這個基因編碼的蛋白質是recq dna螺旋酶家族的一員。dna解旋酶是參與多種dna修復的酶，包括錯配修復、核苷酸切除修復和直接修復。編碼的蛋白參與霍利迪連接的處理，姐妹染色單體交換的抑制，端粒維持，并且是遺傳毒性應激抵抗所必需的。這種基因的缺陷與幾種癌癥有關。
The protein encoded by this gene is a member of the RecQ DNA helicase family. DNA helicases are enzymes involved in various types of DNA repair, including mismatch repair, nucleotide excision repair and direct repair. The encoded protein is involved in the processing of Holliday junctions, the suppression of sister chromatid exchanges, telomere maintenance, and is required for genotoxic stress resistance. Defects in this gene have been associated with several types of cancer.
