POLDIP2 Gene

Name polymerase (DNA-directed), delta interacting protein 2
Description This gene encodes a protein that interacts with the DNA polymerase delta p50 subunit, as well as with proliferating cell nuclear antigen. The encoded protein maybe play a role in the ability of the replication fork to bypass DNA lesions. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2014]
Summary
{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\nPOLDIP2 (also known as PDIP38) has emerged as a multifunctional regulator of nuclear DNA transactions. Initially identified as a binding partner for DNA polymerase δ, it interacts with key components of the replication and repair machinery. In particular, POLDIP2 directly associates with specialized translesion synthesis (TLS) polymerases—such as Pol η, Pol λ, Rev1, and even PrimPol—to stimulate polymerase activity, enhance DNA binding and processivity, and help mediate the bypass of lesions (for example, 8-oxo-G) that obstruct replication. Moreover, its loss has been shown to shift the balance of DNA damage tolerance from TLS toward template switching, and under genotoxic stress it redistributes to nuclear speckles to influence alternative splicing events (e.g., that of MDM2)."}, {"type": "fg", "children": [{"type": "fg_fs", "start_ref": "1", "end_ref": "7"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nIn addition to its nuclear roles, POLDIP2 is a nuclear‐encoded mitochondrial protein that contributes to mitochondrial homeostasis and metabolic regulation. It localizes to the mitochondrial matrix where it associates with nucleoid components, suggesting a role in mtDNA metabolism. Moreover, POLDIP2 controls the lipoylation of key mitochondrial enzyme complexes required for optimal tricarboxylic acid cycle function, with its deficiency leading to metabolic reprogramming in vascular smooth muscle cells. Structural studies have revealed a compact two‐domain organization—with flexible, dynamic regions that may facilitate diverse protein–protein interactions—and observations show that under hypoxic conditions, POLDIP2 expression is actively repressed, thereby linking its regulation to fibrotic and cancer cell metabolic adaptation."}, {"type": "fg", "children": [{"type": "fg_fs", "start_ref": "8", "end_ref": "13"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nBeyond its contributions to genome and mitochondrial integrity, POLDIP2 plays a critical role in modulating cytoskeletal dynamics, cell adhesion, and inflammatory signaling. It is a binding partner of cell surface receptors like CEACAM1 and influences the subcellular trafficking of signaling partners in a context-dependent manner. In vascular smooth muscle and lung epithelial cells, POLDIP2 regulates nicotinamide adenine dinucleotide phosphate (NADPH) oxidase activity (notably that of Nox4), which in turn controls the oxidation of actin and focal adhesion maturation. In vascular smooth muscle cells, its involvement extends to the activation of Rho GTPases via intermediaries such as Ect2—processes that impact cytokinesis and cell proliferation. In inflammatory settings, endothelial and epithelial expression of POLDIP2 governs oxidative stress responses and inflammatory cytokine production, and loss of POLDIP2 in retinal pigment epithelium alters complement and immune gene expression while modulating mitochondrial redox balance."}, {"type": "fg", "children": [{"type": "fg_fs", "start_ref": "14", "end_ref": "20"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nPOLDIP2 has also been implicated in disease processes such as neurodegeneration and cancer.
