Estrogen receptor-
contains two transactivation
functions, a weak constitutive activation function (AF-1) and a
hormone-dependent activation function (AF-2). AF-2 works by recruiting
a large coactivator complex, composed of one or more p160s,
CREB-binding protein (CBP)/p300, and P/CAF (p300 and CBP-associated
factor), via direct contacts with the p160s. We report here that
independent AF-1 activity also requires p160 contacts. Unlike AF-2,
which binds signature NR boxes in the center of the p160 molecule, AF-1
binds to sequences near the p160 C terminus. We propose that the
ability of AF-1 and AF-2 to interact with separate surfaces of the same
coactivator is important for the ability of these transactivation
functions to synergize.
