Abstract

Estrogen - the female sexual hormone playing the most important role - plays a physiologically significant role, not only regulating in cell signals with second messenger but also being active in regulating transcription. Estrogen receptor (ER) which is a protein accepting estrogen not only play the role of a transcription factor combining with other genes to regulate their activity like other nuclear receptors but also performs external activities, combining with DNA, etc. G-protein coupled ER (GPER) that has been recently discovered exists as 7-membrane and has non-genomic (rapid) signaling. These functions, however, are not extensively addressed. This paper discusses the roles of GPER and its physiological mechanism.
