L1-2_DR (DF0002490)

L1-like non-LTR retrotransposon from zebrafish


L1-2_DR is a family of L1-like non-LTR retrotransposon. This family was active recently (ORF1 and ORF2 have two stop codons only). The element is incomplete (its ~100-bp 5' terminus is deleted). It encodes two proteins: 469-aa L1-2_DR1p (positions 1-1407) and 1280-aa L1-2_DR2p (positions 1513-5353). These proteins are most close to corresponding proteins encoded by other L1-like elements. This is the same element as the 5S rDNA-specific non-LTR retrotransposon family MutsuDr1 in the Tx1 clade [1].
