Estrogen receptor beta
Estrogen receptor beta (pronounced: es-tro-jen re-sep-tor be-ta), often abbreviated as ERβ, is one of two main types of estrogen receptors, a group of proteins found in cells. The other main type is estrogen receptor alpha (ERα).
Etymology
The term "estrogen receptor beta" comes from the hormone it binds to, estrogen, and its position in the sequence of discovery, being the second estrogen receptor identified.
Function
ERβ is activated by the hormone estrogen, leading to changes in the behavior of cells. It is found in various tissues throughout the body, including the brain, bone, and heart. It plays a crucial role in many biological processes, such as cell growth, cell differentiation, and metabolism.
