DIVER2_I (DF0001565)

DIVER2_I is an internal portion of the DIVER2 retrovirus-like element

Description

DIVER2_I is an internal portion of the DIVER2 endogenous retrovirus. LTR of DIVER2 is DIVER2_LTR. DIVER2 is an ancestral form of DIVER. There are a few copies of DIVER2 proviral sequences flanked by both LTRs. There is 2-6% divergence between the flanking retroviruses, therefore DIVER2 has been integrated into the D.melanogaster genome about 2 Myr ago. Target site duplication is 5 bp-long. DIVER_I internal sequence preserves remnants of ~1200-aa polyprotein (nucleotide position 436-4147) similar to the ones encoded by retroviruses from the BCDRP group. The polyprotein is composed of gag (positions 436-1583), reverse transcriptase (positions 1590-3400) and integrase (positions 3406-3846).
