<P> Estrogen receptors ( ERs ) are a group of proteins found inside cells . They are receptors that are activated by the hormone estrogen ( 17β - estradiol ) . Two classes of ER exist : nuclear estrogen receptors ( ERα and ERβ ) , which are members of the nuclear receptor family of intracellular receptors , and membrane estrogen receptors ( mERs ) ( GPER ( GPR30 ) , ER - X , and G - mER ) , which are mostly G protein - coupled receptors . This article refers to the former ( ER ) . </P>
