An interaction with fatty acid binding proteins should be considered, given that 100 μM ketoconazole can compete with the arachidonoyl derivative 20-iodo-14,15-epoxyeicosa-8(Z)-enoyl-3-azidophenylsulfonamide for binding to a 47 kDa protein in cell membranes from U937 leukemic monocyte lymphoma cells [45]. Here, GOT2 is linked to lymphoma.
