POLDIP2 (Polymerase Delta Interacting Protein 2), also known as PDIP38 or SKIMP2. is a multifunctional nuclear-encoded protein involved in diverse cellular processes. Initially identified as an interaction partner of DNA polymerase δ, it plays a role in DNA replication and repair by modulating the enzymatic activity of the polymerase complex. Structurally, it contains an N-terminal LCN (Ligand of C-terminal domain) motif and a central SAP (SAF-A/B, Acinus, and PIAS) domain, enabling DNA binding and protein-protein interactions. Beyond genome maintenance, POLDIP2 localizes to mitochondria, influencing oxidative metabolism and reactive oxygen species (ROS) regulation through interactions with mitochondrial enzymes like thioredoxin and peroxiredoxin-3. It also participates in cytoskeletal organization by binding microtubules and regulating cell cycle progression. Notably, POLDIP2 acts as a redox-sensitive scaffold, dynamically coordinating nuclear, cytoplasmic, and mitochondrial processes under stress conditions. Its dysregulation has been implicated in pathologies including cancer progression, cardiovascular diseases, and neurodegenerative disorders. Recent studies highlight its role in angiogenesis via VEGF signaling modulation, making it a potential therapeutic target. Despite functional diversity, precise molecular mechanisms across cellular compartments remain under active investigation.
