Abstract
Inositol pyrophosphates (PP-IPs) are a specialized group of soluble molecules that have one or two pyrophosphate groups attached to the inositol ring. In model eukaryotes, the best-characterized PP-IPs are PP-IP4, IP7, and IP8. These molecules are involved in several cellular processes, including pathways related to DNA metabolism, such as homologous recombination (HR) and telomere length…
