The hereditary disease Cockayne syndrome (CS) is a complex clinical syndrome characterized by arrested post-natal growth as well as neurological and other defects. The CSA and CSB genes are implicated in this disease. The clinical features of CS can also accompany the excision repair-defective hereditary disorder xeroderma pigmentosum (XP) from genetic complementation groups B, D or G. The XPB and XPD proteins are subunits of RNA polymerase II (RNAP II) transcription factor IIH (TFIIH). We show here that extracts of CS-A and CS-B cells, as well as those from XP-B/CS cells, support reduced levels of RNAP II transcription in vitro and that this feature is dependent on the state or quality of the template.
遗传性疾病科凯恩综合征(CS)是一种复杂的临床综合征,其特征为出生后生长停滞以及神经和其他缺陷。CSA和CSB基因与该疾病有关。CS的临床特征也可能伴随来自遗传互补组B、D或G的切除修复缺陷型遗传性疾病着色性干皮病(XP)出现。XPB和XPD蛋白是RNA聚合酶II(RNAP II)转录因子IIH(TFIIH)的亚基。我们在此表明,CS - A和CS - B细胞的提取物,以及来自XP - B/CS细胞的提取物,在体外支持的RNAP II转录水平降低,并且这一特征取决于模板的状态或质量。
