  The Doplicher-Fredenhagen-Roberts (DFR) framework for noncommutative (NC)
space-times is considered as an alternative approach to describe the physics of
quantum gravity, for instance. In this formalism, the NC parameter, {\it i.e.}
$\theta^{\mu\nu}$, is promoted to a coordinate of a new extended space-time.
Consequently, we have a field theory in a space-time with spatial
extra-dimensions. This new coordinate has a canonical momentum associated,
where the effects of a new physics can emerge in the fields propagation along
the extra-dimension. In this paper we introduce the gauge invariance in the DFR
NC space-time. We present the non-Abelian gauge symmetry in DFR formalism, and
the consequences of this symmetry in the presence of such extra-dimension. The
gauge symmetry in this DFR scenario can reveal new fields attached to
$\theta$-extra-dimension. We obtain the propagation of these gauge fields in
terms of canonical momentum associated with $\theta$-coordinate.
