CR1-J1_Pass - CR1 Non-LTR Retrotransposon from Passeriformes.

Abstract:
20% subst. Starts at pos ~250. gag 2-1045 (almost complete), pol 1030-3903, encoding proteins 60%/71% and 76%/85% identical/similar to the CR1-F encoded gag and pol proteins, respectively. Majority of copies (2 of 3) have one C at pos 3336-7 and one G at pos 3356-7 AG, causing a frameshift in the pol gene. While the pol ORFs and proteins of CR1-J2 and CR1-J1 are very similar (92% from 1128 to end 3992), the gag region is only 20% similar, and the encoded proteins are distant from each other compared to gags from other subfamilies. One or the other is therefore the product of a recombination. Since Je seems to have a 170 bp insertion at the recombination point compared to this and other subfamilies, it forms the most likely candidate.
