We theoretically study Rashba-Edelstein magnetoresistance (REMR) in a two-dimensional electron gas (2DEG) system with Rashba and Dresselhaus spin-orbit interactions. Starting from a microscopic model of a junction system composed of a ferromagnetic insulator and 2DEG, we derive analytic expressions for the spin and current densities in the 2DEG using the Boltzmann equation. Our findings reveal that the sign of the REMR varies depending on the type of interface. We also discuss the experimental relevance of our results.
