Also known as: Fancd1; RAB163
Summary: Predicted to enable several functions, including gamma-tubulin binding activity; histone acetyltransferase activity; and identical protein binding activity. Involved in several processes, including establishment of protein localization to telomere; male meiosis I; and telomere maintenance via recombination. Acts upstream of or within several processes, including DNA metabolic process; hematopoietic stem cell proliferation; and signal transduction by p53 class mediator. Located in chromosome; cytoplasm; and nucleus. Is expressed in several structures, including alimentary system; central nervous system; early embryo; genitourinary system; and hemolymphoid system gland. Used to study Fanconi anemia complementation group D1 and breast cancer. Human ortholog(s) of this gene implicated in several diseases, including Fanconi anemia (multiple); esophagus squamous cell carcinoma; hereditary breast ovarian cancer syndrome; melanoma (multiple); and reproductive organ cancer (multiple). Orthologous to human BRCA2 (BRCA2 DNA repair associated). [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.
