From Wikipedia, the free encyclopedia
The Gq -coupled membrane estrogen receptor (Gq -mER ) is a G protein-coupled receptor present in the hypothalamus that has not yet been cloned.[ 1] [ 2] It is a membrane-associated receptor that is Gq -coupled to a phospholipase C –protein kinase C –protein kinase A (PLC–PKC–PKA) pathway.[ 1] [ 2] The receptor has been implicated in the control of energy homeostasis .[ 1] Gq -mER is bound and activated by estradiol , and is a putative membrane estrogen receptor (mER).[ 1] [ 2] A nonsteroidal diphenylacrylamide derivative, STX , which is structurally related to 4-hydroxytamoxifen (afimoxifene), is an agonist of the receptor with greater potency than estradiol (20-fold higher affinity ) that has been discovered.[ 1] [ 2] [ 3] Fulvestrant (ICI-182,780) has been identified as an antagonist of Gq -mER, but is not selective.[ 3]
