What are SERMs?
Selective Estrogen Receptor Modulators (SERMs) are a class of compounds studied for their ability to interact with estrogen receptors throughout the body. Specifically, researchers investigate SERMs because they can produce different signaling responses depending on the tissue and receptor environment being examined.
Unlike compounds that uniformly activate or block estrogen receptors, SERMs demonstrate selective receptor activity. As a result, this unique characteristic has made them valuable tools in laboratory investigations involving receptor pharmacology, endocrine signaling, and molecular biology.
What Do Selective Estrogen Receptor Modulators Do?
SERMs act on the estrogen receptor (ER), which is an intracellular, ligand-dependent transcriptional activator. Furthermore, there are two different subtypes of ER — ERα and ERβ. ERα is the main medium where estrogen signals transduce at the transcriptional level. Additionally, it is the predominant ER in the female reproductive tract and mammary glands. In contrast, ERβ is primarily in vascular endothelial cells, bone, and male prostate tissue.
Moreover, ERα and ERβ concentrations differ across tissues during development, aging, and disease states. However, many characteristics remain similar between these two types, such as size (~600 and 530 amino acids) and structure. In fact, ERα and ERβ share approximately 97% of the amino-acid sequence identity in the DNA-binding domain and about 56% in the ligand-binding domain.
