DIVER2_I is an internal portion of the DIVER2 retrovirus-like element
A brief description of the entry. Suggestions for modification to this description can be submitted using the adjacent pencil icon.
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).
Number of matches to this model that meet the "Gathering" threshold and more stringent "Trusted" threshold. For each threshold, two numbers are shown: (1) the number of matches to this model after removing redundant hits to other models ("non-redundant"), and (2) the total number of matches above threshold, including those with better scoring matches to other models ("all hits").
The model is 4147 positions long. The average length of non-redundant hits to the model is 450.9. This table shows the number of hits above score thresholds:
|non-redundant||all hits||non-redundant||all hits|
