Summary: Enables ATP binding activity and DNA ligase (ATP) activity. Involved in double-strand break repair via nonhomologous end joining. Acts upstream of or within several processes, including DNA metabolic process; hemopoiesis; and response to gamma radiation. Part of DNA-dependent protein kinase-DNA ligase 4 complex. Is expressed in liver and metanephros. Used to study DNA ligase IV deficiency. Human ortholog(s) of this gene implicated in several diseases, including DNA ligase IV deficiency; colorectal cancer; multiple myeloma; pancreatic cancer; and prostate cancer. Orthologous to human LIG4 (DNA ligase 4). [provided by Alliance of Genome Resources, Dec 2024]

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.
