Hormone response element

  (Redirected from Androgen response element)

A hormone response element (HRE) is a short sequence of DNA within the promoter of a gene that is able to bind to a specific hormone receptor complex and therefore regulate transcription.[1] The sequence is most commonly a pair of inverted repeats separated by three nucleotides, which also indicates that the receptor binds as a dimer. Specifically, HRE responds to steroid hormones, as the activated steroid receptor is the transcription factor binding HRE. This regulates the transcription of genes signalled by the steroid hormone.

A gene may have many different response elements, allowing complex control to be exerted over the level and rate of transcription.[2]

HRE are used in transgenic animal cells as inducers of gene expression.

Examples of HREs include estrogen response elements (EREs) and androgen response elements (AREs).
