Abstract: CR1-2_DR is a family of CR1-like non-LTR retrotransposons and it was active in zebrafish recently. The consensus sequence was reconstructed based on 10 copies that are ~2% divergent from it. Approximately several hundred copies of CR1-2_DR are present in the zebrafish genome. The consensus sequence encodes one protein only, CR1-2_DR1p (position 1111-4005). It is a first CR1-like family without ORF1. A 5'-terminal 1110-bp noncoding is present in CR1-2_DR instead of a CR1-like ORF1. The 965-aa CR1-2_DR1p protein is composed of AP endonuclease and reverse transcriptase domains. Endonuclease/reverse transcriptase proteins encoded by CR1-2_DR-like elements were probably involved in proliferation of SINE_DR1. CR1-2_DR and SINE_DR1 share nearly identical 60-bp 3' tails.
