We explore the potential of probing for a new neutral gauge boson that emerges from a topologically nontrivial structure of spacetime, focusing on its couplings to the fermions of the Standard Model. We analyze the current experimental constraints on the mass of the new gauge boson and the radius of the fifth dimension, using the LEP bound and the LHC with 140 
luminosity. In addition, we investigate the expected sensitivity at the ILC to the indirect search of the new gauge boson and its discrimination from other hypothetical gauge bosons like those predicted in the U(1)
and U(1)
models by studying the forward-backward, left-right, and left-right-forward-backward asymmetries.
