Abstract: We study dynamics of the equation of state parameter for a dark energycomponent non-minimally coupled to induced gravity on a warped DGP brane. Weshow that there are appropriate domains of the model parameters space thataccount for crossing of the phantom divide line. This crossing, which ispossible for both branches of the scenario, depends explicitly on the values ofthe non-minimal coupling and warp factor. The effect of warp factor appears inthe value of the redshift parameter at which phantom divide line crossingoccurs.
