REPS2, a cytoplasmic protein, is primarily expressed in cerebellum, lung, testis, cerebrum, and kidney. REPS2 forms as complex with DDEF1 and then binds to paxillin. It can also form a complex with activated RAL, which interacts with the Rho subfamily member Cdc42, and with RAL BP-1, which is involved in growth factor signaling via its influence on the RAL signaling pathway. The NF-˚B subunit p65 interacts with the EH domain of REPS2, and an upregulation of NF-˚B activity correlates with a downregulation of REPS2 activity. Decreased expression of REPS2 during progression cancer cells may lead to loss of control of growth factor signalling and, thus, loss of control of cell proliferation. REPS2 may also be an important factor in cancer cell resistance to apoptosis. |
