ABCC5 is a multidrug resistance protein (MRP5) which can transport a wide range of organic anions but especially nucleotides and nucleotide analogues. When overexpressed, ABCC5 can lower the intracellular concentration of nucleoside/nucleotide analogues such as 6-mercaptopurine (6MP), after its conversion into its respective nucleotides (Wijnholds et al. 2000, Ritter et al. 2005, Peng et al. 2008). This may lead to an impaired ability of 6MP to inhibit cell proliferation.
