BLM基因突变与药物因子介绍
bloom综合征基因产物与含有dna解旋酶的desh盒recq亚群有关，具有dna刺激的atp酶和atp依赖的dna解旋酶活性。引起布鲁姆综合征的突变会删除或改变螺旋酶基序，并可能使3'-5'螺旋酶活性丧失。正常蛋白可能起到抑制不适当重组的作用。[由RefSeq提供，2008年7月]
The Bloom syndrome gene product is related to the RecQ subset of DExH box-containing DNA helicases and has both DNA-stimulated ATPase and ATP-dependent DNA helicase activities. Mutations causing Bloom syndrome delete or alter helicase motifs and may disable the 3'-5' helicase activity. The normal protein may act to suppress inappropriate recombination.
