In this paper, we derive from the viewpoint of the effective 4D theory the interaction terms between linearized gravity propagating in N>~2 large extra dimensions and matter propagating into one extra dimension. This generalizes known results for the interactions between gravity and 4D matter in Arkani-Hamed--Dimopoulos--Dvali--type models. Although we assume that matter is described by a universal extra dimension (UED) scenario (with all fields propagating into the fifth dimension), we present our results in a general form that can be easily adapted to various other scenarios of matter distribution. We then apply our results to the UED model on a fat brane and consider some phenomenological applications. Among these are the computation of the gravitational decay widths of the matter Kaluza-Klein (KK) excitations and the effect the width of the brane has on the interactions of gravity with standard model particles. We also estimate the cross section for producing single KK excitations at colliders through KK number-violating gravitational interaction.
