When dna is damaged, the atr-atrip complex is recruited to chromatin and is activated to transduce the checkpoint signal, but the precise kinase activation mechanism remains unknown. Here, we show that atrip is phosphorylated in an atr-dependent manner after genotoxic stimuli. The serine 68 and 72 residues are important for the phosphorylation in vivo and are required exclusively for direct modification by atr in vitro.

Phosphorylation by amp kinase, akt (or protein kinase b), or protein kinase a on serine 1179 (bovine) or serine 1177 (human) of enos leads to enhanced activity of the enzyme and, thus, augmented production of no.

The ability of p53 to activate transcription from specific sequences suggests that genes induced by p53 may mediate its biological role as a tumor suppressor. Using a subtractive hybridization approach, we identified a gene, named WAF1, whose induction was associated with wild-type but not mutant p53 gene expression in a human brain tumor cell line. The WAF1 gene was localized to chromosome 6p21.2, and its sequence, structure, and activation by p53 was conserved in rodents.

The demonstration that tradd interacts with traf2 and fadd, and can recruit both to tnfrsf1a, suggested that traf2 and fadd may be involved in tnfrsf1a tradd-mediated signaling. That these interactions define two distinct signaling pathways emanating from tradd (figure 9) is supported by the ability of traf2 and fadd to activate nf-kb and induce apoptosis, respectively.

The enzyme activity of GTP cyclohydrolase I is controlled by a regulatory protein for this enzyme, GFRP, which is a pentamer of identical subunits. GFRP mediates feedback inhibition of GTP cyclohydrolase I activity by BH4, and the inhibition by BH4 is reversed by phenylalanine

This observation suggests that Slit2 may require the Robo2 and Robo3 receptors in this process . Slit2 causes the miRNA miR-182 to release cofilin1 mRNA, potentiating cofilin1 local translation and resulting in growth cone collapse. The use of morpholinos or RNAi to knockdown robo2 and robo3 in X. laevis RGCs, would be useful to further confirm that Robo2 and Robo3 are the receptors involved in Slit2-dependent cofilin1 translation.

We conclude that the interaction of Cdc42 with the partial CRIB motif of IRSp53 relieves an intramolecular, autoinhibitory interaction with the N terminus, allowing the recruitment of Mena to the IRSp53 SH3 domain. This IRSp53:Mena complex initiates actin filament assembly into filopodia.

Inactive PKA exists as a holoenzyme, comprised of two regulatory (R) subunits and two catalytic subunits . In the presence of cAMP, the holoenzyme becomes active by binding two cAMP molecules cooperatively to each R subunit, resulting in a conformational change in the R subunits, thus releasing the two C subunits to phosphorylate downstream targets

Chromatographic fractionation of cell extracts allowed the identification of two distinct enzymatic activities phosphorylating ser-536. 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.

We show here identification of two new members of human mam family (human mastermind-2 (hmam-2) and human mastermind-3 (hmam-3)), which retain characteristics similar to human mastermind-1 (hmam-1) and drosophila mastermind. Both hmam-2 and hmam-3 stabilize and participate in the dna-binding complex rbp-j/cbf-1 protein and the notch intracellular domains that serve as intermediates of the signaling. Both hmam-2 and hmam-3 enhanced the activation of transcription from a target promoter by notch signaling. However, we also show evidence that the activation of the target promoter by notch3 and notch4 is more efficiently potentiated by hmam-2 than by hmam-1 or -3.

Overexpression of antiapoptotic proteins including Bcl-XL and/or Bcl-2 contributes to tumor initiation, progression, and resistance to therapy by direct interactions with proapoptotic BH3 proteins. Release of BH3 proteins from antiapoptotic proteins kills some cancer cells and sensitizes others to chemotherapy. Binding of Bcl-XL and Bcl-2 to the BH3 proteins Bad, Bid, and the three major isoforms of Bim was measured for fluorescent protein fusions in live cells using fluorescence lifetime imaging microscopy and fluorescence resonance energy transfer.
