| + | [https://www.uniprot.org/uniprot/LORF2_HUMAN LORF2_HUMAN] Has a reverse transcriptase activity required for target-primed reverse transcription of the LINE-1 element mRNA, a crucial step in LINE-1 retrotransposition. Has also an endonuclease activity that allows the introduction of nicks in the chromosomal target DNA. Cleaves DNA in AT-rich regions between a 5' stretch of purines and a 3' stretch of pyrimidines, corresponding to sites of LINE-1 integration in the genome.<ref>PMID:7516468</ref> <ref>PMID:8945517</ref> <ref>PMID:9140393</ref> | ||
