Schizosaccharomyces pombe checkpoint response to DNA interstrand cross-links.

abstract：:Non-long terminal repeat (LTR) retrotransposons are major components of the higher eukaryotic genome. Most of them have two open reading frames (ORFs): ORF2 encodes mainly the endonuclease and reverse transcriptase domains, but the functional features of ORF1 remain largely unknown. We used telomere-specific non-LTR r...
