RALBP1, also known as RLIP76, is a Ral-binding GTPase activating protein implicated in a number of cell processes, including receptor-mediated endocytosis, cell migration, mitochondrial division and metabolite transport []. It transports glutathione-conjugates of electrophilic compounds and may contribute to the multidrug resistance []. It has been shown to mediate ATP-dependent transport of glutathione-conjugates and doxorubicin in human erythrocytes [].
