Phosphate is one of the essential elements supporting life. Cells accumulate phosphate in the form of a molecule called polyphosphate (polyP), which carries many functions in the physiology of cells that have not been wholly elucidated. Polyphosphate is present in all the types of cells from bacteria to mammals. It consists of a linear polymer constructed with anywhere from a few to hundreds of inorganic phosphate (Pi) molecules linked by phosphoanhydride bonds. Although polyP was described many years ago, difficulties in the study of its roles, most likely due to the many processes polyP is involved in and incomplete information obtained from multiple models and organisms relegate polyP into oblivion. But now, several interesting pieces of evidence are resurrecting the polyP as a key molecule in processes, such as protein folding, carbon metabolism, cell cycle progression, dNTP synthesis, and genomic stability. In this contribution, in addition to briefly summarize the polyP history and roles, we discuss its involvement in supporting cell cycle progression and genomic stability as well as the implications for the truthful replication of genomes.
