Abstract
Aim: To assess the functional relevance of a putative Major Facilitator Superfamily protein (PF3D7_0210300; 'PfMFSDT') as a drug transporter, using Candida glabrata for orthologous protein expression.Methods: Complementary Determining Sequence encoding PfMFSDT was integrated into the genome of genetically engineered C. glabrata strain MSY8 via homologous recombination, followed by assessing its functional relevance as a drug transporter.Results & conclusion: The modified C. glabrata strain exhibited plasma membrane localization of PfMFSDT and characteristics of an Major Facilitator Superfamily transporter, conferring resistance to antifungals, ketoconazole and itraconazole. The nanomolar inhibitory effects of the drugs on the intra-erythrocytic growth of Plasmodium falciparum highlight their antimalarial properties. This study proposes PfMFSDT as a drug transporter, expanding the repertoire of the currently known antimalarial 'resistome'.
