  We discuss the nuclear parton distribution functions on the basis of our
recently developed semi-microscopic model, which takes into account a number of
nuclear effects including Fermi motion and nuclear binding, nuclear
meson-exchange currents and off-shell corrections to bound nucleon
distributions as well as nuclear shadowing effect. We also discuss application
to the nuclear Drell-Yan process and compare our predictions with data from the
E772 and E866 experiments.
