Estrogen receptors
Estrogen Receptors
Estrogen receptors (pronounced: es-tro-jen re-sep-tors) are a group of proteins found inside cells. They are receptors that are activated by the hormone estrogen.
Etymology
The term "estrogen" is derived from the Greek words "oistros" meaning "gadfly" or "frenzy", and "gen" meaning "to produce". The term "receptor" comes from the Latin "receptare" meaning "to receive".
Function
Estrogen receptors are responsible for mediating the effects of estrogen, a hormone that plays a crucial role in the regulation of the menstrual cycle and pregnancy. They are also involved in various processes such as cell growth, differentiation, and apoptosis.
There are two main types of estrogen receptors: Estrogen receptor alpha (ERα) and Estrogen receptor beta (ERβ). These receptors are found in various tissues including the breast, uterus, ovaries, and brain.
