We examine the JEM-EUSO sensitivity to gravity effects in the context of\nRandall-Sundrum (RS) model with a single extra dimension and small curvature of\nthe metric. Exchanges of reggeized Kaluza-Klein gravitons in the t-channel\ncontribute to the inelastic cross-section for scattering of ultra-high-energy\nneutrinos off nucleons. Such effects can be detected in deeply penetrating\nquasi-horizontal air showers induced by interactions of cosmic neutrinos with\natmospheric nucleons. For this reason, we calculate the expected number of\nquasi-horizontal air showers at the JEM-EUSO observatory as a function of two\nparameters of the RS model.\n
