Mitotic phosphorylation of blm was partially dependent on atm, and phosphorylation sites on blm were identified. A phosphospecific antibody against one of these sites (thr-99) revealed radiation-induced phosphorylation, which was defective in ataxia-telangiectasia cells. These data suggest that atm and blm function together in recognizing abnormal dna structures by direct interaction and that these phosphorylation sites in blm are important for radiosensitivity status but not for sce frequency.

Msx-1 is a potent transcriptional repressor and that this activity is independent of its DNA binding function. Here we show that Msx-1 interacts directly with the TATA binding protein (TBP) but not with several other general transcription factors. This interaction is mediated by the Msx-1 homeodomain, specifically through residues in the N-terminal arm. These same N-terminal arm residues are required for repression by Msx-1, suggesting a functional relationship between TBP association and transcriptional repression.

We have previously identified two human genes, gxylt1 and gxylt2, encoding glucoside xylosyltransferases responsible for the transfer of xylose to o-linked glucose. The identity of the enzyme further elongating the glycan to generate the final trisaccharide xylose-xylose-glucose, however, remained unknown. Here, we describe that the human gene c3orf21 encodes a udp-xylose:alfa-xyloside alfa1,3-xylosyltransferase, acting on xylose-alfa1,3-glucosebeta1-containing acceptor structures. We have, therefore, renamed it xxylt1 (xyloside xylosyltransferase 1). Xxylt1 cannot act on a synthetic acceptor containing an alfa-linked xylose alone, but requires the presence of the underlying glucose. Activity on notch egf repeats was proven by in vitro xylosylation of a mouse notch1 fragment recombinantly produced in sf9 insect cells, a bacterially expressed egf repeat from mouse notch2 modified in vitro by rumi and gxylt2 and in vivo by co-expression of the enzyme with the notch1 fragment. The enzyme was shown to be a typical type ii membrane-bound glycosyltransferase localized in the endoplasmic reticulum.

SHANK proteins then bind to the actin cytoskeleton and to Homer protein, which in turn interacts with mGluRs.

We found that jnk phosphorylated ser-121 and thr-163 of mcl-1 in response to stimulation with h(2)o(2) and that transfection of unphosphorylatable mcl-1 resulted in an enhanced anti-apoptotic activity in response to stimulation with h(2)o(2). Jnk-dependent phosphorylation and thus inactivation of mcl-1 may be one of the mechanisms through which oxidative stress induces cellular damage.

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.

NFE2L2 is stabilized and translocates to the nucleus, where it dimerizes with sMAF proteins. This complex binds to AREs to mediate the transcription of genes involved in iron metabolism, GSH metabolism, and ROS detoxification. NFE2L2 directly binds to the promoter region of SLC7A11, leading to increased expression of this transporter, which in turn contributes to the resistance to ferroptosis and to radiotherapy

The in vivo existence of an SF-1 corepressor complex consisting of DAX-1, RNF31, and SMRT at the steroidogenic promoters of the human StAR and CYP19 genes. We demonstrate that RNF31 is necessary for the stable association of the DAX-1 corepressor complex with chromatin-bound SF-1, thereby inhibiting the recruitment of coactivators and Pol II and controlling basal transcription levels of SF-1 target genes.

Mutation of Ser1046/7 by replacement with Ala residues blocks desensitization of the EGF receptor protein-tyrosine kinase activity.

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.

We show that the human homolog of Gpi7p, termed hGPI7, binds to and is stabilized by PIG-F and that hGPI7 competes with PIG-O for binding to PIG-F. PIG-F Binds to and Stabilizes hGPI7 and PIG-O Independently. These results are consistent with the hypothesis that overexpression of hGPI7 decreases the biosynthetic activity of PIG-O by decreasing the available PIG-F, thereby destabilizing PIG-O.

The control of Nav density at the cell membrane is crucial to ensuring normal neuronal excitability. Navs are subject to posttranslational modifications that may influence their cell membrane availability. Ubiquitylation is a key process that orchestrates the internalization and subsequent degradation or recycling of Navs. This is accomplished by ubiquitin protein ligases, such as NEDD4-2 (neuronal precursor cell expressed developmentally downregulated-4 type 2).
