==Estrogen receptors==  
==Estrogen receptors==  
(ER) are activated by the hormone estrogen (EST). The activated ER binds DNA and regulates the activity of many genes.  There are 2 forms of ER: α and β and ER dimers can be of αα, ββ and αβ.  ER is composed of 5 domains: N terminal A/B domain can transactivate transcription without binding estrogen; C domain (DBD) binds to Estrogen response elements of DNA; D domain is a hinge region; E domain is ligand binding (LBD) as well as binding the coactivator and corepressor proteins and transactivates gene transcription.<br />

The activated ER binds DNA and regulates the activity of many genes.  There are 2 forms of ER: α and β and ER dimers can be of αα, ββ and αβ.  The 2 forms differ in the tissues in which they are found.  ER is composed of 5 domains: N terminal A/B domain can transactivate transcription without binding estrogen; C domain (DBD) binds to Estrogen response elements of DNA; D domain is a hinge region; E domain is ligand binding (LBD) as well as binding the coactivator and corepressor proteins and transactivates gene transcription.<br />
