Previous GeneCards Identifiers for XRCC2 Gene
This gene encodes a member of the RecA/Rad51-related protein family that participates in homologous recombination to maintain chromosome stability and repair DNA damage. This gene is involved in the repair of DNA double-strand breaks by homologous recombination and it functionally complements Chinese hamster irs1, a repair-deficient mutant that exhibits hypersensitivity to a number of different DNA-damaging agents.

GeneCards Summary for XRCC2 Gene
XRCC2 (X-Ray Repair Complementing Defective Repair In Chinese Hamster Cells 2) is a Protein Coding gene. Diseases associated with XRCC2 include familial breast cancer and breast disease. Among its related pathways are DNA Double-Strand Break Repair and Homologous DNA Pairing and Strand Exchange. GO annotations related to this gene include DNA-dependent ATPase activity and four-way junction DNA binding.
UniProtKB/Swiss-Prot for XRCC2 Gene
Involved in the homologous recombination repair (HRR) pathway of double-stranded DNA, thought to repair chromosomal fragmentation, translocations and deletions. Part of the Rad21 paralog protein complex BCDX2 which acts in the BRCA1-BRCA2-dependent HR pathway. Upon DNA damage, BCDX2 acts downstream of BRCA2 recruitment and upstream of RAD51 recruitment. BCDX2 binds predominantly to the intersection of the four duplex arms of the Holliday junction and to junction of replication forks. The BCDX2 complex was originally reported to bind single-stranded DNA, single-stranded gaps in duplex DNA and specifically to nicks in duplex DNA.
