Summary: Predicted to enable several functions, including catalytic activity, acting on DNA; damaged DNA binding activity; and microtubule binding activity. Acts upstream of or within several processes, including base-excision repair, gap-filling; immune system development; and intrinsic apoptotic signaling pathway in response to DNA damage. Predicted to be located in cytoplasm and spindle microtubule. Predicted to be part of protein-containing complex. Predicted to be active in nucleus. Is expressed in early conceptus; hemolymphoid system; muscle tissue; nervous system; and sensory organ. Used to study systemic lupus erythematosus. Human ortholog(s) of this gene implicated in pancreatic cancer. Orthologous to human POLB (DNA polymerase beta). [provided by Alliance of Genome Resources, Jan 2025]

To evaluate whether Polb might be causative in senescence induction, the study evaluated the impact of murine Polb nullizygosity on senescence. Unexposed DNA polymerase beta-null primary fibroblasts exhibit a robust increase in the number of senescent cells compared to wild-type (11-fold, P < 0.001), demonstrating that loss DNA polymerase betais sufficient to induce senescence.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
