kinases phosphorylated Ser202 and Thr205 but not detectably Ser199, whereas conversely GSK3beta phosphorylated Ser199 but not detectably Ser202 or Thr205. Phosphorylated Ser404 was found with all of these kinases except JNK. The MAP kinases may not be strictly proline specific: p38 phosphorylated the nonproline sites Ser185, Thr245, Ser305, and Ser356, whereas ERK2 was the most strict. All of the sites detected except Thr245 and Ser305 are known or suspected phosphorylation sites in paired helical filament-tau extracted from Alzheimer brains. Thus, the three MAP kinases and GSK3beta are importantly all strong candidates as tau kinases that may be involved in the pathogenic hyperphosphorylation of tau in Alzheimer's disease.	SIGNOR-249416
P04637	Q09472	0	polyubiquitination	down-regulates quantity by destabilization	0.912	P53 is stabilized by the binding of p300 to the oncoprotein E1A, suggesting that p300 regulates p53 degradation. Purified p300 exhibited intrinsic ubiquitin ligase activity that was inhibited by E1A. In vitro, p300 with MDM2 catalyzed p53 polyubiquitination, whereas MDM2 catalyzed p53 monoubiquitination. E1A expression caused a decrease in polyubiquitinated but not monoubiquitinated p53 in cells. Thus, generation of the polyubiquitinated forms of p53 that are targeted for proteasome degradation requires the intrinsic ubiquitin ligase activities of MDM2 and p300.	SIGNOR-271418

Using nanoelectrospray mass spectrometry, we have undertaken an extensive comparison of phosphorylation in vitro by several candidate tau kinases, namely, JNK, p38, ERK2, and glycogen synthase kinase 3beta (GSK3beta). Between 10 and 15 sites were identified for each kinase. The three MAP kinases phosphorylated Ser202 and Thr205 but not detectably Ser199, whereas conversely GSK3beta phosphorylated Ser199 but not detectably Ser202 or Thr205. Phosphorylated Ser404 was found with all of these kinases except JNK. The MAP kinases may not be strictly proline specific: p38 phosphorylated the nonproline sites Ser185, Thr245, Ser305, and Ser356, whereas ERK2 was the most strict. All of the sites detected except Thr245 and Ser305 are known or suspected phosphorylation sites in paired helical filament-tau extracted from Alzheimer brains. Thus, the three MAP kinases and GSK3beta are importantly all strong candidates as tau kinases that may be involved in the pathogenic hyperphosphorylation of tau in Alzheimer's disease.

If that is the case, then our genetic results support the notion that p190 is negatively regulated by both Src and integrin.|The Src family of tyrosine kinases phosphorylate mammalian p190.

The results showed that PKA promoted the phosphorylation of calpastatin, and a high phosphorylation level was maintained during incubation. Phosphorylation at serine 133 of calpastatin enhanced its inhibition on calpain activity by maintaining its structural stability, thus inhibiting the tenderization of meat.

Mage-11 ser-174 appears to be a post-translational regulatory site phosphorylated by erk1, based on the inhibitory effect of the s174a mutation in the context of shorter ar nh2-terminal fragments (19), and the greater transcriptional activity of gal-mage-11 fusion proteins containing the s174d phosphomimetic.

We found that the human papillary renal cell carcinoma-associated proteinprccinteracts with the cell cycle control proteinmad2b, and translocates this protein to the nucleus where it exerts its mitotic checkpoint function.

PXDN expression in response to H2O2 and the Nrf2-specific inducers, tert-butylhydroquinone (tBHQ) and sulforaphane (SFN), was determined by western blotting and immunofluorescence microscopy, in HeLa and HEK293 cells.We found that Nrf2 binds to and increases luciferase reporter gene expression from the PXDN promoter via a putative Nrf2-binding site. In summary, we show that PXDN is a novel target of the redox sensitive transcription factor Nrf2.

Two kinases, i.e. abelson-tyrosine protein kinase (ABL)1 and Src were identified as eNOS Tyr81 kinases as their inhibition and down-regulation significantly reduced the basal and Yoda1-induced tyrosine phosphorylation and activity of eNOS.
