Abstract:
This is a young family of autonomous Helitrons. It encodes a 2505-aa RepHel protein (pos. 14055-21569) and a ssDNA-binding RPA70-like protein (3 exons at pos. 3828-7844). The RepHel protein is composed of the OTU cysteine protease (pos. 232-347), Rep, Hel, and AP endonulease (pos. 2291-2441) domains. Helitron-1_DR contains also copies of several different transposable elements (they appear old). This transposon is inserted into a long array of (TAA)n microsatellite. Helitron-1N1_DR is a nonautonomous deletion derivate of Helitron-1_DR that was transposed by the Helitron-1_DR-encoded proteins. The genome contains several families of Helitrons coding for both RPA70 and RepHel proteins.
