Welcome to the Horomone Receptor Target Binding Loci Database (HRTBLDb). The HRTBLDb is a collection of estrogen, androgen, and glucocorticoid receptor binding site data.

The publication concerning this database and web service has been published by Nucleic Acids Research! It is titled "HRTBLDb: an informative data resource for Hormone Receptors Target Binding Loci." (Full Article) Cite this database as

Data from high through-put lab techniques (ChIP-chip, ChIP-Seq, and ChIP-PET) are integrated in to this unified database to aid research on the hormone signaling pathways that regulate gene expression. Hormone induced differential gene expression has been implicated in numerous pathological conditions. Given this implication, research in hormone receptor binding sites is increasing at a rapid pace, and with the advent of whole genome analysis, the volume of data generated by this research is immense. HRTBLDb is built to help researchers collaborate and prosper from this explosion of data.
