Specific acetylation of chromosomal protein HMG-17 by PCAF alters its interaction with nucleosomes.

abstract：:R-loops have been described in vivo at the immunoglobulin class switch sequences and at prokaryotic and mitochondrial origins of replication. However, the biochemical mechanism and determinants of R-loop formation are unclear. We find that R-loop formation is nearly eliminated when RNase T(1) is added during transcrip...
