GBRED (Gene-Based Repetitive Element Database) is a dedicated database containing repetitive element information which focus on the sequences flanking all human genes, such as 5' untranslated region (5'UTR), and 3' untranslated region (3'UTR). You can click the query button to search the information of repetitive elements surrounding specific genes. If you want to analyze your own sequences, you can click the “RepeatMasker” button to link to RepeatMasker serve which provided by NCKU.
Query result
After selecting options and clicking the search button, genes which match to your selection would be showed in a list. This gene list contains gene id, gene symbol, and gene description, helping you to choose the gene of interest. If you do not select the chromosomal icon in the query page, the gene list might show the chromosomal location of each gene. Click the gene id in the list could see the detail information of selected gene, including
| Chromosome |
Indicate the chromosomal location of selected gene |
| Gene id |
The accession number approved by Ensembl and has a hyperlink to Ensembl webpage |
| Gene symbol |
The official symbol approved by the UCL/HGNC Human Gene NomenClature database |
| Description |
General description of gene in Ensemb |
| Strand |
Indicate the gene is located in plus or minus strand |
| Biotype |
Indicate the gene classes in Ensembl |
| Gene location |
The detail chromosome location of selected gene |
| Transcript |

Graph table
Click the transcript would show the information of repetitive elements located at surrounding region of selected transcript. First, you would see a legend which illustrates the graph of repetitive elements. Below legend, there are some graphs and tables to show information of repetitive elements in different regions. These graphs would show the transcription start site and transcription end site that you could understand the relative location of these repetitive elements and while you click the sections on the graph, there will be a window to show what these sections mean. The table under graph could demonstrate the detail information about each repetitive element, including:
