it was recently shown that uterine estrogen receptor ( er ) is translocated from the cytoplasm into the nucleus in the form of vero-er x e ( basic er molecule bound with estradiol ) , and the translocation is inhibited by the specific binding of vero-er x e with the cytoplasmic protein factors designated as er-binding factors ( erbfs ) [ `` '' 5s '' '' er-forming factor ( `` '' 5s '' '' er-ff ) , `` '' 6s '' '' er-ff , `` '' 8s '' '' er-ff ] [ murayama , a . & fukai , f.
