rtt 4 -1(Ty转座调节因子)是一种细胞突变,其允许酿酒酵母中高水平的自发性Ty 1反转录转座。RTT 4基因与SSL 2(RAD 25)等位,其编码存在于基础转录(TFIIH)和核苷酸切除修复(NER)复合物中的DNA解旋酶。ssl 2-rtt(rtt 4 -1)突变刺激Ty 1反转录转座,但不改变Ty 1靶位点偏好,或增加cDNA或有丝分裂重组。除了ssl 2-rtt之外,ssl 2-dead和SSL 2 -1突变刺激Ty 1转座而不改变Ty 1 RNA或蛋白质的水平。然而,Ty 1 cDNA的水平在ssl 2突变体中显著增加。与SSL 2一样,由RAD 3编码的另一种NER/TFIIH DNA解旋酶中的某些突变刺激Ty 1转座。虽然Ssl 2 p和Rad 3 p是NER所必需的,但Ty 1转座的抑制不依赖于Ssl 2 p和Rad 3 p NER功能。我们的工作表明,NER/TFIIH亚基拮抗Ty 1转座后抑制逆转录或不稳定Ty 1 cDNA。
rtt4-1 (regulator of Ty transposition) is a cellular mutation that permits a high level of spontaneous Ty1 retrotransposition in Saccharomyces cerevisiae. The RTT4 gene is allelic with SSL2 (RAD25), which encodes a DNA helicase present in basal transcription (TFIIH) and nucleotide excision repair (NER) complexes. The ssl2-rtt (rtt4-1) mutation stimulates Ty1 retrotransposition, but does not alter Ty1 target site preferences, or increase cDNA or mitotic recombination. In addition to ssl2-rtt, the ssl2-dead and SSL2-1 mutations stimulate Ty1 transposition without altering the level of Ty1 RNA or proteins. However, the level of Ty1 cDNA markedly increases in the ssl2 mutants. Like SSL2, certain mutations in another NER/TFIIH DNA helicase encoded by RAD3 stimulate Ty1 transposition. Although Ssl2p and Rad3p are required for NER, inhibition of Ty1 transposition is independent of Ssl2p and Rad3p NER functions. Our work suggests that NER/TFIIH subunits antagonize Ty1 transposition posttranslationally by inhibiting reverse transcription or destabilizing Ty1 cDNA.
