Malaria Pharmacology Comments
The P. falciparum cyclic amine resistance locus (PfCARL) encodes a seven-transmembrane domain protein that localizes to the cis-Golgi apparatus of the parasite in both asexual and sexual blood stages [1]. Homology analysis provides an insight into possible function: the S. cerevisiae homolog, Emp65, is a part of a molecular chaperone complex in the endoplasmic reticulum and the mouse homolog, Tapt1, is involved in embryonic skeletal formation, signal transduction, and hormone trafficking [1,3].
Mutations in PfCARL are associated with parasite resistance to two distinct compound classes: the imidazolopiperazines, a novel class of antimalarial compounds that includes the clinical candidate ganaplacide, and the benzimidazolyl piperidines, with the suggestion that PfCARL is a multidrug-resistance gene rather than the common target [1-2].
