- Proteomes:
- UP000005640
Function
- Function:
- 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.
- Catalytic Activity:
- Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1).
