Es and one proline of the CxxxPxC motif located upstream of the CxCxxC clusters did reduce PP2A binding significantly. Additional studies that relied upon peptide inhibition of the tAg-PP2A interaction without destabilizing tAg suggested that the CxCxxC clusters might indeed influence tAg binding to the A subunit [23,25]. Two recent X-ray crystallographic studies indicate the CxCxxC clusters and

On. Investigations of the genome-environment interactions in Daphnia are ongoing, with the results of the first analyses of differential gene expression patterns in ecological experiments recently becoming available [42?5]. A number of features have been discovered that point to an ecological responsiveness of the D. pulex genome; e.g. a large overall number of genes, organized in the many famili
