该基因编码reca/rad51相关蛋白家族的一个成员，参与同源重组以维持染色体稳定性和修复dna损伤。该基因在功能上与中国仓鼠irs1sf互补，irs1sf是一种修复缺陷突变体，对多种不同的dna损伤剂表现出超敏反应，染色体不稳定。该基因中罕见的微卫星多态性与不同放射敏感性患者的癌症相关。另外，编码相同蛋白质的剪接转录变体已经被鉴定。[由RefSeq提供，2008年7月]
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 functionally complements Chinese hamster irs1SF, a repair-deficient mutant that exhibits hypersensitivity to a number of different DNA-damaging agents and is chromosomally unstable. A rare microsatellite polymorphism in this gene is associated with cancer in patients of varying radiosensitivity. Alternatively spliced transcript variants encoding the same protein have been identified. [provided by RefSeq, Jul 2008]
