Q13153	P62714	0	dephosphorylation	down-regulates activity	0.2	Both sites were dephosphorylated with the same kinetics; the anti-Ser(P)198 antibody was subsequently used as it exhibited lower background staining. Direct comparison of PP2Cα with purified PP1 and PP2A lead us to conclude that at the same molar ratio PP2Cα was the most efficient in dephosphorylating PAK1 (Fig. 1D). In this case we monitored two autophosphorylation sites in the Pak1 N-terminal regulatory region (Ser57 and Ser198/203) using phosphospecific antibodies: both sites showed the same kinetics of inactivation.

Here, using a site- and phosphorylation state-specific antibody, we found that the expression of dominant active RhoA in COS7 cells induced moesin phosphorylation and the formation of microvilli-like structures at apical membranes where the Thr558-phosphorylated moesin accumulated, whereas the expression of dominant negative Rho-kinase inhibited both of these processes.

This leads to the inactivation and release of glycogen synthase kinase 3b from its complex with axin, thereby relieving the inhibitory phosphorylation of b-catenin and activating its signaling pathway.

We also found that SUN1 interacted with SPDYA, an activator of CDK2. \| Taken together, we speculate that speedy A is likely capable of interacting with both telomeres and the LINC complex and thus might function as the missing linkage between telomeres and the LINC complex during prophase I, stabilizing the telomere–NE connection	SIGNOR-263301

Native PTPN22 dephosphorylated Lck and Zap70 at their activating tyrosine residues Tyr-394 and Tyr-493, respectively, but not at the regulatory tyrosines Tyr-505 (Lck) or Tyr-319 (Zap70). Native PTPN22 also dephosphorylated TCRzeta in vitro and in cells, and its substrate trap variant co-immunoprecipitated with TCRzeta when both were coexpressed in 293T cells, establishing TCRzeta as a direct substrate of PTPN22.

Overexpression of TGF-alpha stabilizes Naked2 protein in an EGF receptor (EGFR)-independent manner; a physical interaction between the cytoplasmic tail of TGF-alpha and Naked2 is necessary and sufficient for this protection.

Since MyoD is not expressed under these conditions, it cannot bind to these genes; ChIP assays demonstrated that HDAC2 also was not present on the Ckm, Des and Acta1 regulatory sequences under these conditions (Figure _(Figure6B).6B).

SAG (Sensitive to Apoptosis Gene), also known as RBX2 (RING box protein 2), ROC2 (Regulator of Cullins 2), or RNF7 (RING Finger Protein 7), was originally cloned in our laboratory as a redox inducible antioxidant protein and later characterized as the second member of the RBX/ROC RING component of the SCF (SKP1-CUL-F-box Proteins) E3 ubiquitin ligase. by forming a complex with other components of the SCF E3 ligase, SAG promotes ubiquitination and degradation of a number of protein substrates, including c-JUN, DEPTOR, HIF-1α, IκBα, NF1, NOXA, p27, and procaspase-3, thus regulating various signaling pathways and biological processes.

Modulation of human nuclear receptor lrh-1 activity by phospholipids and shpthe human nuclear receptor liver receptor homolog 1 (hlrh-1) plays an important role in the development of breast carcinomas. This orphan receptor is efficiently downregulated by the unusual co-repressor shp

Overexpression of Myc-KAT8 increased the acetylation level of endogenous FASN by 2.2-fold (Fig. 3C). In contrast, knockdown of KAT8 decreased endogenous FASN acetylation by as much as 55%

Accordingly, for the OTDP, the binding affinity and activity of a large number of opiate compounds have been tested at μ-, δ-, and κ-opiate receptors. Binding studies were originally conducted in guinea pig brain membranes, and subsequent studies have been carried out in CHO cells transfected with human receptors. Table 7 shows a biochemical method for determining activity and potency of opioid compounds, stimulation of [35S]GTPγS binding in membranes from cells transfected with human μ, δ, or κ receptors.

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). ROC analysis gives AUC = 0.78 (Figure S4A) when considering high-confidence known coupling data and suggested a threshold of LogRAi ≥ -1.0 for defining true couplings. | The score associated to this interaction has a LogRAi ≥ -1.0.
