L1-5_DR (DF0002900)

L1-like non-LTR retrotransposon from zebrafish


L1-5_DR is a family of L1-like non-LTR retrotransposon. This family was active recently (ORF1 and ORF2 have no stop codons). The element is incomplete (its ~300-bp 5' terminus is deleted). It encodes two proteins: a 373-aa L1-5_DR1p (positions 3-1121) and a 1233-aa L1-5_DR2p (positions 1225-4923). These proteins are most close to corresponding proteins encoded by other L1-like elements. This is the same element as the Tx-like non-LTR retrotransposon family MutsuDr2, specifically inserted into 5S ribosomal RNA genes [1].
