Summary: Enables damaged DNA binding activity. Involved in blastocyst growth and isotype switching. Acts upstream of or within cell population proliferation; intracellular signal transduction; and neuromuscular process controlling balance. Located in PML body and replication fork. Colocalizes with chromosome, telomeric region. Is expressed in several structures, including alimentary system; brain; genitourinary system; heart; and respiratory system. Used to study Nijmegen breakage syndrome and T-cell acute lymphoblastic leukemia. Human ortholog(s) of this gene implicated in several diseases, including Nijmegen breakage syndrome; acute lymphoblastic leukemia; aplastic anemia; breast cancer; and reproductive organ cancer (multiple). Orthologous to human NBN (nibrin). [provided by Alliance of Genome Resources, Apr 2022]

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.
