    This score cannot be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein. This indicates the type of evidence that supports the existence of the protein. Note that the 'protein existence' evidence does not give information on the accuracy or correctness of the sequence(s) displayed. This subsection of the Names and taxonomy section indicates the name(s) of the gene(s) that code for the protein sequence(s) described in the entry.

    Resistance to CQ and PPQ has been associated with distinct sets of point mutations in the P. falciparum CQ-resistance transporter PfCRT, a 49-kDa member of the drug/metabolite transporter superfamily that traverses the membrane of the acidic digestive vacuole of the parasite 3-9. Here we present the structure, at 3.2 Å resolution, of the PfCRT isoform of CQ-resistant, PPQ-sensitive South American 7G8 parasites, using single-particle cryo-electron microscopy and antigen-binding fragment. The function of Plasmodium falciparum chloroquine resistance transporter PfCRT can be quantified using a Saccharomyces cerevisiae model system Baro, N. K. Pooput, C. and Roepe, P. D. 2011 Biochemistry 50, 6701–6710. Chloroquine CQ is a widely used antimalarial agent, but the emergence and spread of CQ-resistant parasites is a growing global health problem. Although its physiological relevance remains unknown, P. falciparum CQ resistance transporter PfCRT confers CQ resistance through CQ egress from digestive vacuoles of P. falciparum.

  4. Mutations in the Plasmodium falciparum chloroquine resistance transporter PfCRT protein confer resistance to the antimalarial drug chloroquine. Pf CRT localizes to the parasite digestive vacuole, the site of chloroquine action, where it mediates resistance by transporting chloroquine out of the digestive vacuole.

    Resistance to chloroquine of malaria strains is known to be associated with a parasite protein named PfCRT, the mutated form of which is able to reduce chloroquine accumulation in the digestive vacuole of the pathogen. Chloroquine CQ is a widely used antimalarial agent, but the emergence and spread of CQ-resistant parasites is a growing global health problem. Although its physiological relevance remains unknown, P. falciparum CQ resistance transporter PfCRT confers CQ resistance through CQ egress from digestive vacuoles of P. falciparum. To address this issue, recombinant CQ-sensitive or CQ-resistant PfCRT proteins were purified and their transport activities were assessed. Chloroquine CQ has been used for decades as the primary chemotherapeutic drug for the treatment of malaria. The emergence of drug resistance in Plasmodium falciparum has been considered to be because of the excessive use of antimalarial drugs worldwide.
