Repetitive element conserved in all mammals, unknown type
A brief description of the entry. Suggestions for modification to this description can be submitted using the adjacent pencil icon.
Very low copy number in human. Inspection of the 100 vertebrate genome alignment suggests that most of these copies are conserved in mammals. Evidence for this being a TE is a borderline translated BLAST hit to a Ty3/Gypsy-like retroelement from frog (XP_004916550.1) using a consensus derived from the seed alignment. This could represent an ancient exaptation event, or this might be a false positive match between a retroelement POL gene and a functional noncoding element in mammalian genomes.
Distinct groups of repetitive families preserved in mammals correspond to different periods of regulatory innovations in vertebrates.

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 162 positions long. The average length of non-redundant hits to the model is 140.8. This table shows the number of hits above score thresholds:
|non-redundant||all hits||non-redundant||all hits|
