LINE-1 retrotransposable element ORF2 protein is a ~149 kDa protein. Has reverse transcriptase activity required for target-primed reverse transcription of the LINE-1 element mRNA, a crucial step in LINE-1 retrotransposition. Selectively binds and reversely transcribes RNA with a poly(A) tail consisting of at least 20 adenosines. Also has 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 the sites of LINE-1 integration in the genome. Conformational properties of the target DNA sequence rather than specific nucleotides are key determinants of the ORF2p capacity for sequence-specific DNA recognition.
