MER21B (Long Terminal Repeat) for ERVL endogenous retrovirus
A brief description of the entry. Suggestions for modification to this description can be submitted using the adjacent pencil icon.
MER21B is a member of a closely related group of LTRs including: MER34, MER39, LTR29, LTR48 and LTR49. Target site duplication is unclear -- either 4 or 5 bp. 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.
Medium reiteration frequency repetitive sequences in the human genome.

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 868 positions long. The average length of non-redundant hits to the model is 458.8. This table shows the number of hits above score thresholds:
|non-redundant||all hits||non-redundant||all hits|
