GPR158 exhibits different roles in regulating cellular activities in normal and tumor cells. GPR158 facilitates cell proliferation, differentiation, and survival in normal cells by modulating the G1/S checkpoint. Additionally, it suppresses genes associated with the unfolded protein response (UPR). In tumor cells, GPR158 demonstrates dual effects on proliferation, exhibiting context-dependent behavior under high or low activation states.
