MER125 (DF0000722)
Unclassified, putative DNA transposon, MER125 subfamily
Description
A brief description of the entry. Suggestions for modification to this description can be submitted using the adjacent pencil icon.
MER125 is found in mammals and chicken at ~200 copies. A smaller number of copies are identified in Xenopus. MER125 has 20 bp TIRs, and a possible preference for AATT TSDs (not same as TTAA of piggyBac group). Consensus sequences derived from human and chicken genomes are ~95% identical, suggesting conservation. Note that MER stands for MEdium Reiteration frequency interspersed repeat. As such, MERs as a group are a grab bag of DNA transposons and retrotransposons.

Hit Statistics
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 176 positions long. The average length of non-redundant hits to the model is 146.4. This table shows the number of hits above score thresholds:
| Species | Gathering | Trusted | ||
|---|---|---|---|---|
| non-redundant | all hits | non-redundant | all hits | |
| Mus musculus | 171 | 173 | 97 | 99 |
| Homo sapiens | 250 | 255 | 151 | 155 |
