Abstract:
L1-55_XT is a young family of non-LTR retrotransposons that belong to the Tx1 group of the L1 clade. This group is characterized by a strong target-site specificity. L1-55 is inserted at the same site of U2 smRNA, together with some other highly divergent Tx1-like families, including L1-53_XT, L1-54_XT, and L1-56_XT. It encodes the RNA-binding L1-55_XT1p and endonuclease/reverse transcriptase L1-55_XT2p proteins. The 3' terminus is incomplete.
