Abstract: The genome harbors ~3000 copies of SINE2-4_SP elements that are >95% identical to the consensus sequence (some elements are 97% identical to the consensus). Given the lack of target site duplications and 3' microsatellites, the non-LTR retrotransposons involved in retrotranspositions of SINE2-4_SP are expected to be members of the CR1 clade. The SINE2-4_SP family is quite old, it includes ~20,000 copies that are 70-90% identical to the consensus. The ~70-bp 5'-terminus of SINE2-4_SP is not significantly similar to known tRNAs. However, it is ~70% identical to the 5' termini of the SINE2-4a, SINE2-4b, SINE4c consensus sequences, which are distantly similar to the tRNA-like terminal parts of SINE1-1_SP, SINE1-2_SP, and SINE1-3_SP. One copy of SINE2-4c was reported previously as SURF1 retrotransposon [1].
