Atomic resolution structure of CAG RNA repeats: structural insights and implications for the trinucleotide repeat expansion diseases.

abstract：:LTR units associated with cellular retrovirus-like elements are abundantly present in chromosomal DNA of animal cells. We have analyzed the promoter and enhancer activities of diverse LTR units associated with different members of the murine retrovirus-like family known as VL30. We report here that the structurally he...
