Summary: The protein encoded by this gene is a member of the RAD51 protein family. RAD51 family members are evolutionarily conserved proteins essential for DNA repair by homologous recombination. This protein has been shown to form a stable heterodimer with the family member RAD51C, which further interacts with the other family members, such as RAD51, XRCC2, and XRCC3. Overexpression of this gene was found to cause cell cycle G1 delay and cell apoptosis, which suggested a role of this protein in sensing DNA damage. Rearrangements between this locus and high mobility group AT-hook 2 (HMGA2, GeneID 8091) have been observed in uterine leiomyomata. [provided by RefSeq, Mar 2016]

Here we provide three coherent sets of isogenic mutants, both in transformed and non-transformed human cells. Importantly, using these mutant lines, we report the unanticipated result that RAD51B has a less crucial role in homologous recombination than the other four paralogs, and find that all RAD51 paralogs are critically important for early functions during homologous recombination

We successfully identified a common variant, rs911263, as being significantly associated with the disease status . In addition, this SNP was shown to be related to erosion, a clinical assessment of disease severity in RA (P = 2.89 x 10(-5), OR = 0.52). These findings shed light on the role of RAD51B in the onset and severity of Rheumatoid arthritis (RA).

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.
