Abstract: The 70-bp 5' terminal portion of SINE2-1_HM is similar to tRNA-Ala. The genome contains >10000 copies of SINE2-1_HM. Some of them are 100% identical to each other (~99% identity to the consensus); therefore, SINE2-1_HM is likely transpositionally active. Autonomous non-LTR retrotransposons involved in retrotransposition of SINE2-1_HM and SINE2-2_HM are not known yet. Despite the poly(A)-tail present in SINE2-1_HM and SINE2-2_HM, these autonomous retrotransposons are not from the L1 clade since SINE2-1_HM and SINE2-2_HM elements are not flanked by target site duplications. Studies of evolution of SINE2-1_HM and SINE2-2_HM could be complicated by the fact that some of these elements were inserted into different transposons forming composite TEs and transposed independently of their major mechanism of retrotransposition. The SINE2-1_HM and SINE2-2_HM consensus sequences share only 58-bp 5' terminus (72% identity).
