Does DNA do anything other than serve as a repository for genetic information?

I haven't started to look this up yet, but what role does DNA (or RNAs) have in pH balance in the cell and as a sink for ions? All those phosphate groups must have a significant buffering capacity on a microscale. At this year's Canadian society of microbiology meeting, there was an excellent talk about the chelating ability of DNA; implicated in its effectiveness as NETs (the previously mentioned neutrophilic extracellular DNA). Could cells be balancing out their salts with their DNA?
