Sex hormone-binding globulin (SHBG) regulates the transport and bioavailability of estradiol. The dynamics of estradiol's binding to SHBG are incompletely understood although it is believed that estradiol binds to each monomer of SHBG dimer with identical affinity (K d ∼2 nM). Contrary to the prevalent view, we show that estradiol's binding to SHBG is nonlinear and the apparent K d. but removal of the same volume of cytoplasm did not. cell's survival.
