Cooperative activity of phospholipid-N-methyltransferases localized in different membranes.

abstract：:Cytosine methylation of binding sites for transcription factors is a straightforward mechanism to prevent transcription, while data on an indirect mechanism, by methylation outside of the factor binding sites, are still scarce. We have studied the latter effect using a model promoter construct. For this, a 69 bp G + C...
