  We study the bridge between the phenomenological mass matrix model and SO(10)
GUT. Namely, we consider the four zero texture model in the framework of the
renormalizable SO(10) GUT model. This unification gives more stringent
constraints than the case where only either model is considered. However, we
can obtain good fitting by expanding the minimal SO(10) GUT to include 120 in
addition to 10 and \bar 126 in Yukawa coupling and by considering both type-I
and type-II seesaw mechanisms.
