U13 (DF0001074)
This model represents a noncoding RNA gene. Some ncRNA genes have transformed into, or become assimilated into transposons. Others occur in sufficient copy number that ab initio repeat finders may classify them as repetitive elements. This entry is used to correctly identify the gene and its pseudogenes and prevent misannotation.

Description
A brief description of the entry. Suggestions for modification to this description can be submitted using the adjacent pencil icon.
U13 is an unusual snoRNA that is involved in pre-rRNA cleavage rather than RNA methylation. There are several hundred U13 pseudogenes in the human genome.

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 108 positions long. The average length of non-redundant hits to the model is 105.1. This table shows the number of hits above score thresholds:
| Species | Gathering | Trusted | ||
|---|---|---|---|---|
| non-redundant | all hits | non-redundant | all hits | |
| Mus musculus | 40 | 41 | 22 | 22 |
| Homo sapiens | 385 | 499 | 378 | 484 |
| Danio rerio | 3 | 3 | 1 | 1 |
