PLASMODIUM FALCIPARUM PROFILINPLASMODIUM FALCIPARUM PROFILIN
Structural highlights
Function[PROF_PLAF7] Essential for the invasive blood stages of the parasite. Binds to proline rich sequences in various regulatory formin-like proteins and also to membrane phospholipids. Binds to actin and affects the structure of the cytoskeleton. Weakly sequesters actin monomers (By similarity).[UniProtKB:P86294] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedProfilins are key regulators of actin dynamics. They sequester actin monomers, forming a pool for rapid polymer formation stimulated by proteins such as formins. Apicomplexan parasites utilize a highly specialized microfilament system for motility and host cell invasion. Their genomes encode only a small number of divergent actin regulators. We present the first crystal structure of an apicomplexan profilin, that of the malaria parasite Plasmodium falciparum, alone and in complex with a polyproline ligand peptide. The most striking feature of Plasmodium profilin is a unique minidomain consisting of a large beta-hairpin extension common to all apicomplexan parasites, and an acidic loop specific for Plasmodium species. Reverse genetics in the rodent malaria model, Plasmodium berghei, suggests that profilin is essential for the invasive blood stages of the parasite. Together, our data establish the structural basis for understanding the functions of profilin in the malaria parasite. Structural basis for parasite-specific functions of the divergent profilin of Plasmodium falciparum.,Kursula I, Kursula P, Ganter M, Panjikar S, Matuschewski K, Schuler H Structure. 2008 Nov 12;16(11):1638-48.
