## Description

This track shows expressed sequence tags (ESTs) downloaded from the Rat Genome Database (RGD). An EST is a partial sequence of a randomly-chosen cDNA, obtained from the results of a single DNA sequencing reaction. ESTs are used to identify transcribed regions in genomic sequence and to characterize patterns of gene expression in the tissue from which the cDNA was derived.

## Methods

The data used to create this annotation were obtained from the file RGD_EST.gff downloaded from the RGD website.

## Credits

Thanks to the RGD for providing this annotation. RGD is funded by grant HL64541 entitled "Rat Genome Database", awarded to Dr. Howard J Jacob, Medical College of Wisconsin, from the National Heart Lung and Blood Institute (NHLBI) of the National Institutes of Health (NIH).
