The function of the type II estrogen binding site (EBS) has yet to be determined. However, a high affinity ligand for the binding site has been identified through HPLC and GC-MS. This ligand, MeHPLA, bears a structural relationship to a group of compounds called "phytoestrogens" which, along with MeHPLA, have been observed to suppress the cellular proliferation of estrogen sensitive MCF-7 breast cancer cells in vitro. Additionally, MeHPLA has been observed to suppress the growth of rat uteri in vivo. The high affinity of MeHPLA for the type II EBS suggests that this interaction is responsible for the observed suppression …
